"I'm glad we hired A and Z. Barry Goldstein gave us a call and come to our residence to look at the work needed. Barry is a great and sincere person and we enjoy the small talk but got to business. We were in need of GFCI electric switches in the kitchen, bathroom, and other areas. Plus, we need new electrical outlets in our closets in both bedrooms and have the pulley taken out, and ad a fixture on the outside of the closet. We also had a hazard with the powerline where the clamps that are attached to the outside wall of the house were hanging out. Plus the kitchen exhaust fan and the ceiling fan needed to be installed and they did. The crew explained what is expected in the process and the price. They placed it back to her tight in order for us to get COMED to fix the wiring. They came and fixed the job and did it cleanly and professionally. The crew was great to talk to and we felt they value customer service no matter what the job. We like their overall work and are responsive. I recommend A to Z for anyone looking for small to big jobs. Great job they did."

"J&M Electric was great! They updated my electric panel box, fixed some light switches, and installed a beautiful chandelier/ceiling fan and new light fixtures outside. The whole team was professional and courteous. The fees for all the work done was fare! I recommend them to anyone needing electrical work done and will use them again when the need arises!"

Electrical questions, answered by experts

The lifespan of an average breaker box is 25 to 40 years, depending on the type and electrical events that occur in your home. Frequent power outages or surges can cause the breaker box’s lifespan to shorten. Maintain this essential electrical component by avoiding turning it off and inspecting it regularly for signs of damage.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

That depends on your setup. If a circuit breaker already has GFCI protection, then everything connected to that specific circuit is being monitored. You don’t need additional GFCI outlets on that breaker.

However, if the breaker is not GFCI, then you should have GFCI receptacles for at-risk outlets nearby water sources, because they are not receiving protection. Breakers in a breaker box can vary between GFCI and non-GFCI. Look for GFCI labels on the breaker or try to find the breaker model number to look it up if you aren’t sure.

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.
