Electrical Panel Installation

The electrical panel is housed inside a metal box, which is typically painted gray. Inside the box you will see rows of switches; these are called circuit breakers. Each circuit breaker manages the electrical flow to a segment of your house. There will also be one large switch, usually at the top of the panel; this is the main circuit breaker, and it controls power flow to the entire electric panel. If you take the cover off the electric panel, you will see several other important components, including two hot bus bars, a neutral bus bar, and a ground bus bar. It is very important to have a properly installed panel to insure proper electrical flow as well as to prevent house fires.

Repair or Replace Electrical Panel

Repairing or replacing an electrical panel can be essential for safety, efficiency, and compliance with local building codes. Here are some reasons why you might consider upgrading your electrical panel:

  • You hear crackling sounds from the electrical panel.
  • You see corrosion and rust on the circuit breakers.
  • The interior of the electrical panel feels warm.
  • Appliances are running at less than full power.
  • Your home has a 60-amp electrical service.
  • Your home has 100-amp electrical service, but it still can’t operate some appliances.
  • Your older home has a fuse block panel or split-bus panel, which do not have a main breaker.

Subpanel Installation

The main electrical panel in your home is the conduit through which all of your home’s electricity is distributed throughout the house. Every home has one. Some homes also have a subpanel (or multiple subpanels) installed to distribute electricity to a specific, often distant, area of the property.

Possible reasons for a subpanel:

  • Larger homes
    Splitting a large house into several smaller zones each served by its own subpanel can be a good way to manage a large home’s electrical needs.
  • Additions built onto houses
    Installing a subpanel for, say, your new master suite requires far less material and manpower than running circuits all the way back to the main electrical panel.
  • Garages and workshops
    It’s common to trip circuit breakers in areas where heavy equipment and power tools are used. Resetting a tripped circuit breaker in the garage’s subpanel is much easier than walking through the house to reset a breaker on the main panel.
