What electrical technologies are going to lead us in 2010?

Green today gone tommorow

Green today gone tommorow

With all the talk you here about green this and green that CFL’s, LED’s, GFCI’s, AFCI’s, Whole house surge protectors, Networking, Cat 5, Cat5e, Cat6, etc.. It can leave the consumer lost in information overload.

Technologies are being invented faster than we can consume them, which in effect causes a learning gap in how the new products are to be used and which ones are best.

Even as an electrical contractor in Seattle I struggle to keep up with the technologies and products being produced today. This opens up a new category or specialty for the contracting world. As an electrician I remember my roots back in Chicago, where we wire all are homes in pipe the old fashion way. Its simple install the conduit and pull the conductors through the pipe, connect a device or two and you were done. If a new circuit was ever needed you just simply pull through another circuit through the conduit and you are done. Now with romex or type nm cable you can save a lot of labor installing these cables and of course no pipe to add to the costs of installation. However if you need to add a circuit to an existing home or office it usually requires some drywall repair and more labor than just pulling over a new circuit in pipe.

As a consumer I like to pay for performance. Why should I spend all this extra money on these new “Green Technologies” Because they save you money in the long run and they protect you and your family from fires that are caused by electrical malfunctions.  Just see for yourself, look at your utility bill and see your electrical usage then go to your local hardware store and purchase some compact fluorescent lamps “CFL’s” in place of you incandescent lamps and see the difference in wattage use. You will be surprised. Oh, they usually don’t tell you but try to dim the fluorescent lamps oops that oscillating light looks terrible. Now you need to buy a new switch to replace that old dimmer you bought to save energy. Look, this is why you should always research before you buy into a trend. You can dim a fluorescent however you may need to consult with an electrician first.

I will tell you one thing and that is we are heading in the right direction and while not all technologies are practical for your application there are many ways to improve your comfort and safety. I personally would stay away from electrical products that seem cheap or are just too good of a deal to pass up. After all these products are going into your home and the cheap products are usually the first round design for the manufactures and are made of cheaper components to get them to market faster.

In the end I believe that LED lighting, solar energy and wind power are going to be more trendy as we look forward to 2010 and beyond the prices Will have to come down before the general public excepts these products as a standard replacement to older technologies.

Let’s make 2010 a safe year and educate ourselves to better understand these ever changing technologies and to use them wisely so as to protect lives and promote high standards for others to measure.

Portable Generators

Filed under: Uncategorized — Tags: , , , , , , , , , — Administrator @ 10:56 pm

transferswitchMany construction teams use a portable generator to power tools and lights at a remote site. Sports officials may also bring in a portable generator to aid in night play or to run an electronic timer/scoreboard. Most commonly, residents and businesses left without power after a weather event will use a portable generator to keep vital appliances operating. A portable generator usually has enough power to keep a freezer, refrigerator, television and some lights working.

Because a portable generator uses a combustion engine to generate electricity, it must have several regulators on board. The engine must turn at 3600 rpm in order to generate the standard 60 Hz of alternating current in North American homes. In order to control engine speed, a portable generator uses a ‘governor’ which mechanically keeps the engine from spinning too fast. A voltage regulator also keeps the output at 120 volts, which keeps electric motors from burning out.

For safety reasons, a portable generator must be operated under dry conditions in a ventilated outdoor area. Carbon monoxide fumes can build up from the exhaust of the generator’s engine, so indoor use is strongly discouraged regardless of the ventilation system. Touching a working portable generator with wet hands can cause electrocution. A canopy can be placed over the generator to protect it from the elements, but the ground below it should be dry.

A portable generator is designed to be a temporary electrical generator, measured in hours of use instead of days. Size does matter when it comes to the capacity of any portable generator. The key measurement is total wattage. All electrical motors need more power to start than to run. Before plugging appliances into the generator, add up the total number of watts all of them will require. This information should be found on a plate near the plug. Compare this number to the wattage rating of the portable generator. The generator needs to produce an equal or higher amount of wattage in order to work safely. This may mean sacrificing the use of an air conditioner in favor of a refrigerator. A bigger portable generator with a higher wattage rating means more available power for higher wattage tools and appliances.

Surge Suppression

Filed under: Uncategorized — Tags: , , , , , , — Administrator @ 4:18 am

surge-protectorThe need for surge protection products has increased dramatically and is expected to grow in the years ahead. Today’s businesses rely on computers and computer systems to support transaction activities essential to the success of the business. If the computer is down, most activities stop. The business comes to a grinding halt. Power irregularities such as surges and spikes create performance problems for the systems handling essential transactions and sensitive information.

