"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."

"WB Lightning Rods did an excellent job installing lightening rods on our home. The owner stayed onsite the entire time to supervise the work. He took extra care to plan the rod and cable placement to ensure the proper protection and retain the aesthetics of our home. His crew were knowledgeable, polite, neat and efficient. We could not be more pleased with the results."

Electrical FAQs, answered by experts

Rewiring projects cost anywhere between $1,500 and $10,000 on average, depending on the complexity and the size of the rewiring. You can anticipate spending between $2 and $4 per square foot of wire, including labor and materials. Wire material ranges from $0.25 to $1.60 per linear foot.

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.

Compared to amps, volts, and watts, ohms are a different kind of measurement, though also very common. Ohms show the resistance of materials like wiring: How much they impede the flow of electrons. The reason household wiring is usually copper or aluminum is that these materials are affordable and also have lower ohms, which means low resistance/high conductivity.

Yes, a dead outlet can be dangerous and may cause a fire. The lack of power can be due to a hazardous electrical issue that poses a fire risk. If you notice a burning smell, discoloration, or sparks from a non-working outlet, it is a serious issue. It is vital to have a professional electrician investigate and fix the problem as soon as possible.

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.
