Electrical questions, answered by experts

Yes, you must use the proper wire nut that fits your wire gauge. Using a wire nut that’s too big or too small can cause your connection to fail, short circuit, or disconnect entirely. Ensuring that you have the proper wire nut size will guarantee that your connection lasts as long as possible.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

You're in luck, because replacing a breaker panel is not a regular occurrence that most homeowners have to worry about. Electrical breaker panels last 25 to 40 years, assuming you properly maintain your system and conduct annual inspections. Factors like load demand and exposure to the elements slightly reduce a breaker panel’s lifespan.

A home warranty usually covers electrical wiring work, depending on your specific plan. Most home warranty plans cover repairs for major appliances and home systems, including failure due to wear and tear. Home warranties aren’t as common as homeowners insurance, but they are more likely to cover old wiring.

While most electrical items can be plugged into a GFCI outlet, some appliances with internal or stationary motors, such as refrigerators, vent fans, and fluorescent lighting, can cause nuisance tripping. This happens because they experience a small, normal amount of current leakage, which can cause the GFCI to trip even when the appliance is working correctly. Although this is not a safety hazard, it can be inconvenient and may cause the GFCI outlet to wear out faster. For this reason, it is often better to plug these types of appliances into a standard outlet. Additionally, electrical circuits over 100 feet long can sometimes cause tripping. Some appliances, like hair dryers, have their own built-in GFCI protection, so connecting them to a standard outlet is fine.
