"Scott did an excellent job for us. We needed an EV charger installed and a few other things done. He came by, sized up the job and gave us an estimate. In a few days he showed up ready work. He installed the EV charger, re[laced 4 thrmostats, and fixed a doorbell. All went well. His price was reasonable. He worked quickly and efficiently and got everytjing right the first time. I highly recommenr Moses Electric and would glady hire Scott for future electrical jobs."

Electrical questions, answered by experts

Depending on complexity and materials, costs range from $150 to $500 per fixture.

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.

You can add an electrical outlet outside by sending a wire through the wall from an existing interior outlet. Without having to open up walls, you can thread a new electrical cable from the existing outlet through the wall and to the exterior. You’ll need to cut a hole in the siding to place your new outlet. Ensure that your outdoor outlet is a GFCI outlet (ground fault circuit interrupter outlet) per the National Electrical Code. It’s best to hire an electrician to add an outdoor outlet unless you have previous electrical experience.

A faulty light switch can trip a breaker due to circuit overload or a short circuit. A faulty light switch may not always trip a breaker, so don’t use that as your only sign that something’s wrong. Always investigate the cause of a switch that isn’t working properly, feels hot to the touch, or is making unusual noises.

Local electricians with experience in your area understand the local building codes, which is very important when doing new electrical work. They also have experience with the kind of electrical problems homes in your location may have, and even the components that were used in the original construction, which leads them to make faster and better decisions.
