Electrical questions, answered by experts

According to the National Electrical Code (NEC), GFCI outlets should be installed in wet or damp locations where they might be splashed with water or other liquids. This is to protect against ground faults, which are more common around water. Specific areas that require GFCI outlets include kitchens (especially near counters), bathrooms, laundry rooms, basements, garages, and all outdoor receptacles. Depending on local electrical codes, you may need at least one GFCI outlet in these rooms, or every outlet in the area may need to be GFCI protected.

The common, marked as COM or C, is one of the terminals found in your light switch. It houses the live wire that supplies the input voltage. The other terminals, marked as L1 or L2, are the outputs to the light fixtures. Depending on if you have a one-way or two-way switch, you’ll either have just an L1 terminal or both an L1 and L2 terminal.

There are several tools available to help prevent electrical fires. First, ensure that you have GFCI outlets installed in necessary areas, along with an AFCI, which is a circuit breaker that can help prevent arc-faults. Investing in surge protectors is also wise, as they can safeguard your appliances and other items against power surges that may overload your outlet and cause sparking.

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).

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.
