6 Things to know about electrical systems and floods

April 24th, 2013 No comments

In the wake of all these Midwest floods we thought this was a relevant topic.  Many kinds of contractors get called during the aftermath of floods and water events.  Make sure they know and understand what water does to electrical systems!

(6) Things to know regarding electrical systems and water

  • If electrical service entrance equipment has been submerged it needs to be inspected, dried out, and have all the connections re-made with anti-corrosion compound.  In some cases total replacement may be the only guaranteed option for safety
  • Circuit breakers that have been exposed to direct water, extreme weather, high moisture, or active water need to be replaced, no exceptions! Circuit breakers are over current protection devices – they are the main safety device in the electrical circuit and need to work
  • Any outlet or switch that has been submerged or effected by direct water or moisture needs to be removed and replaced – water means corrosion and corrosion is the enemy of good electrical connections
  • Romex type building wire that has been submerged should be replaced.  It is nearly impossible to get it fully dried out… the plastic casing acts as a hose and retains water that over time will leak back out into the device connections and cause corrosion
  • Ground mounted lights that have been submersed can be full of water days after a flood event – these should be checked out carefully to insure safe operation when switched back on
  • Remember that electricity and water do not mix, and most electrical products are not tolerant of being submerged.  Just because it “came back on” does not mean it is safe to use or is in the same condition it was prior to being effected by water

If you have any questions let us know – we do site consults an can get you on the right path to a speedy and safe restoration.

 

How a custom home should be wired – The ARTISAN WAY!

February 10th, 2012 No comments

A little known fact in the building trades is how cheap the workmanship has really gotten.  Once upon a day – when you put your companies name on it that meant you stood behind what you did, period.  In this day and age low bid gets the job.  Sure there are some stand up exceptions to this, but for the most part the war cry of  “get it done fast and cheap” is the norm.  In that process the real loser is the homeowner, and in most cases they don’t even know it happened.

Here is one example:  most sub-contractors are only required as part of the bid process to back their work with a 1 year warranty to the builder, and most builders only offer a stock 3 to 5 year warranty on the whole project.  Frankly speaking – we think that is despicable!  Your home is likely the single  largest investment you will ever make – how is it that you can get a great warranty on a car these days but not your house?

 

 

Here are 25 reasons an Artisan Electric custom home project stands out from the rest

1)      Our jobs are run and staffed by Journeyman electricians, no exceptions!

2)      We use only quality materials and practices, no exceptions!

3)      No 15 amp – 14 gauge “cheap-o” circuits.  We use only 20 amp (or larger) rated branch conductors

4)      We only use copper buss commercial load centers and service entrance equipment

5)      We use separate circuits for each room (excluding lighting) in a home.  This avoids problems with today’s computer and electronic equipment, as well as new high-demand appliances

6)      We do not share neutrals for any of our circuits

7)      Artisan Electric is the highest rated Angie’s List contractor in a 30 mile radius of Lafayette – go take a look

8)      Arc-fault circuit breakers are used on bedroom power circuits per NEC requirements

9)      We do not use feed thru wiring practices or “stab in the back” wiring methods. All devices are pig tailed at the point of use

10)   We only use steel junction boxes with threaded ground screw connections.  Do it once, do it right!

11)   Our employees take extensive safety training (CPR, First Aid,) and OSHA safety certifications

12)   All of our employees have been thru a BAT certified 4 year electrical apprenticeship program and have testing documentation

13)   We use Hubbell 15 and 20 amp commercial rated receptacles, with dedicated 20 amp rated receptacles for all appliance loads. We only use 20 amp rated commercial GFCI outlets

14)   We put spare pipes to the garage / attic / outdoor living / and crawl spaces for future use.  It is our job to look out for your total lifespan needs

15)   We use only 1000 watt or larger rated Lutron dimmers for our projects – with CFL / LED dimmers for any unique lighting requirements

16)   All of the products we use for construction come from pro vendors – no “home store” off brand or B-Stock items are used for our installs

17)   Artisan Electric is a member of a certified recycling system, all wasted generated by us will be sorted and recycled with Resolve Earth Solutions

