Turning Your Electricity On and Off

Main Switch

Main Switch
  • 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.

Fuses

Fuses
  • 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.

Circuit Breakers

Circuit Breakers
  • 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.
