"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."

"Wallace provided outstanding electrical service from start to finish. He arrived punctually and maintained a professional demeanor throughout the project. His technical expertise was evident as he successfully installed three light fixtures, replaced one outlet, and expertly repaired another outlet. What truly set Wallace apart was his attention to detail and respect for our property. He cleaned up thoroughly as he worked, leaving no mess behind. Additionally, he was very considerate of our schedule, working efficiently without disrupting our day. I highly recommend Wallace for any electrical needs. His combination of technical skill, professionalism, and customer service makes him a standout contractor"

Electrical questions, answered by experts

Modern homes have a lot of devices and appliances running at once. That means there are many different wires and cables throughout the house. Service entrance conductors (also known as service entrance cables or service feed wires) connect the external weatherhead for the utility pole to the circuit breaker box. This is your home’s connection to your local power grid.

Unless you have prior electrical experience, it’s best to hire a professional to install your new thermostat for you. Improper installation can damage wiring, lead to a blown fuse, and more.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

Inverter generators are designed to turn on the engine when your appliances demand more energy. This is in contrast to running at full capacity as soon as they’re turned on, like a standard portable generator does. So long as the wattage rating is high enough, an inverter can power a refrigerator just as well as a traditional generator.

Yes, a hot or overheating outlet is a fire hazard and can cause a fire. An outlet becoming hot indicates an electrical problem, such as an overloaded circuit, loose connections, or a faulty component. The heat from these issues can ignite nearby flammable materials like curtains or furniture. If you notice an outlet is hot to the touch, turn off the power at the circuit breaker, unplug any connected devices, and consult a qualified electrician. If a fire does start, use a Class C fire extinguisher or baking soda to suppress it, or evacuate immediately and call the fire department.