18)   We provided “As-Built” drawings for our projects upon completion – you will know exactly what you paid for

19)   We understand the importance of good housekeeping, our projects are cleaned daily – we won’t leave a mess for you

20)   We have the experience, expertise, professionalism, and training to handle the job – without creating stress and re-work for the other trades, project supervisors, and especially to the home owner

21)   Our bids are comprehensive, ethical, and truthful.  We provide a line item of the circuits to be used to our clients so they KNOW exactly what they are paying for and what it includes

22)   Our bids cover the items the others leave out, including options for audio, video, internet, exterior lights and audio, home theater, and smart home wiring

23)   Whole house surge protection comes standard with our bid package

24)   We are an authorized Kohler GenSet dealer.  We can provide best in generator solutions for natural gas and LP systems -including pre-wire options for future generator hook-up / smart transfer interface panels / legendary Kohler reliability and certified maintenance plans

25) A custom home wired the Artisan Electric way comes with a 10 year transferable workmanship warranty – we do it right, period!

January 19th, 2012 No comments

2011 was an exciting year for us here at Artisan Electric, we closed out the year as our best ever!  We had growth nearing 20% for our second year in a row – and have finally slayed many of the demons that came with 2008 / 2009 crash!  We meet some very specific goals in 2011, here our a few highlights:

  • Implementing a certified recycling plan with Resolve Earth
  • Forming a partnership with Buckeye Power Sales to become a Kohler generate dealer / installer
  • Forming a partnership with Surge Assure to offer advanced residential and commercial surge protection solutions
  • Being award for the second year in a row the Angie’s List Super Service Award for our area
  • In depth web and social media development – hitting the 1500 click thru a month mark on our web platform (primary site / blog)
  • Attending the X.commerce / Magento web development conference in San Fransisco – this was truly an awakening
  • Developing the Monticello Electric brand and companion web site
  • Our continued involvement with the RPM Chapter of Business Networking International (now ranked number#1 in the state)
  • Working with Food Finders Food Bank and the mobile pantry program to help feed the hungry

How old are your smoke detectors? When was the last time you tested them?

November 4th, 2011 No comments

The home heating and holiday season is approaching so now is a good time to inspect your smoke detectors and carbon monoxide detectors to make sure they are in proper working condition.  It’s also a great time to consider having a professional electrician upgrade your smoke detectors to meet the current safety standards and local codes.

Ninety-six percent (96%) of all homes in the US have at least one smoke detector according to a 2010 National Fire Protection Agency (NFPA) sponsored telephone survey.  But, only 75% of the homes in the US have a working smoke detector.  According to NFPA data from 2005-2009, smoke detectors sounded in only half (50%) of the fires reported to US fire departments and almost two-thirds (66%) of home fire deaths resulted from fires within homes with non-working or no smoke detectors.  Twenty-four percent (24%) of the deaths occurred in homes that had smoke detectors installed, but the detectors failed to sound.

Smoke detector installation code requirements are governed by the National Fire Alarm Code, NFPA 72.  Prior to 1993, smoke detectors were governed by NFPA 74.  The code requirements have changed over time, with the goal being the improvement of personal safety by providing earlier warning of fires through the home’s smoke detectors.  Prior to 1989, single, stand-alone battery operated smoke detectors were required to be installed in homes or in new construction.  In 1989, newly constructed homes were required to have interconnected (hardwired) smoke detectors on every level of the home and outside of sleeping areas.  With inter-connected detectors, all the units would sound if any one detector triggered and alarm.  In 1993, the code was revised to include a requirement for the hardwired smoke detectors to be in every bedroom or sleeping area in addition to the units on every floor.  In 1996, the code requirements were modified to require the hardwire smoke detectors also have battery back-ups to ensure operation during power outages.  This battery back-up must be able to maintain power to the smoke detector for a period of seven (7) days after the low battery warning begins to sound.

While governed by NFPA 72, smoke detectors are also covered or addressed in the National Electric Code (NEC).  The 2002 NEC saw a major revision with the new requirement of Arc Fault Circuit Interrupters for all bedroom circuits including lighting and smoke detector receptacles.  Local codes and local jurisdictions have overridden the NEC in many areas over concerns that nuisance tripping of AFCI circuits can leave the bedroom unprotected if the battery back-up fails.

