GFI recep with GFI cords? Unmixy?

[GoldDigger]

So, in some locations, this double GFCI is actually mandatory; so they had better be compatible.

Does the "pop machine" trip the GFCI as soon as you plug it in, or does it work ok for a while and then trip it?

Runs for a while. Not a set time or anything.

When you say "shop" is a GFI required? If you ran the wire can you just put a single receptacle and be done with it.

I did this and expect no problems. But by code it should be a Gfci

Well, interesting enough that it runs for while then trips GFCI. You may have a faulty run capacitor on the compressor or some other internal problem that is getting by the cord mounted gfi ( by the way does anybody know if cord mounted gfi's are 30ma or 5ma fault protection).

They are supposed to be 5-6ma just like any receptacle, or GFCI breaker in that class.

It would depend on what level of protection they are intended to provide. Since this is supposed to be a vending machine and NEC now requires a GFCI in the supply cord of newer or newly rebuilt machines it is probably the class A 4-6 mA variety.

I do have suspicions as to whether or not it does provide proper protection though given some of the information we have - unless the wall receptacle GFCI is miswired or something.

That run capacitor should be in the circuit anytime the compressor is running and would likely trip anytime compressor is supposed to be running if the problem is the capacitor, and not just at random times.

What I have seen trip GFCI's more often with refrigerators or freezers is failed defrost heaters, foreign material that is conductive enough getting into exposed terminals of either capacitors, compressor terminals, thermostatic controls, etc. or just the general failure of such components developing some minor fault to ground that doesn't otherwise leak enough current to trip the branch circuit device should there not be any GFCI protection.
