Electrical FAQs, answered by experts

Be careful not to drop your voltmeter or multimeter. Even a small fall can affect the tool’s ability to measure with accuracy. Always store your tools in their cases in a cool, dark place. Also, avoid touching the probes to each other while they’re connected to a circuit or another electrical component, and never tamper with anything inside the device.

It’s recommended that you test GFCI outlets monthly with the test and reset buttons. At minimum, you should test GFCI outlets when entering a new season, or every three months. These are important home safety features that you should ensure work properly.

The average lifespan of a home electrical system is anywhere from 30 to 70 years or more, depending on the type of system you have. Modern electrical wiring, like aluminum or copper, can last 50 to 70 years while older types may need to be replaced sooner. Additionally, circuit breakers tend to last anywhere from 30 to 40 years, while electrical outlets need to be replaced every 10 to 25 years. 

The key difference between a circuit breaker versus a surge protector is that circuit breakers shield your entire electrical system from overcurrents and faults, while surge protectors defend your electronic devices against voltage surges and spikes. A circuit breaker interrupts the flow of electricity in a circuit when it detects an overload or short circuit, protecting the wiring from damage and preventing fires. In contrast, a surge protector shields electronic devices from voltage spikes, such as those caused by lightning strikes or power surges, preventing damage to the device’s inner mechanics.

Incandescent lights are glass bulbs with metallic filaments inside, while LEDs feature “light emitting diodes” that illuminate when they come in contact with an electrical current. You can buy either for your Christmas lights, but note that LED lights are more energy-efficient and have a longer lifespan.
