"This is definitely the guy to hire if you need any electrical work done! He was kind and exceptionally professional. It was supposed to be a simple ceiling fan replacement. However, Larry found a serious problem with my wiring that I'm blessed didn't actually cause a fire in my home. He showed me the problem and fixed it even though that really should have been a separate call. I am over the top pleased with the service and work performance. I HIGHLY recommend Top Notch Electrical and Larry!!! 5 STARS!!!"

"Contacted Randall for getting power to an external garage. He gave his professional opinion to run power from the pole to the garage instead of from the house. Price was reasonable. He was professional and completed the job all while keeping me informed. Recommend him to anyone who needs electrical work done. Being a veteran owned business is a plus."

Electrical questions, answered by experts

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).

When installing an outdoor outlet, it's important to proceed with caution. Unless you have the necessary training and licensure, it's not recommended to attempt this DIY. First, choose a suitable location. Make sure that the area can accommodate the outlet without overloading the circuit. You'll also need to ensure that your project complies with building codes. Next, turn off the power to the circuit, then install and wire the outlet according to the manufacturer's instructions. Once the outlet is in place, test it. Lastly, be sure to use a cover that will protect it from moisture and other weather-related damage.

Common signs of faulty electrical wiring include frequent circuit breaker trips, flickering or dimming lights, burning smells near an outlet, buzzing or humming sounds, electrical shocks or tingles when handling outlets of appliances, and hot or discolored outlet switches. If you notice one or more of these signs, hire a licensed electrician for an average cost of $50 to $100 per hour to diagnose and make necessary repairs.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

The cost of fixing faulty wiring depends on the type of repair required. Replacing an electrical service line, for example, can cost up to $500. Rewiring an entire house will cost at least several thousand dollars. Replacing old wiring like knob and tube wiring will be even more expensive, but fortunately that kind of outdated wiring is fairly rare. Always get an estimate from a reliable electrician to learn the cost details.
