Electrical FAQs, answered by experts

It is possible to change a light fixture by only flipping the light switch, but it’s better to be safe than sorry. Exercising extra caution when working with electricity is always important. Take the extra few minutes at your electrical box to cut the power at the circuit breaker. Once you’ve flipped the circuit breaker and the light switch, use a voltage tester to confirm the power has been turned off.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

No, it’s extremely dangerous to cap off live electrical wires. Working with live wires puts you at serious risk of electric shock, which can cause injury or even be fatal. Whenever you need to cap off electrical wires or complete any electrical work in general, it’s essential to shut the power off at the breaker before you begin.

Often, you can add extra breakers to an electrical panel. A new breaker can help with new appliance needs, and it’s a common solution when finishing an attic or basement. However, adding extra breakers can’t bring in more amps to your house, so you still need enough amp service to power everything in total. 

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.
