"Proprietor is very personable, thorough, and sincere. He took the time to review all options available for the job. He also spent time helping me to understand proper use of set up as well as operation of the portable generator. He also gave me insight to yearly maintenance needs and reasons for that maintenance. His work was done quickly, completely and area was left clean. I would recommend Chad Woods Electric to anyone looking for a great electrical contractor"

"Paul arrived on time, quickly identified a workable solution to my electrical need. He noted equipment and wiring I already had installed and used that knowledge to give me an estimate that was much less than previous estimates. He is very knowledgeable, got the job done quickly and I would heartily recommend him for any electrical work."

"Michael has been wonderful from start to finish. Even when I was experiencing difficulties with the pool company to come out and install, that put him on hold from getting his electrical part done. Michael was on stand by and ready to come out when I needed him. Super professional, gets right back to you with any questions/concerns, on time and very patient. Will be hiring for future electrical projects!!!"

"Dave was great! Top quality work at a fair price. I needed a degraded riser cable that feeds the meter box outside the house replaced. Another company gave me a ridiculous quite which included current code updates that said I needed. My town electrical inspector said that none of those were required for a simple riser cable replacement. I highly recommend Lanzillo Electric!"

Electrical questions, answered by experts

No, it doesn’t matter which of the two wires goes on each of the two switch terminals. Just be sure to put the ground wire in the correct terminal. The ground wire is either green, bare copper, or green with a yellow stripe. The other wires are hot wires and are typically black. They can be used interchangeably.

If only half of your outlet works, there are usually two possible causes: faulty wiring or a half-hot outlet. The first thing you'll want to do is check the circuit breaker panel to ensure that it's not tripped. If your circuit breaker isn't tripped, turn off the electricity and inspect the wiring to see if anything has come loose or corroded. 

If you have a half-hot outlet, it means half of the outlet is controlled by a switch somewhere on the same circuit, which should be nearby. This is an intentional electrical design commonly found in rooms without overhead lights.

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).

Yes—if a breaker is old or damaged, it might not be able to detect power surges or electrical overload. If that happens, the breaker won’t trip. Instead, it will begin to overheat, putting your electrical system at risk of fire or total electrical failure. Circuit breakers don’t last forever, so you can proactively replace old or damaged breakers before they stop working.

Three-way switches work in pairs, allowing an operator to control a single light or series of lights from two separate switch locations. Most often, a three-way switch controls a light or light series in a single room.
