Does a single receptacle for a sump pump located in an elevator pit need gfci protection? The drawings I have state that the receptacle should be “NON-GFI”
 
422.5(A)(6) lists sump pump outlets as being required to have GFCI protection. Since the GFCI protection needs to be readily accessible it probably should not be within the pit.

What code cycle is that from? The 2020 added this:
620.6 Ground-Fault Circuit-Interrupter Protection for Personnel.
Each 125-volt, single-phase, 15- and 20-ampere receptacle installed in pits, in hoistways, on the cars of elevators and dumbwaiters associated with wind turbine tower elevators, on the platforms or in the runways
and machinery spaces of platform lifts and stairway chairlifts, and in escalator and moving walk wellways shall be of the ground-fault circuit-interrupter type. All 125-volt, single-phase, 15- and 20-ampere receptacles installed in machine rooms, control spaces, machinery spaces, and control rooms shall have ground-fault circuit-interrupter protection for personnel.
A permanently installed sump pump shall be permanently wired or shall be supplied by a single receptacle that is ground-fault circuit-interrupter protected.

It's funny, 620.6 was removed after the 2011 cycle, it was moved to 620.85 that had the same wording Bussman posted which remained untill 2020 and then it was put back in with the new wording.
 
For the longest time, the sump receptacle was required to be a non-GFCI simplex.

Now the NEC requires GFCI, but I'm not sure if the elevator code (or whatever the inspectors enforce) matches that.

Good luck trying to predict which the inspector will require - in my experience, it's usually one thing for one elevator, and then something different for the next one.

If the shaft is sprinklered, the receptacle usually needs to be 48" above the bottom of the pit, or it has to be waterproof.
 
So from the 2020 NEC forward if it is not hard wired it must be a single receptacle with GFCI protection provided most likely with a circuit breaker.

The "sump pump" receptacle is handled separately and is not required to be a "GFCI Receptacle" as the others are. If it were intended to be the same, the section would be worded "A permanently installed sump pump shall be permanently wired or shall be supplied by a single receptacle of the ground-fault circuit-interrupter type."

I disagree with the interpretation in that article. It clearly requires either a single receptacle or hard wired pump. In either case GFCI protection is required. As Roger noted if the GFCI protection is required in the pit then the wording in 620.6 needs to be changed.
