"They combined two electrical boxes into one and had to move an outlet to slow for a longer panel. The guy did the work while my disabled husband was home (he was unable to climb stairs and inspect the completed work). I came home after the guy left and had to move the old electrical panel that was sitting in front of my garage door. All the rest of the garbage was sitting in my garage. I was not happy, he told my husband he could not fit the trash in his car. When I looked at the completed job I saw he had retired the outlet and had a cord across the front of the panel box so it couldn’t be opened unless I unplugged the cord. What?!! And he also left his own personal trash in the basement. I was very upset and called the rep that had originally come to the house and he sent the same guy out the next day to fix it. I asked him to please take the old panel box and other trash he left and he said he didn’t have room in his car to take it. I was not happy with this company and would not recommend."

"I had previously gotten a quote from *****busters that was 3x the amount that AIT quoted. I felt better about going with AIT though because of the service - Artur and his team were confident in their service and the products they sell and they guaranteed that they would stand by me until my home networking issues were resolved. Months later, my entire 4500 sqft home receives flawlessly smooth internet/streaming without anymore blank spots. I cannot recommend AIT enough to those looking for affordable and quality residential networking diagnosis/installation."

"I have to gush about Cris. He's one of these rare pros that you should hire immediately to do your electrical work. I'm certainly never looking for another electrician again. On the fundamentals: he's thorough, professional, kind, prompt, and fair in his pricing. But he also cares deeply about the quality of the work, and he does the work himself. Other pros come to him with questions. He's the master. He may not come across as polished in the same way as pricier options, but don't let the marketing fool you. If you want the job done expertly, go with Cris."

Electrical questions, answered by experts

Often, you can add extra breakers to an electrical panel. A new breaker can help with new appliance needs, and it’s a common solution when finishing an attic or basement. However, adding extra breakers can’t bring in more amps to your house, so you still need enough amp service to power everything in total. 

Yes, a light switch still has power even when switched off. Switches only interrupt or continue the flow of electricity into a fixture or outlet; they do not shut off the power flowing into the wire. The only way to shut off power in a light switch is to turn off the power at the circuit breaker.

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).

It's possible to get power from an outlet for a light switch. However, you must install additional wiring to get current from the outlet to the switch and from the switch to the load it will control. Also, you must ensure that the outlet's electrical circuit can accommodate the additional demand. 

Yes, states and local governments can have additional building codes that address kitchen outlets. In most cases, these kitchen outlet codes simply refer to the NEC. However, states or local municipalities can have separate requirements for electrician licensing, such as requiring a permit to make big changes, and other details.
