"We had our electric box replaced, an outdoor light installed and an outdoor 50 amp outlet installed for our camper and electric vehicle. Greenleaf arrived on time and had everything done on time and in a professional and friend manner. Had some weather related issues but Greenleaf communicated everything and had everything rescheduled in a timely manner. Would highly recommend their service. Definitely using them for any future electrical needs."

"Lowest price among multiple quotes and significantly more attention to detail and the least visible and least intrusive installation of new wiring from the existing panel. Would definitely recommend and use Mark H. Anderson Electrical Services again!"

"From start to finish, Long Electric had our backs. We didn't have to hire sub-contractors or to obtain permits -- Long Electric took care of everything. Our go-to person in the main office, Melissa, answered all of our questions and kept us apprised of everything we needed to know. Everyone we had contact with throughout the installation project treated us with the utmost in professionalism. Not only will I call upon them for future electrical needs, I have referred Long Electric to a friend who is also interested in a whole house generator."

"I had a wonderful experience with Electrical Connections. My project ended up being much larger than I anticipated it would be and they were excellent at explaining everything and helping me understand what needed to be done. Customer service was top notch and clearly a priority for everyone I talked to from the scheduler to the owner of the company. Brian was excellent and stayed until the job was done even though it made an extra long day for him. Highly recommended!"

Electrical FAQs, answered by experts

Outlets with only two slots have no ground connection. That’s more common on very old outlets, which means it’s more likely the outlet won’t be polarized. You’ll have to closely examine the slots to see if there’s a size difference indicating polarization. Keep in mind outlets this old are usually out of code and should be replaced if you’re doing any electrical work.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

The hot wire is typically black, but it's essential to use a non-contact voltage tester to confirm the electrical wire color code before working on it. Neutral wires are typically white. It’s vital to determine which wire is carrying electrical current before proceeding with any electrical work.

When converting a standard 120-volt outlet to a 240-volt outlet, the only components you can typically reuse are the existing electrical box and the hole in the wall. Everything else—including the wiring, breaker, and receptacle—should be replaced to ensure both safety and efficiency. Appliances designed for 240 volts have different plug configurations that won’t fit into a standard 120-volt outlet, making it necessary to install a compatible 240-volt receptacle. This design helps prevent overloading or underloading the power available to any one outlet or circuit.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.
