ECN Forum Forums Code Related Discussion NEC & other Code issues separate branch circuit for elevator pit lighting and receptacles

NEC 620.24(A) says that "A separate branch circuit shall supply the hoistway pit lighting and receptacles. Required lighting shall not be connected to the load side of a ground-fault circuit interrupter."

In our office, three electrical engineers have the each differenct interpretations.
Those are following.

A)Elevator pit lighting circuit is independent. so don't connect to any other lightings installed at near space out of pit. Elevator pit receptacles circuit is likewise. In addition to that, don't connect also between pit lighting and receptacle.

B)Elevator pit lighting doesn't need dedicated circuit. It can be connected to any other lightings at near space out of pit. However it shall not be connected to receptacles in elevator pit. Receptacles in pit are likewise.

C)Elevator pit lighting and receptacles are included in one circuit. No other lighting and receptacles of outside of pit excluded for that pit circuit.

What do you think which one is right?
I'll expect your considerable insight. Would you enlighten me on this question? Thank you all for your sincere opinion in ahead.

I vote C.

"A separate branch circuit shall supply the hoistway pit lighting and receptacles."

That means one circuit for both.

"Required lighting shall not be connected to the load side of a ground-fault circuit interrupter."

That means line-side connection is okay.

C also. Just be sure that the light is on the line side of the GFCI receptacle that's in the pit.
If you've got a cord connected sump pump in the pit, do the same thing. The separate circuit that 620.24(A) calls for if for the pit light and the pit "convenience" GFCI receptacle.

In Maryland the State Elevator Inspector requires that Nothing else be on the circuit with the pit light and pit receptacle
Pit receptacle must be GFI and the Light Must NOT be on the load side of gfi. They will allow you to have them on seperate circuits,but nothing else can be on those circuits. We just run 1 circuit for both.
Also the Machine room receptacle must be GFI and on its own circuit. They are very strict with the Elevator shaft and machine room here.

To pass the elevator inspector's test the answer is A....

Nothing else will fly.
