The NEC® requires 15 and 20-ampere, 125 volt, single phase receptacles supplying power for garage door openers located in attached or detached garages associated with dwelling units to have ground-fault circuit-interrupter (GFCI) protection for personnel.

As well, the device providing the GFCI protection must be readily accessible which usually results in a standard duplex receptacle installed on the ceiling, and supplied from the load side of a GFCI circuit breaker or from the load side of a GFCI type receptacle located elsewhere in the garage.

In North Dakota, the rules are a bit different. Refer to the Laws, Rules and Wiring Standards of North Dakota for additional information.
