Re: GFI required for an EWC?
izak, no probably not, that said, starting in 2002 all commercial kitchen 15 & 20 amp 120 volt receptacles where required to have GFCI protection, there are no exceptions for refrigeration.

Is the compressor in the water cooler really any different?
Starting in the 2005 NEC all vending machine outlets must be GFCI protected again no exceptions for refrigerated vending machines.
I have read that the cause of these false trips in the past with refrigerators and freezers had to with the electric defrost heating elements contained in them not the compressors.
The electric elements had enough leakage current to trip the GFCI when the defrost cycle started.
A wall hung water cooler will not have defrost elements.
Most systems work best if they are kept simple rather than made complicated; therefore simplicity should be a key goal in design and unnecessary complexity should be avoided.
