Where does the current come from for a disconnect switch?
This describes the basic wiring setup for a separate disconnect breaker switch. Disconnects receive 240 volts and lethal current from feeder lines coming from the utility meter. The feeders and the terminals they connect to on the disconnect switch are live at all times unless the utility has shut off the power to your service.