Both the NFPA 72 and NEC require that smoke detectors have visible Power-On indicators (usually green LEDs) and be supplied by either a dedicated branch circuit or the unswitched portion of a branch circuit for power and lighting.  The NFPA 72 and NEC prohibit the use of a GFCI to supply power to smoke detectors.

Most electricians will strongly recommend that older homes or those built before the adoption of the 2002 NEC, should have the smoke detectors updated to meet the new code requirements and be installed on a dedicated, interconnected circuit with a smoke detector on all floors and detectors in all bedrooms or sleeping areas.  In addition, most electricians also recommend the addition of a hardwired, interconnected Carbon Monoxide detector with battery back-up be added the smoke detector alarm circuit near the furnace and hot water heater.  Alarm strobe lights are highly recommended for families with individuals that are hard of hearing or hearing impaired to alert them of alarm conditions.

 A parting tip:

Always change the back-up batteries in all smoke detectors or carbon monoxide detectors on your birthday and test the detectors at least four times a year, at the change of each season.  This ensures that the batteries are always in good condition and ready to offer the extended coverage in the event of a power loss.  Also, if you do experience and extended power loss for more than a day or two, it’s recommended that the batteries in all smoke detectors be replaced to ensure they are in top condition for the next power loss.  Batteries are a small price to pay to ensure the safety of you and your loved ones.

Dimming CFL and LED lamps

October 3rd, 2011 No comments

Dimmers & CFL or LED Bulbs

 

We’ve previously addressed the upcoming phase out of the incandescent bulbs and discussed the different Pros & Cons of Compact Fluorescent Light bulbs and LED bulbs.  Maybe you are replacing incandescent bulbs as the burn out, or selectively replacing the bulbs in certain light fixtures.  Have you tried CFLs or LED bulbs in the dining room chandelier or any of your other fixtures with dimmer switches?  Did the new bulbs work?  The result was probably bulbs that did not dim at all, flickered at lower light levels, or had a limited dimming range.  Perhaps in disappointment you thought, “I know I bought the CFL lamps that are dimmable”  and you double-check the packaging to confirm you did buy the correct bulbs.    What the heck is going on you ask?!  Odds are the bulbs are not the problem, the old style dimmer switch is the problem.

 

 

The dimmable CFL and LED bulbs need to be used in conjunction with a new CFL and LED rated dimmer switch.  This is very important for a couple of reasons, but the most important reason is that the new CFL and LED rated dimmers are UL Listed for use with these new bulbs.  This means the dimmer switch was tested to the UL Lab’s standards to be safe and not cause fires or electrical shocks when used with CFL or LED bulbs.  The other reason to use a new dimmer switch is that they have an adjustable dimming range when being used with CFL or LED bulbs instead of incandescent bulbs to prevent flickering.

Many companies offer CFL and LED approved dimmer switches.  Leviton and Lutron are probably the most commonly available brands.  They can be picked up at any local big box home improvement store.  Dimmer switches are relatively easy to install yourself after you have turned off the power to the circuit at the load center.  If you are not comfortable or confident in your abilities to work on your electrical circuits, please be safe and consult your preferred local electrician.

Arc-Fault Circuit Interrupters… say what?

July 20th, 2011 No comments

AFCI Circuit Breakers

 

AFCI breakers are Arc-Fault Circuit Interrupters.    They are similar in appearance to GFCIs (Ground-Fault Circuit Interrupter) breakers and they first came into the market in 1999. They are designed to prevent fires from arcs (sparks) that are not a normal part of a circuit’s operation.  Normal and safe arcs occur in switches and in electric motors such as fans and vacuums.  They are generally very small or very short in time duration.  The devices that produce these normal small arcs are designed to shield and protect people as well as the surroundings from the arcs so there is no fire risk.  Dangerous arcs can occur when devices fail, cords are damaged or the wiring becomes faulty as often happens with receptacles using stab-in connections.

