"Jeremy sent his colleague Austin to my home a day after I first made contact with JMP Electric to fix the cooked breakers in my electrical panel. Austin arrived at the time Jeremy had specified over the phone and promptly got to work removing and inspecting the breaker blocks. In under 2 hours, Austin had my breaker box buttoned up and running with fresh breakers. That's some excellent service if you'd ask me. Thanks again, men! -Chris"

"I had 8 outside fixtures that had been put in without electrical boxes - just holes in the siding with wires coming through. I wanted to replace the fixtures but could not without the boxes. AWT put the boxes in and replaced the fixtures, all for a very reasonable price."

"John the owner and operator did a fantastic job. Very efficient and knowledgeable as a master electrician. Very through and thoughtful. He rewired my whole house after a flood and was willing to do a little extra for additional work I wanted done like Jacuzzi and back up generator. His prices are fair and puts the customer first. He also listened to me in a time of stress and was very encouraging. I didn't know anyone in the community and we befriend him. I would highly recommend him. My family loves him and I couldn't have chosen a better bperson for the job. We appreciate him so much. Thanks John"

Electrical questions, answered by experts

No. Blue wires and black wires are different. Even though both are used as hot wires, they serve different functions. Black wires are far more common in residential properties. They are always hot, can be positive or negative, and usually carry electricity from a power source to an outlet. Blue wires have a specialized usage in residential properties, generally as traveler wires, and are more common in commercial properties.

When selecting a pool heater, it’s important to think not just about the cost of the unit itself but also about how much it costs to run. Expect to pay about $100 per month to run a heat pump pool heater. A natural gas heater will cost twice that amount, while an electric pool heater costs about $250 a month.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

No, because amps and volts measure very different things. However, you can use basic equations to find amps or volts by using data about one of the measurements to calculate the other.

An AC disconnect, also known as a switch box or fuse box, is a safety switch that allows the AC’s electrical supply to be turned off from the outside, usually done by a mechanical contractor coming to work on your unit. The box is protected from the weather by a cover or may be designed as a pull-out unit. Your local code determines where the AC disconnect must be mounted, but it's usually close to your outdoor AC unit.
