An electrical subpanel is a secondary circuit breaker panel that feeds off the main panel. It is installed for one of two reasons: either the main circuit breaker panel is already full of breakers and provides no room for installing additional circuits; or the subpanel is installed to put the control point for some circuits in a place close to the area they serve—such as in a woodworking shop or an upstairs apartment. When the goal is simply to add space for more circuits, the subpanel is often placed adjacent to the main panel.

Typically, while wiring a subpanel, an electrician will first extend a feeder wire from the main panel to the subpanel. The feeder breaker is then installed in the open double slot of the main service panel by the electrician. There are certain ways of Amp Panel wiring which are explained below.