The original AFCIs were branch type units designed to trip on 75 amperes of arcing current from the line wire to either the neutral or ground wire.  They were required to be installed for all bedroom circuits with the 2002 National Electric Code but did not provide personal protection from ground faults so kitchens, bathrooms, and garages still required GFCI circuit protection.

The 2008 revision of the National Electric Code changed the requirements to include Combination Type AFCIs for all 15A or 20A circuits in a dwelling except kitchens, bathrooms, laundry rooms and unfinished basements, which still require GFCI protection.  The combination AFCI added additional protection for series arcing at 5A and personal ground-fault protection which trips the breaker at a 5mA level for ground faults while maintaining the original 70A parallel rating for line to neutral arcing.  AFCIs still protect the circuits from the traditional overloads, short circuits and overheating breakers.  The Code still does not require AFCIs for kitchens, laundry areas, bathrooms and garages since it requires the use of GFCI breakers or GFCI receptacles in these locations.  Adding AFCI breakers to feed GFCI receptacles is not recommended due to the fact that nuisance tripping can frequently occur.

All of the major manufacturers offer combination AFCI breakers so replacing older standard breakers with the new combination AFCIs is possible in all but a small percentage of applications.  The primary exception being the “cheater” breakers that feature two circuit in one mounting position that are typically used when a smaller load center has no spare positions for mounting new breakers.   Local jurisdictions and local codes vary, so always contact your local officials or local electricians for assistance.

On a final note, if the wiring in your home does not have the combination AFCIs and you have them added for the additional fire protection they offer, contact you r home owner’s insurance agent and let them know your electrical panel was updated.  You may qualify for a lower annual premium or other discounts which can help offset the cost of the upgrade.

Generators – Have You Considered Installing a Permanent Standby Generator?

June 16th, 2011 No comments

Have you experienced multiple extended power outages in the last two years that caused the loss of the food in your refrigerator and freezers?


Have you had electronics within your home damaged because of surges, spikes or sags in your utility power?


Do you want to be less reliant on a strained and aging power grid?


Unfortunately, today’s residential power grid is obsolete.  It’s really starting to show its age.  It’s failing more regularly in more urban settings where the demands continue to increase, the power lines are run above ground on utility poles, and the trees overhang the lines.  Severe weather is becoming more common so the power is interrupted more often from tree limbs falling through the lines.  Rolling brown outs, sags, surges, and spikes are becoming more common due to the increased demand, especially in the hotter summer months.  The reliability and quality will only get worse before enough Americans demand a change at the government level to effect policies to drive improvements and more reliable power grids.

If you have experienced any of the above scenarios it might be time to consider a permanently-installed residential standby or “back-up” generator.  Today’s residential generators are capable of automatically transferring the selected household circuits over to the generator in less than 10 seconds.   The LP or natural gas powered units are clean, quiet, and nearly odor free.   There are even greener options coming soon within the next few months to a couple of years away.  These units will be capable of running on 100% biodiesel, straight vegetable oil, or locally generated biogas.

Most homes only need 10kW to 14kW capacity for basic emergency loads and units are available that can provide 100% complete coverage for even 6,000 square feet or more of living space.  While it is possible to purchase a residential generator from the local home improvement warehouse or even online, the best way to determine your needs and ensure the unit is properly installed, is to work with your local dealer to determine your current electrical demands.  The dealer will also help you find areas where the energy efficiency of your home can be improved, and determine how much capacity you will need for your critical loads.  Even if you decide to invest in a whole house solution, working with your local dealer to improve the energy efficiency of your home will save you thousands of dollars over the life of the system in addition to lower the initial cost of the unit since a smaller unit would suffice.

If you are in the early phases of a new housing construction project or about to undertake a major renovation of an existing home, now would also be a great time to include a permanent standby generator as part of the energy independence and energy efficiency plan for the home.

Surge Protection – pro solutions from Artisan Electric

June 7th, 2011 No comments

Today’s homes are more reliant than ever on appliances and electronics that are controlled by extremely sensitive microprocessor circuits. These circuits are easily damaged or disrupted by power surges originating both inside and outside the home.  Artisan Electric has partnered with Surgeassure to provide and install a line of residential protection products designed to protect the electrical and electronic equipment in your home using the Total Zone “staged protection” strategy which divides your home into three zones.

