"40 X 32ft shop. 27 conduit drops to include two 220 drops for Welder and Mini Split Technicians were very courteous, knowledgeable and professional. They answered all my questions thoroughly. After the install, they briefed on the electrical panel. Organized to perfection. I would not hesitate to hire this business again. Highly recommended. Thanks again to Mike and Chadwick, you made the experience positive. Brandon"

"I recently faced an issue with my refrigerator not cooling correctly, so I reached out to Appliance Tech of East Texas LLC for assistance. Throughout the entire process, I was thoroughly impressed with their professionalism and expertise, from the first phone call to the repair's completion. The technician, who I believe was named Nathan, arrived punctually, was amiable and knowledgeable, and quickly diagnosed the problem. He clearly explained the issue to me and provided a detailed estimate of the repair costs before proceeding. The repair was executed efficiently, and the technician made sure that everything was working correctly before leaving. Overall, I am exceedingly pleased with the service I received from Appliance Tech of East Texas LLC, and I would highly recommend them to anyone who requires appliance repair services."

Electrical FAQs, answered by experts

Yes, you must use the proper wire nut that fits your wire gauge. Using a wire nut that’s too big or too small can cause your connection to fail, short circuit, or disconnect entirely. Ensuring that you have the proper wire nut size will guarantee that your connection lasts as long as possible.

If you’re interested in exploring other avenues to completely upgrade your electrical panel, it’s also possible to add a sub-panel, which is a smaller panel that connects to what you currently have in place. This way, you can add additional circuits without having to swap out your main panel.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Although homeowners can turn off a breaker, it’s vital to follow safety precautions when doing so to prevent serious and potentially fatal injuries. For instance, you want to ensure there is no water on the floor when you touch the breaker and wear protective gear such as safety glasses. Anytime you deal with anything electrical, it’s always best to be as safe as possible.

The size of your home will help determine the size of your electrical panel. Usually, the decision comes down to a 100-amp electrical panel versus a 200-amp panel. Smaller homes, especially those without an HVAC system, may be able to get by with a 100-amp panel. 

If you have a larger home or need to power AC, a 200-amp panel should be the best fit. It’s unlikely that you’ll need a larger panel than that unless you have a larger home or unique electrical needs, but an electrician can help you make the final call.
