"Electrical in an older home can be complicated. We had several people give outrageous estimates or never show up to do the work. Stapleford electric was prompt in providing an estimate and completed the work with quality. The cost for installing a new outlet and bracing for a large, heavy chandelier was fixed cost and other work was a time and materials rate. Both were reasonable and they knew what they were doing with the old style wiring. We had an additional expense to get plaster repaired separately but that would have been the case no matter who did the electrical work - they referred us to a master plasterer which was great. I have no reservations to recommend or use Stapleford again."

Electrical questions, answered by experts

No, because amps and volts measure very different things. However, you can use basic equations to find amps or volts by using data about one of the measurements to calculate the other.

The life expectancy of a circuit breaker is 30 to 40 years. However, how long your circuit breaker lasts depends on the condition of your electrical equipment, the amperage, your electrical consumption, and more. A breaker box that frequently trips from overload will last much shorter than a breaker box with the proper amperage for the number of devices and appliances in use. If your circuit breaker trips frequently, and you have also increased your electrical consumption, it may be worth upgrading your electrical panel to extend your electrical system’s lifespan—and save you the hassle of frequent power trips.

Yes, the National Electric Code (NEC) requires at least one GFCI outlet in each sectioned-off portion of an unfinished basement, partly to ensure a power source is available for a sump pump in case of flooding. If you install multiple outlets in your unfinished basement, all of them must be GFCI-protected. For finished basements, standard outlets are generally permitted, but at least one GFCI outlet is still required per circuit. Keep in mind that local municipalities may have additional codes, so it's best to consult a licensed electrician to ensure your home is fully compliant.

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).

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.