How often is a house directly hit by lightning? Not very often, but strikes in the proximity of a home can cause surges in the electrical, telephone or cable television lines that can cause severe damage to electronics. A nearby lightning strike isn’t the only risk. Downed power lines, the cycling on and off of equipment at a nearby factory and even the cycling on and off of appliances in the house can cause damaging surges.

Notable changes to the Seattle Electrical code (SEC)

Filed under: Uncategorized — Tags: , , , , — Administrator @ 3:22 am

car-charger-cord-capElectric Vehicle Charging Systems: The SEC has established provisions for the future installation of electric vehicle charging equipment. Article 625.27 has been added to establish requirements for physical space in the service equipment to install a future disconnect for electric vehicle charging. The article also requires pre-planning where the panels and charging outlets would be installed. Consideration should also be given to routing raceways to the required parking areas. Article 220.57 identifies the additional electric vehicle load calculations to be added to the service demand loads. It is anticipated at this time that electric vehicles will be available in the Seattle area as early as the fall of 2010.

Selective coordination as required by Articles 620.62, 700.27, 701.18, and 708.54 has been amended by the SEC. Fault current calculations provided by a licensed electrical engineer may be selectively coordinated for faults with a duration of 0.1 seconds or longer. The calculations will be required to be wet stamped by a licensed Washington State electrical engineer. All other calculations will be required to be calculated to infinity and will not be permitted to utilize adjustable trip breakers to achieve selective coordination.

Afci breakers need testing monthly

Filed under: Uncategorized — Tags: , , , , — Administrator @ 10:32 pm

panel1

Arc fault circuit interrupters (AFCI) are fairly new in the electrical industry. Similar to ground fault circuit interrupters (GFCI), they are designed to shut off the electricity to a circuit when a specific type of problem is detected. AFCIs are specifically designed to detect certain arcing conditions, which is a common cause of electrical fires in our homes. They are placed in the electric panel.
As with the GFCI outlets in our kitchens and bathrooms, the AFCI breakers in the electric panel also should be tested monthly to ensure that they are working properly. Each AFCI breaker is labeled and has a test button on it. AFCI circuit breakers typically protect all the electrical outlets and switches in the bedrooms.

If AFCI breakers trip regularly, consult a qualified electrician immediately to determine why the tripping is occurring.

Today’s Safety Tip

Filed under: Uncategorized — Tags: , , , , — Administrator @ 11:06 pm

electric-outletWater and electricity are a deadly combination. Never use an electric appliance in or around your bathtub, shower or any other wet surface.
• Never touch an electric cord or appliance with wet hands.
• Ground fault circuit interrupters (GFCI) are required for outdoor outlets and those in crawl spaces, bathrooms, garages and near your kitchen sink.
• Don’t overload your electric outlets with too many plugs.
• Only use extension cords at their recommended rating, and never string two together or place an extension cord underneath a rug.
• Cover your outlets with plastic safety caps if you have small children around.
• Never insert a metal object into an appliance. (That goes for your toaster, too!)
• Worn cords can cause shorts, shocks and fires. Don’t use them.
• Don’t carry an appliance by the cord.
• When you unplug an appliance, pull the plug head, not the cord.
• If an appliance smokes, sparks or shocks you, unplug it and have it repaired before you use it again.
• If an appliance catches fire, unplug it, remove the fuse or switch the breaker to “off.” If you can’t control the fire, evacuate the premises and call 911.
• Use a licensed electrician for your home improvement projects

Play it safe!

house-fireAccording to the NFPA “National Fire Protection Association” ignoring your home’s electrical system can be a costly mistake.

Our lives literally depend on the safe use of electricity in our homes, and often safety hazards can go unnoticed or unseen. Even what homeowners might think of as a “minor” problem can lead to a devastating fire. In fact, electricity is a leading cause of home fires in the U.S.

Each year fires that start in electrical systems or lighting equipment
• damage more than 24, 000 homes
• kill 320 people
• injure 830 more

With today’s modern electrical systems you can insure that you home is safer than it ever was. However some older homes still have dangerous electrical systems such as knob and tube wiring and may have electrical panels like Federal pacific that have a tendency not to trip under a specified load and cause a potential fire. It is important for you to have your electrical system checked out by your local electrician to insure that your home is safe and operating under the parameters set in the National electrical code. Play it safe and have your home inspected it just may save your life.

Hello world!

Filed under: Uncategorized — Tags: , — Administrator @ 3:21 pm

SEATTLE – Seattle is plugged into part of $100 million in federal stimulus money to promote electric cars and hundreds of city residents will soon get their own charging stations.

I think we are moving in the right direction getting ourselves off of crude will be a tough battle but a battle which I will fight for. One of the problems is that 70% of Americas electricity comes from coal while the balance is made up of hydro and nuclear energy. In closing it may seem like a catch 22 at first but with a little more time electric cars will be the future.
