Installing a new service for an old ice cream machine. Article 422.51 says I need a GFCI receptacle for this, but the owner of the machine is afraid of nuisance tripping melting all the ice cream. I have read that you should not feed freezers from GFCI's b/c the compressor will cause false trips. Anyone know if this is true, or if the newer GFCI's are better, or is there another way around it?

Thanks for the help.

Sure...what code year is the town using :) 2002 NEC does not even have a 422.51.

My 2005 is out in the truck...so I'll have to let others reply - or you will have to wait for me to return in about 7 hours :D
 
Re: GFCI Receptacle on vending machine

It's not the GFI fault, it is the appliances fault. The manufacture has to build the appliance with the leakage current at a level lower then the trip setting of the GFI.

Are we inside and in a kitchen or outside/mobile?
 
Re: GFCI Receptacle on vending machine

Is an ice cream machine a vending machine? If so there is no way around this requirement unless the vending machine has integral GFCI protection as part of the attachment plug or in the power supply cord. Old vending machines that are cord and plug connected must be used with a GFCI protected outlet. Someone might suggest hardwiring the unit, but then you'll hear all sorts of arguments about violating the units' listing.

Make the plug not accesible then it would not have to be gfi.

Please back that statement up with a code citation.

422.51 is pretty explicit in requiring GFCI protection for cord and plug connected vending machines.

What kind of an ice-cream machine is this? Will this set in a restraint for the public to serve their selves? If it is not going to be where the public has access then keep it out of a kitchen area and things will be okay.

422.51 has no exceptions...all vending machines must be GFCI protected.

It is a vending machine, and is inside...on a loading dock for public use.

My question really was whether I should expect nuisance tripping since it was a freezer and if there is anything I could do about it?

Vending machines have the words "vending machine" on their label. Some also have the words "refrigeration vending machine" on their labels.

Based on this I believe that this machine is a vendor or in other words a person drops in a dime and get an ice-cream sandwich, a vending machine.
If this is a true statement then this machine will be required to comply with 422.51 with out exception.

Cord-and-plug-connected vending machines not incorporating integral GFCI protection shall be connected to a GFCI protected outlet .

Take note that this would also apply to a hard wired machine as well.
