Turning Your Electricity On and Off - Know where your main
electrical panel is, so you can turn off the electric supply to
your entire facility quickly in case of an emergency. - Know
where your fuse box or circuit-breaker box is located. - Know
the correct sizes of any fuses needed and keep spares on hand.
Blown fuses must be replaced, not repaired. Do not replace a
fuse with one of higher amperage. - If a fuse blows, disconnect
or turn off the equipment that may have caused the problem. -
Shut off the main electric switch before replacing a fuse. -
Know how to reset a circuit breaker. After turning off or
unplugging equipment on the circuit, push the switch firmly to
the off position, then back on. If the overload is cleared, the
electricity will come back on. - If your circuit breakers trip
off repeatedly, there could be a problem with the equipment on
that circuit. If the equipment is unplugged but the circuit
breaker trips off again, call an electrician.
