Electrical FAQs, answered by experts

You can make a pigtail with either thermoplastic high-heat-resistant nylon-coated (THHN) wire or non-metallic (NM) cable, often referred to as “Romex.” Each pigtail requires a neutral wire, a ground wire, and a live wire. The gauge of your pigtail wires must match the gauge of those on the device. 

The NEC prohibits the installation of electrical panels within clothing closets. Closets are filled with flammable items like clothing, mothballs, shoe polish, plastic containers, and exposed light bulbs. If the panel develops a small electrical fire, it won’t take long to bloom into a real disaster. If you have an electrical panel in one of your home’s closets, move it as soon as possible with the help of a professional electrician.

People who have experienced blown fuse have occasionally tried to fix the problem by placing copper pennies in the fuse box. While they are good conductors of electricity and can seemingly “fix” the issue,  they don’t protect against short circuits or fires. Putting pennies in a fuse box is dangerous—the best solution is to call a professional electrician to fix the problem.

Light switches can last for decades when installed and maintained correctly. Improper wiring, heavy wear and tear, or too much wattage draw can cause light switch failure long before the expected end of a light switch’s life. Light switches that are hot to the touch, making a buzzing noise, or failing to work consistently should be inspected to find and repair the underlying cause.

Yes, it's possible to have electrical receptacles and overhead lights on the same circuit. The reason is that lights typically use much less power than large appliances, so combining them won't overload your circuit. By doing this, you can distribute the power consumption throughout the breakers in your panel more efficiently, which can be helpful if you have a lot of different electrical devices in your home.
