“Hi. I’m Craig Bryant with Bryant Electric Service, and I’ve been in business in Austin for almost 30 years now. I’ve been asked by many people a lot of different things about electrical work, and so I hope I can help with answering some of your questions as well.

OK. I’ve been asked many times about the difference between aluminum and copper wire, and the biggest difference is that copper is just a lot more stable metal than aluminum. And electricity, the biggest enemy to electricity is heat. The hotter it gets, the more important it is to have a stable metal. Aluminum is good but not as good in that in the long run over many years or decades because the instability of aluminum, when it heats up it contracts and expands. As it cools down, it contracts and heats, it expands.

So that happening over time over years and decades especially at your main service or wall plugs or something then that causes a loose connection and it starts arcing and the arc can create a fire over time. That just doesn’t occur in copper ever if it’s installed properly and it’s real tight at the beginning when it’s installed.

So the other problem with aluminum is oxidation. As they’re both exposed to air, copper oxidizes as you can see when it turns green, but it doesn’t affect the connection of the wire. Whereas aluminum, when it oxidize, it creates this crust that builds on it. And you’ve probably seen it before, but this crust can sometimes get as much as a quarter inch thick. And besides the fact that the metal is not as compatible to the heat and temperature problem. With that crust building up, it will also create a gap between the connections that can cause an arcing.

So copper is always better than aluminum and everything except price. And the main reason that it’s being used is because it’s so much cheaper.”

How many times have you observed your neighbor using a weed-whacker that is connected to a series of four or five extension cords in order to reach the far corner of the yard? Probably plenty of times. When using a series of cords, be sure they are all the same rating, and check with the manufacturer or your local licensed electrical contractor to see if it is safe.

Extension cords are rated by the thickness of the wires inside using a standard known as AWG (American Wire Gauge).

A large amount of the calls we go out on are for lighting fixture replacement/changes.  A lot of the customers say “I usually do this myself,” but I don’t have time to take care of this right now.  Another common quote we hear is “We have been working on this all weekend, and can’t get it to work.”  Last but not least, a favorite quote of mine that I hear is “I am so tired of this outdated looking lighting that exists in my home.  Can you please bring it up to date?”  Usually this is where I chuckle and say “Twitter, Google Plus.

Some winters pass quietly, others live in infamy. As one of the latter, this winter many of you may have had to resort to a “by any means necessary” approach to staying warm. Hopefully you had carbon monoxide detectors in your home to help you make it through safely. Manage without them? You might want to seriously consider the addition of these useful appliances.

Who needs a carbon monoxide detector? Anyone using any type of combustion heating such as wood stoves, fireplaces of any kind, gas and oil furnaces, in addition to gas appliances such as water heaters, stoves, and more. The incomplete combustion of fossil fuels such as coal, wood, charcoal, kerosene, propane, and natural gas used to power these items naturally produces CO (carbon monoxide) fumes. If you made it through this winter without a detector – great! But don’t push your luck. CO is the number one cause of poisoning deaths in the U.S. The Consumer Products Safety Commission (CPSC) reports 200 people are killed each year from accidental CO poisoning, with another 5,000 injured. Chimneys get clogged, appliances malfunction or suffer venting issues, and today’s airtight homes increase the chance of CO accumulation. In short, stuff happens – be prepared!

We love carbon monoxide detectors. Why?

How they work Though design varies slightly by model, carbon monoxide detectors use a CO gas sensor to identify and measure the concentration of carbon monoxide in your home in parts per million (ppm). When dangerous levels are detected, an electronic pulse is sent to activate the alarm – the higher the levels, the faster the response.

Are your carbon monoxide detectors safely installed?
