"Mr Electric was quite reasonable in price. And he did find the problem quickly and he had it fixed within reasonable time. Mr Electric was fantastic and he absolutely knew what he was doing.. . He checked out all outlets and lights as he followed it thru until he found the problem that blew my electric in one half my home. Thank You ever so much!"

"Tony with Covenant Electric always made time for my questions and concerns! We were able to text (which I prefer!) and call to troubleshoot. He even took time on the weekend for me. 10/10 would recommend. Very friendly, very professional. Will always use him for any future electrical needs."

"This company is obviously nationwide and hires local contractors.  I trusted Agies List that all contractors are licensed, bonded and have background checks.  This person was a handyman and not qualified to wall mount, conceal wires, add electrical outlet.  He  spend five hours in my home, for a job that should have taken two hours and left the area in a disaster.  The TV was hung close to the ceiling, the wires were hanging down from the TV, and the receiver was sitting on top of a plaster box because the cord was too short.  He was obviously not qualified to install TV wall mounts.  I have photos.    As soon as he left, I called Best Buy Geek Squad.  They were able to come out the next day and mount the TV professionally.  I have used the geek squad in Virginia and they are highly qualified.  They charge more than this nationwide company but you get what you pay for.  I called Angies List the day after the disaster and said i did not want to rate this company but I wanted to talk to a manager. No one called me to apologize. I have cancelled my membership.  Do not use this company unless you can be assured that the local contractor is qualified and is licensed.  You should never let anyone into your home that has not had background checks.

Electrical FAQs, answered by experts

Before the widespread use of PVC, affixing a ground wire to plumbing pipes was generally considered to be an acceptable workaround. Nowadays, not so much. There are plenty of nonmetallic water pipes and fittings out there, so any ground previously provided by the metallic piping would be interrupted in these cases, which is dangerous.

GFCI stands for ground fault circuit interrupter, which means it has the ability to detect a ground fault and shut the circuit down before it creates hazards. General breakers may also do that because ground faults can cause overloads, but they’re more focused on amp overloads from any cause. GFCIs are often installed in specific outlets, but breakers can come with GFCI capabilities built in for broader ground fault protection.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

Yes, a dead outlet can be dangerous and may cause a fire. The lack of power can be due to a hazardous electrical issue that poses a fire risk. If you notice a burning smell, discoloration, or sparks from a non-working outlet, it is a serious issue. It is vital to have a professional electrician investigate and fix the problem as soon as possible.

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.
