"I had Don install four ceiling fans and two bathroom fans. While he was there, I had him do some electrical work for me. I will definitely have him come back for other projects at my home. Don was extremely friendly, professional, honest, and knowledgeable. I absolutely recommend Don Harnas."

Electrical FAQs, answered by experts

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.

No. Do not use a 14-gauge wire on a 20-amp outlet. A certified licensed electrician would know that the National Electrical Code (as per Section 240.4(D) subsection 3) requires 14-gauge wires to be used with a maximum amplitude of 15. Therefore, you should only use 12-gauge wires on 20-amp outlets.

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.

Local building codes typically require conduit around exterior wiring. Conduit protects the wire from moisture, extreme temperatures, sun exposure, and harsh weather conditions to prolong its lifespan. When a wire is worn out, it can be dangerous as the risk of electric shock or fire increases.

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.
