Electrical questions, answered by experts

Yes, blue wires can be hot wires in the U.S. However, they are less common in residential properties than red and black hot wires. Blue wires are typically used as traveler wires in three-way and four-way switches, as well as ceiling fans. They allow fixtures to be controlled by multiple switches, like when there are switches at the top and bottom of a staircase for the same light.

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.

Yes, the National Electrical Code reviews household codes every three years. However, that doesn’t always mean that kitchen counter outlet requirements will change, but it does allow room for professionals to make updates. That’s why many older kitchens are no longer code-compliant thanks to changing rules for amperage, GFCI protection, and more.

When power is restored to your home, the transfer switch will return to utility power after about 10 seconds. Your generator will then run for a few more minutes to cool down before automatically shutting itself off. In most situations, your home will stay powered by the generator for at least five minutes, even after your power comes back on.

To check if doorbell wires are live, use a non-contact voltage tester. Hold the tester near the wires; if it lights up or beeps, the wires are live. Always ensure the power is off at the breaker box before handling any wiring. If you don't have a voltage tester, consider getting one or consulting a professional to ensure safety.
