Electrical questions, answered by experts

You should never unplug or touch a buzzing outlet. If there are appliances plugged in that are causing the buzzing, wait until the appliance is turned off (or turn it off yourself) and then unplug it from the outlet. Test the outlet by plugging in something that won’t use much power—a small lamp works well. If the outlet still buzzes, have a pro investigate why.

Most mechanical and digital timers will only turn your Christmas lights on and off once per day, but a smart timer will likely do so as many times as you want.

Just like apples in a bunch, one bad outlet can cause other outlets to stop working. This is especially true if the outlets are connected in a series on the same circuit. When one outlet develops a fault, it can spread to every outlet downstream of the original.

Yes, tamper-resistant outlets are designed to be safely used in your home. They have a spring-loaded shutter, which pops closed to internally block the slots when the outlet is not in use, protecting your child from the dangerous electrical current should they insert toys or other objects into one of the slots.

Yes, a water leak poses a major fire risk at your home because water is a conductor of electricity. Water that comes into contact with sparks or electrical wires can instantly ignite flammable materials. Additionally, any type of exposure to water can cause wires and other electrical components within your home to corrode. When assessing categories of water damage, it's important to know that even a small amount of moisture near wiring could cause sparks that lead to a fire.
