"ELI was wonderful! He arrived on time, was friendly, thorough and quick. What really impressed me was ELI'S attention to the little details--he made sure no water, garbage got loose under the counter, used a mat to protect my floor/inside counter, cleaned up everything--even my sink--when he was done and, finally, put everything back under the counter where it was before he came! Above and beyond customer service! I will recommend AAA who anyone who needs drains unplugged! Also I like the company and especially the SERVICE so much, I'm meeting with a tech for another job--electrical this time. THANK YOU, ELI for your time, service and patience with my speech! much appreciated!"

Electrical FAQs, answered by experts

Yes, many professionals offer wiring upgrades as part of their services, including upgrades to support VoIP, fiber optic, or high-speed internet connections. It is recommended to confirm the specifics with your contractor.

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.

That depends on your setup. If a circuit breaker already has GFCI protection, then everything connected to that specific circuit is being monitored. You don’t need additional GFCI outlets on that breaker.

However, if the breaker is not GFCI, then you should have GFCI receptacles for at-risk outlets nearby water sources, because they are not receiving protection. Breakers in a breaker box can vary between GFCI and non-GFCI. Look for GFCI labels on the breaker or try to find the breaker model number to look it up if you aren’t sure.

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.

Old electrical systems may have more problems than newer ones. In some cases, like if your home has aluminum wiring, it may be necessary to update your electrical system. You should also update your home’s wiring if it still has knob and tube wiring, which is considered dangerous by modern building standards. If that applies to you, get in touch with an electrical professional near you to obtain a quote.
