Electrical questions, answered by experts

The copper wire used in knob and tube wiring systems can last up to 100 years. However, it’s considered a dangerous and outdated wiring method because the cloth, fabric, or rubber insulation sheathing can become brittle and fall apart. Knob and tube wiring systems should be inspected if you’re considering buying a home with this type of wiring, or if you have problems with frequently tripping breakers, a sign that you may need to replace them.

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.

Some warning signs that your electrical meter box is overloaded include frequent circuit tripping, scorch or burn marks, and flickering lights. You may also notice a burning scent coming from the electrical panel. Keep in mind that a circuit breaker trips as a protection measure; it turns itself off to prevent potential fires.

The purpose of pigtail wiring is to connect multiple wires to a single terminal on a device. Pigtailing involves splicing a short length of wire, called a pigtail, into the multiple wires that need to be connected. The pigtail wire is then connected to the single terminal on the device, allowing all of the wires to be connected at once. This practice helps to simplify the wiring process, reduce clutter, and ensure a secure and reliable electrical connection.

If all of the outlets in one room suddenly stop working, it’s likely the result of a tripped circuit breaker. This easy-to-resolve malfunction is caused by overloading the circuit with too many working appliances at the same time. Locate the tripped breaker in your electrical panel and reset it to restore power.
