"We highly recommend U.S. Energy Solutions...Mom and dad had some unforeseen electrical issues that needed to be fixed in their kitchen due to an inspection review before selling their home. I went to Angie's List put in a request for suggestion and U.S. Energy Solutions got right back to me. We set up and appointment! Electrician was prompt, courteous, professional and friendly. He diagnosed the issue straight away, took the time to show us and explain the problem. His confident approach to the problem was reassuring and was fixed quickly! All the way around a great experience!!"

"We wanted to update our dated kitchen, and needed to upgrade multiple aspects of the electrical. We called Current Electric on recommendation from a friend who had used their services in the past. Through the entire process of replacing the old lighting with more modern fixtures, installing an outlet in the pantry for our toaster oven to free up counter space, and adding a switch under the sink for the new garbage disposal we had plumbers install beforehand, these contractors were friendly, professional and knowledgable. They worked in a timely manner that allowed us to stress less about the project and enjoy the new look and function of our updated kitchen. Everything works just how we had hoped and we intend to use their services for any future electrical work."

"The actual name for the electrical service provider is Tri-State Electrical. Chris did an excellent job of installing the bathroom exhaust fan and he was very professional. I thought the company would send me a receipt for paying for the installation after they cashed my check. I did not receive a receipt."

Electrical questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

GFCI outlets should be clearly labeled with LINE and LOAD labels, with arrows leading to the proper terminals. The line terminals are typically at the top, and the load terminals are typically at the bottom.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

The number of outlets and lights you can safely run on a single circuit depends on the circuit's amperage and local electrical codes. A general rule is to allow one outlet or light fixture per 1.5 amps, keeping the total load under 80% of the circuit breaker's capacity. For example, a 15-amp circuit can typically support up to eight outlets or lights, while a 20-amp circuit can accommodate up to ten. Always consider the combined power usage of all connected devices and fixtures to prevent overloading. For specific guidelines and to ensure safety, it is best to consult local electrical codes or a licensed electrician.

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.
