Why Choose a Licensed Electrician?

All of your home's power is located in the service panel. The electrical service panel provides , , or more amps of power to a home. Homes built between and may have these ampere fuse boxes, often with four fuses. Power comes into the house from a service drop, connects to the service lugs within the service panel, and is split into separate circuits throughout the house.

By its nature, the main service panel is usually kept away from the main household activities. Likely locations:. While not typical, a service panel may be found on the outside part of an exterior wall, especially in the case of older fuse boxes.

One way to find your electrical service panel is to first go outside and locate the service drop and service head on your roof. The service panel should be directly below in one of the home's stories. For buried power lines, usually the line will start at the street and connect to the home near the front or side of the home. When the service panel's outer door is closed, the service panel is safe to touch under normal conditions. When the outer door is open and the circuit breakers switches are exposed, the panel is still safe to touch under normal conditions.

It is dangerous to work on an open electrical service panel with both the door and the protective front cover removed. Unlike the shock from a receptacle, which may or may not be fatal, a shock from the service lugs will most certainly be fatal or seriously hurt you.

In the service panel, two black heavy-gauge wires enter the panel from the meter base or a remote disconnect. The main entrance cable can enter the panel from the top, bottom, or even the sides.

These are the ends of the service wires that come into your house from the outside. Avoid touching these wires or anything that these wires touch. Connecting a breaker panel is very dangerous work if you are not an expert, and in most communities, the building codes may not even allow you to do this kind of major electrical work yourself. It requires coordination with the electrical utility company.

The electrician first makes sure the electricity to the feeder wires has been shut off by the power utility company. They will check the feeder wires with a voltage tester to ensure that this is the case. The electrician then opens metal knockouts for the main service conduit, as well as for each branch circuit that will enter the breaker box.

Yet another knockout may need to be opened for the main grounding wire. The knockouts are the round metal discs visible in the top, bottom, sides, and back of the box—of various sizes to match different-sized conduits that may need to connect to the box.

The electrician uses a chisel or old screwdriver to open the knockouts. They may do all of these at once, or start with only the knockout for the main service conduit, then open the knockouts for the branch circuits later, as individual circuit wires are run. Once the knockouts are removed, the electrician installs the conduit or cable connectors into the circuit breaker panel, securing them with the knurled locknuts threaded onto the tailpieces of the connectors from the inside of the panel.

Next, the electrician positions the circuit breaker panel, levels it, and anchors it to the wall with screws or anchors driven through the back of the panel and into the wall.

If the holes don't align with studs behind the panel, they may drill additional drill holes in the back of the panel to accommodate the installation or mount a piece of plywood to accommodate the panel. If the main service wires are entering the home through a conduit, the panel will be carefully positioned at this time so the conduit slides into the conduit fitting already mounted on the service panel. The electrician will now feed a fish tape through the main service conduit opening from inside the panel to the entry point outside the home where the main service wires are available.

There are normally three main service wires: two black hot wires and a white neutral wire. The main service wires are secured to the end of the fish tape with electrical tape and pulled back down into the breaker panel. It may require a helper to push the wires from outside while the fish tape is pulled from the inside, as these are large, stiff wires.

Plenty of excess wire is pulled into the panel to allow for connections to be made anywhere in the box. The main grounding wire—usually a fairly large bare copper wire—is fed into the panel and is connected to the main grounding connection. Usually, this is a metal lug on the back of the metal panel or at the end of the ground bus bar.
