Q: What should not be plugged into a GFCI outlet?

• <div><p>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.</p></div>

Q: How do I maintain my electrical panel?

Q: Can I use 14-gauge wire on a 20 amp outlet?

A certified licensed electrician would know that the National Electrical Code (as per Section 240.4(D) subsection 3) requires 14-gauge wires to be used with a maximum amplitude of 15. Therefore, you should only use 12-gauge wires on 20-amp outlets.</p></div>

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire.
