"Had an electrician out to give me an estimate on replacing my electrical panel. Decided against replacing it because that wouldn't have solved my issue. My house was built in the 60's so it needs all new wiring. I just had him show me which outlets were on each of the channels so that I could spread out my devices that needed a lot of power, specifically my space heaters."

"I called several electrical companies and their timeframe was about a week out I found JLP electrical services did same-day service. They were able to help me with my installation of a attic fan. These hot days definitely needed to cool my house down and he was able to finish the project in a promptly time manner. Highly recommend JLP electrical services. ⚡️⚡️⚡️⚡️⚡️⚡️⚡️⚡️"

Electrical questions, answered by experts

While most electrical items can be plugged into a GFCI outlet, some appliances with internal or stationary motors, such as refrigerators, vent fans, and fluorescent lighting, can cause nuisance tripping. This happens because they experience a small, normal amount of current leakage, which can cause the GFCI to trip even when the appliance is working correctly. Although this is not a safety hazard, it can be inconvenient and may cause the GFCI outlet to wear out faster. For this reason, it is often better to plug these types of appliances into a standard outlet. Additionally, electrical circuits over 100 feet long can sometimes cause tripping. Some appliances, like hair dryers, have their own built-in GFCI protection, so connecting them to a standard outlet is fine.

No, it doesn’t matter which of the two wires goes on each of the two switch terminals. Just be sure to put the ground wire in the correct terminal. The ground wire is either green, bare copper, or green with a yellow stripe. The other wires are hot wires and are typically black. They can be used interchangeably.

While not always necessary, wiring your circuit breaker in a certain way can ease both the installation process and use afterward. For starters, you’ll need to install the electrical panel so that the main service knockout aligns with the cable conduit. If they aren’t aligned, you may not have sufficient working space to finish running the wires. Using cable trays, on the other hand, gives you a bit more freedom to and flexibility in where and which direction you install the wires. At the end of the day, the power flow will be the same whether the cords run up or down.

Grounded electrical outlets are usually three-pronged. You can also look for a grounding clip in your outlet boxes or use a circuit tester. If you’re unsure, consult a suitably qualified electrician regarding your home's electrical safety.

A duplex outlet simply means that the receptacle has two plug-in outlets for two plugs. It’s a common design choice for homes. The two outlets should be wired identically during installation so the hot side is the same for both.
