Circuit Breakers

Overloads can cause fires. Circuit breakers protect the wiring system from an overload. They do not protect people.

Ground-Fault Circuit Interrupter (GFCI)

A GFCI is specifically for people safety. A GFCI can be hard-wired into an electrical box. A portable GFCI can also be plugged into any electrical outlet. If there is an electrical short, the GFCI prevents an electrocution.

Review These Important Points

  • Electricity always follows one or more paths of least resistance.

  • Use an effective ground.

  • Only electricians should make electrical installations or repairs.
