While washers and dryers do not require a GFCI (ground fault circuit interrupter) outlet to function properly, electrical codes often mandate their use for safety. The National Electrical Code (NEC) requires GFCI protection for all outlets within six feet of a water source. This means a washer and dryer must be plugged into a GFCI outlet if they are installed in locations like a laundry room, utility room, garage, or basement. In other areas without a nearby water source, there is no specific requirement, but using a GFCI outlet is still recommended for extra peace of mind. It is always best to consult your local codes and regulations to ensure compliance and safety.

Poorly designed and incorrectly installed outlets can create an electrical fire hazard, as do some phone chargers and adapters that plug into these outlets. However, most outlets are perfectly safe as long as they remain in working condition. Keep an eye on what you are plugging into the outlet and stay alert for signs of outlet malfunction, like sparks, burning smell, or frequent circuit tripping.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

Choosing between 12- or 14-gauge wire for your house depends on the electrical requirements of the circuit. A 12-gauge wire is thicker and can handle more power, making it better suited for devices such as kitchen appliances, air conditioning units, or electric heaters.

A 14-gauge wire is thinner and can handle less electrical current than a 12-gauge wire. It's ideal for circuits with lower power requirements, such as lighting or general-purpose outlets in bedrooms or living rooms.
