525.23 GFCI Protection

This section was extensively rewritten to clarify where GFCI protection is required, where GFCI protection is not required, and where GFCI protection is not permitted.

(A) Where GFCI Protection Is Required. Figure 525-1
(1) GFCI protection is required for all 15 and 20A, 125V nonlocking type receptacles used for disassembly and reassembly of amusement rides and attractions, or readily accessible to the general public.

(2) GFCI protection is required for all equipment that is readily accessible to the general public if it is supplied from a 15 or 20A, 125V branch circuit
.


Author’s Comment: Circuits are rated 120V and receptacles are rated 125V. I’m sure the 2005 Code will change the voltage rating of this circuit from 125V to 120V.

Ground-fault protection can be an integral part of the attachment plug or located in the power-supply cord, within 12 in. of the attachment plug. Listed cord sets incorporating ground-fault circuit-interrupter for personnel can be used to meet this requirement.

(B) GFCI Protection Not Required. GFCI protection is not required for receptacles of the locking type.

(C) GFCI Protection Not Permitted. GFCI protection is not permitted for egress lighting.

Author’s Comment: The purpose of not permitting egress lighting to be GFCI protected is to ensure that exit lighting is maintained.

  • What exactly does the locking of a receptacle have to do with gfci protection? Its not as though the general public can not unlock it. What if the cord became damaged an is laying in a puddle of water, what protection would the twist lock offer Mike

  • Article 525. If a single, 120 volt, 20 amp receptacle is of the locking type does that mean it is not required to be GFCI protected? It appears straight forward but I just wanted to make sure.

  • I am unclear as to why the method for insertion and extraction for plugs and receptacles (locking or non-locking) would dictate the utilization of a GFCI, assuming the terms locking and non-locking refer to straight blade and twist-lock devices, and not the ability to apply a lock to the connected devices.

    Also, there is the issue of switch rating for GFCI's applied to inductive, or motor circuits.

    Thanks,

  • Mike -

    I can save the cost of a GFI, by switching to twist-lock in place of straight blade recepatacle and cord cap on 15 & 20 Amp 120 volt circuits? Is this correct? and Twist-locks protect me from groundfaults? I must be missing something.
