Can someone tell me if a GFCI is required for a portable water cooler? The OSHA standard 1910.305(j)(2)(IV) is vague and states a receptable installed in a wet or damp location shall be suitable for the location. the compliance officer will usually reference a NEC code (i believe 210) to back their citation. is there a NEC code pertaining to GFCI for water coolers? why wouldnt a GFCI be required for a water cooler?
