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).

Yes, you can use a dimmer switch with an LED fixture, but it must be a dimmer that is compatible with LEDs. Check the manufacturer’s information to ensure the dimmer works with LEDs, as not all dimmers are compatible with them. Many smart light switches accept LEDs, but be sure to read the details on the packaging.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Yes, many remodels include electrical upgrades for lighting, outlets, or charging stations. Confirm with your contractor.

Outlets do wear out, usually within 15-25 years, but they can fail even sooner than that —sometimes in a matter of years. If your plugs always slide out after you put them in, this is a sign your outlets need to be replaced. Additionally, if your outlets are damaged, cracked, discolored, or regularly tripping the circuit breaker, they may be at the end of their life.
