Electrical questions, answered by experts

Although homeowners can turn off a breaker, it’s vital to follow safety precautions when doing so to prevent serious and potentially fatal injuries. For instance, you want to ensure there is no water on the floor when you touch the breaker and wear protective gear such as safety glasses. Anytime you deal with anything electrical, it’s always best to be as safe as possible.

Choosing between 12- or 14-gauge wire for your house depends on the electrical requirements of the circuit. A 12-gauge wire is thicker and can handle more power, making it better suited for devices such as kitchen appliances, air conditioning units, or electric heaters.

A 14-gauge wire is thinner and can handle less electrical current than a 12-gauge wire. It's ideal for circuits with lower power requirements, such as lighting or general-purpose outlets in bedrooms or living rooms.

Modern homes have a lot of devices and appliances running at once. That means there are many different wires and cables throughout the house. Service entrance conductors (also known as service entrance cables or service feed wires) connect the external weatherhead for the utility pole to the circuit breaker box. This is your home’s connection to your local power grid.

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.

Your breaker box houses the breakers that control the circuits in your home, shutting them off if they overload or experience similar problems. Your meter box houses your electrical meter that monitors the electricity flowing into your house and measures its use for your utility company.

In some cases, both components are in the same box, but they don’t have to be together. Many homes have them split, with the breaker box inside for easier access and the electric meter outside.