  • MAIN ZONE: 1st stage of defense and the key to protecting your home.  Main Zone Protectors are installed at the main power panel, cable TV/satellite service entrance, and telephone / broadband internet service entrance
  • INTERIOR ZONE: 2nd stage of defense for sensitive electronics inside the home
  • EXTERIOR ZONE: 3rd stage of defense for equipment located outside the home such as the air conditioning unit, pool pump or well pumps

WHAT ARE POWER SURGES AND WHERE DO THEY COME FROM?

• Extremely brief spikes in electrical power that burn up electrical circuits inside appliances and electronic equipment.

• 30% enter the home through the power lines, telephone lines and cable TV/satellite lines >These are the most damaging.

• 70% are generated by equipment inside the home from motors and large appliances turning off and / or premature failure.

WHAT DAMAGE CAN POWER SURGES CAUSE?

• PHYSICAL DAMAGE:  The most noticeable and dramatic, these are the result of large power surges originating outside the home.

• DISRUPTION:  The computer locks up or shuts down, loss of valuable data from hard drives and media storage devices, the Blu-Ray DVD player malfunctions, the washing machine shuts down before the end of the cycle for no reason, computer modem and wireless devices need resent and have problems staying stable, HD TV picture pixelates or SAT receivers have issues staying synched.

• DEGRADATION:  Also called “electronic rust,” it shortens the lifespan of your equipment so that it mysteriously stops working sooner than one would expect… “why do we keep having problems with the garage door opener?”

Have questions or concerns about surge protection for your home or business?  Contact us today and let the pros at Artisan do a free site assessment and help design a system to protect your investments.

CFL’s vs. LED’s – What you need to know!

Mercury in new light bulbs not being recycled, escaping to environment

 

 

Are the energy efficient CFL bulbs creating a bigger problem than they are solving?

 

 

 

Most homeowners today are aware that incandescent light bulbs are very inefficient and they only convert 10% of the energy used into light with the rest of the energy wasted as heat.  Many of us have made the switch to Compact Fluorescent (CFL) bulbs that are four times more efficient than incandescent bulbs and have been rewarded with lower electric bills each month.  But each CFL contains 3-5mg of mercury and they need to be properly recycled to minimize their negative effect on the environment.  New studies show that only 2% of home owners properly recycle their used CFL bulbs and only 33% of businesses properly recycle all fluorescent light bulbs.  Large home improvement stores now offer free CFL recycling drop boxes, but do you recycle every one you purchase?  How many have been accidentally dropped while being changed?  When the bulb shattered, mercury was released into the immediate environment.

So is there an energy efficient option that has less environmental impact and less direct health risks to homeowners?

 

 

Yes.  LED replacement bulbs have made great strides in recent months and it is now possible to find 60W equivalent bulbs that closely match the light color and output of the old incandescent bulbs.  LED bulbs contain no mercury and most are now RHoS compliant which means that they contain no harmful materials.  LED lighting is 90% more efficient than incandescent bulbs and 50% more efficient than CFLs.  They also last an average of 50,000 to 60,000 hours versus CFL’s average life of 7,500 hours and an incandescent bulb’s average life of 1500 hours.

 

 

Let’s compare specifications of the three major bulb types and then get back to the issue of mercury in CFLs:

Specification

Health and Safety

Bulbs can shatter

Bulbs can shatter and release mercury, emit more UV light which can fade or damage art and photographs

Most are plastic with limited risk of shattering, no mercury

Life Cycle Cost

High due to inefficiency and frequent replacements

Medium costs, lower energy usage and longer life

Lowest over lifetime due to lowest energy use and very long life

Availability

Widely available now, but production will be phased out in 2012 and bulbs will be obsolete in 2014

Widely available

More limited availability, but continuing to increase

Using the table above we can draw some conclusions and further investigate the advantages and disadvantages of CFLs and LEDs:

 

LEDs:

Advantages-

+ Use much less power resulting in even lower electric bills and less pollution from power plants

+ Very long life, 10X or more longer than CFLs

+ Generate less heat than CFLs for less load on air conditioning systems, reduced danger of burns from touching bulbs, reduced fire hazard

+ LEDs are typically RoHS compliant so there are no hazardous materials in the bulbs, minimal environmental impact and no risk of personal exposure to mercury.

