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."

"EXCEPTIONAL SERVICE & EXPERIENCE FROM START TO FINISH. Let me start with the fact that I had no idea as to what I was getting into when I purchased an EV. The team at Kapital Electric helped to set me up with a home charger (at no cost to me). Donald at Kapital Electric met with me to discuss to process and provided me all the necessary paperwork to get the ball rolling. In no time, the charger was being installed. The staff who came to install were professional, work was neat and completed in the specified time. If you're looking for exceptional service & experience from start to finish, give Kapital Electric a call!"

Electrical questions, answered by experts

If you have a garage heater that is 1,500 watts or more, it will need its own breaker. As a good rule of thumb, no appliance should exceed 1,500 watts per outlet for best outcomes. Consult a local garage heating service to determine the power needs for your outdoor or indoor space.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.

The Occupational Safety and Home Administration (OSHA) requires an electrical panel to have a minimum of three feet (36 inches) of room from the front of the panel to the closest obstacle. In this case, the word obstacle refers to nearly everything, including walls, machines, and other fixed objects. Additionally, panels require at least 6½ feet of headroom in the area directly in front of the fixture. These requirements help ensure safe use of the panel and allow electricians plenty of room to work.

Yes, an AFCI (arc fault circuit interrupter) outlet also has line and load terminals, although it uses different technology than a GFCI and offers a different kind of protection. AFCIs monitor for internal arc faults, a type of wiring problem that can start an electrical fire.
