Electrical FAQs, answered by experts

You can install a dimmer switch on almost any light as long as the switch, bulb, wiring, and wattage are compatible. Check what kind of light you have, the type of light bulb, and the total wattage of the bulbs to ensure your dimmer is a match. You’ll want to choose a non-neutral wire dimmer if you don't have neutral wiring. Homes built before 1985 that don't have updated electrical systems may not have neutral wiring.

There are a few signs of a faulty or failing dimmer switch. This includes your dimmer overheating or feeling warm to the touch, buzzing or clicking noises coming from the dimmer, your dimmer failing to properly dim the lights, and flickering lights. That said, these signs could signal other electrical issues. You’ll need a pro to figure out if your dimmer is the source.

Yes, a faulty or broken light switch can be a serious fire hazard. Malfunctioning switches, often due to loose connections, exposed wiring, or overheating, can cause sparking or arcing. If you hear a crackling, popping, or hissing sound when you use the switch, it indicates live electricity arcing inside, which is a significant hazard that can ignite nearby flammable materials. If you suspect your light switch is faulty, turn off the power to that circuit at the breaker and contact a qualified electrician to remedy the issue.

First, check the current electrical code in your area to ensure spaces you’re considering meet the requirements. After that, your outlet’s location is up to you. If you’re moving it to hide wiring, you may want to move it in a spot that will also be hidden from view, such as behind a media center or table. As long as you meet the spacing guidelines set by electrical codes, you should be able to pick any spot in your home for an outlet. 

A pigtail is the only safe way to connect an electrical device to more than one circuit wire. Connecting multiple wires to a single screw terminal is extremely dangerous and must never be done. Many electricians will opt for pigtails even when there are multiple screw terminals available so that the device in question won’t halt the flow of downstream current when a problem arises.