+ LED emit no Infrared or Ultraviolet light, so no risk of damage or degradation of   artwork, photographs, or other sensitive items from exposure to the light.

+ LEDs are instant on and not damaged by frequent power cycling.

+ LEDs operate in freezing temperatures

Disadvantages –

- Initial cost.  Though much cheaper over their total lifetime, the initial cost of the LED bulbs prevents most home owners from a full conversion at one time.  They need to be swapped in as CFLs fail or replace hard to reach bulbs where their long life is an immediate benefit.

- Less bulb style options, lower equivalent wattage, and no 3-way bulb options mean that certain applications like chandeliers or decorative globe bulb applications have no LED substitutes at this time.

- LEDs are much more directional, which part of the reason they are so much more efficient, but true omnidirectional incandescent equivalents are just reaching the market and they are more expensive than the spot and flood bulb equivalents.

- LEDs are sensitive to heat.  Very hot locations do not allow the bulbs to cool properly and their life is shortened, though no exact data is available at this time to give clear upper temperature limits as it applies to residential applications.

CFLs:

Advantages-

+ Available in 3-way bulb configurations with 50W-100W-150W equivalents with a maximum consumption of 37W.

+ Better in omnidirectional lighting applications like the incandescent bulbs they replace.

+ CFLs in dimmable candelabra form are now available that are 40W equivalent outputs, finally making CFLs a viable option for chandeliers and other decorative lighting, though the aesthetics of the CFLs is still much lower than the incandescent bulb they replace.

+ CFLs have more temperature or color range options and the warm white now closely matches the incandescent bulbs they replace.  CFLs are also available in full spectrum output which is a benefit to individuals who suffer from Seasonal Affective Disorder.

Disadvantages-

- Mercury, all CFLs contain between 3mg and 5mg of this heavy metal which is a neurotoxin.  It poses a high threat to the environment when failed bulbs are not recycled properly and it is an immediate, local danger when a CFL is broken.

- While they last longer than incandescent bulbs, CFLs light output diminishes quickly over time and can be reduced by more than 50% over a year’s time.  By the time they fail, their output may only be 20% of the original rated output.

- CFLs, have unpredictable failure modes.  Most emit smoke or odors and there are numerous reports of CFLs catching on fire or exploding when failing.  Many tend to pulse or strobe as they fail which can trigger headaches or seizures in those sensitive to rapid changes in lighting.

- CFLs lifetimes are rated for very specific conditions.  They are not intended to be cycled on and off more than a couple of times a day.  The more a CFL is cycled on and off, the shorter its overall life will be.

- Most CFLs will not even turn on in near freezing conditions and if they do, then the warm up time is much longer and their light output is greatly reduced.

 

The Clean Energy Act of 2007 set new standards for energy efficiency requirements and incandescent bulbs do not meet the new standards.  By 2014 incandescent bulbs will be phased out of the US and their production will begin to cease as early as next year in 2012.

This really leaves only two energy efficient options for lighting in residential applications, the CFL and the LED bulb.  As advances in LED technology continue to reach the consumer market, the future for CFLs will begin to fade faster than their light output over time.  However, the 5mg of mercury in each CFL bulb is still one fourth to one half the amount of mercury released into the environment versus the emissions from the coal-fired power plant needed to produce the 60 watts of light with an incandescent bulb.  So a CFL bulb is still better for our environment than incandescent bulbs.  However, Americans need to do a much better job of properly recycling their fluorescent bulbs.

The National Electrical Manufacturers Association in Washington, D.C., offers information on fluorescent light recycling at www.lamprecycle.org.

As incandescent bulbs are phased out, the LED bulb will continue to be the better choice for home owners and the environment since it is 50% more efficient than CFLs and it contains no mercury within the bulb; offering a greater than two for one reduction in amount of mercury released into the environment.
