525.32 Grounding Conductor Continuity Assurance

A new requirement was added to require testing of the equipment grounding conductor. This new section reads:

The continuity of the grounding conductor system used to reduce electrical shock hazards as required by 406.3(C) [Receptacles - Methods of Grounding], 250.114 [Equipment Grounding - Equipment connected by Cord and Plug], 250.138 [Methods of Equipment Grounding - Cord-and-plug-connected Equipment], and 527.4(D) [Temporary Wiring -Receptacles] must be verified each time the portable electrical equipment is connected. Figure 525-1

Intent: Testing of the equipment grounding conductor is required to ensure a greater level of electrical safety at carnivals, circuses, or fairs.

Author’s Comment: This requirement seems vague to me because it does not specify how the grounding conductor must be tested, what circuits are required to be tested, and who is required to do the testing.
