Electrical Panels 101

Let's take some of the mystery out of those wires and switches that lurk behind the door of your breaker box. Come forth and have a peek with u.s.a., but don't affect!

In your home—in everyone'southward homes, in fact—the seat of electrical ability takes an unassuming form. Curtained by a nondescript metallic door, the breaker box doesn't expect very impressive, but information technology's the reason you can turn on the lights, the blender, the air workout, and the Tv set. The breaker box, or service console, operates as a primal relay betoken: It takes power from the street, and then feeds that ability to the different electrical outlets and hard-wired appliances throughout your residence.

Nearly people open up the breaker box only when in that location's a trouble—for instance, when a circuit needs to be restored after tripping. And that'south the way it should be. Homeowners are wise to exist hands-off with electrical elements, especially those they don't empathize. Make no mistake: The billow box is dangerous.Hire a licensed electrician if you think the panel needs attending. The goal of this commodity is merely to explain a fleck more almost all of those mysterious wires and switches.

Double Pole Service Disconnect

At the meridian of the breaker box, the switch that'southward bigger than the others is commonly referred to as the "primary." (Technically, it'due south called the double pole service disconnect.) This is where, later passing through your electricity meter, two hot wires from the utility visitor hook up to your business firm. Each wire carries 120 volts. If y'all were to put this switch into the off position, the electric current to your house would exist broken and your dishwasher would suddenly stop running. Plough the switch back the other manner, and your dishwasher—non to mention your refrigerator, home role computer, and sleeping accommodation alarm clocks—would come back to life.

Hot Motorbus Bars

From the primary breaker, each one of the ii hot lines from the utility company passes into its own passenger vehicle. To the heart, a autobus looks similar a regular metal bar. One bus runs vertically along the left side of the console. The second motorcoach runs vertically forth the correct side.

Neutral Bus

A third metal bar, the neutral motorbus, receives the electrical electric current back again after information technology has exited the breaker box and flowed throughout your home doing its work.

Circuit Breakers

The circuit breakers straddle the hot motorbus confined, and if at that place's an overload—say, from likewise many appliances running simultaneously—the affected circuit trips and automatically suspends the electrical current. In improver, excursion breakers serve every bit the origin points for the wiring that runs to different parts of your habitation. That'due south why there are labels (with the names of rooms or major appliances) next to the individual switches. Each circuit has two hot wires feeding into the billow, as well as a neutral wire that connects to the neutral bus. Together, these three wires exit the breaker box and get on to provide the juice for their designated circuit.

There are two chief types of breakers:

• Unmarried Pole: These consist of i switch, handle 120 volts, and can be either 15 or twenty amps.
• Double Pole: Handling 240 volts with amperage ratings from 15 to 70, these await like ii switches joined together.

Hardwired lighting, electric outlets, and baseboard heaters typically require 15- or twenty-amp breakers. H2o heaters and dryers are best served with 30 amps. Meanwhile, electrical ranges have 40- to l-amp breakers, and such things equally the air conditioning system may exist served by an even larger billow or a subpanel.

The wiring into a billow must correspond to its amperage. Twelve-gauge wire suits xv- to 20-amp breakers; 8-gauge wire goes with 40- or 60-amp two-pole breakers.

Grounding

In the maze of wires that inhabits your breaker box, there'southward one more than to be aware of: the grounding wire. Typically a blank copper wire, information technology connects the neutral bus to a metal water piping (or to a metal rod buried in the earth). Grounding prevents currents traveling through frayed wires from carrying on to metal surfaces they weren't intended to reach.
