An electrical sub panel is a smaller version of the main panel. It is a way to move many circuits to a point further away from the main panel instead of taking many single circuits from the main panel board. The sub panel has just one supply feed from the main panel. By using a sub panel there is a cost savings in labour and materials. On larger buildings there may be multiple number of sub panels. The amperage rating of the sub panel board governs the size of the wires and the breaker used in the main panel to feed it.
