Coomercial Kitchen GFCI Recptacles

[Riograndeelectric]

commercial kitchens GFCI Oultets. Article 210.8.B lists that all 125V single pahse 15/20 amp recps in Commercial and Institutional shall have GFCI protection.

I had a call where the GFCI oultets had been tripping and it was not due to any ground faults but rather the heating elements creating havic on the GFCI.
Has any on thought about using a 30ma GFP Breaker instead of the normal 5ma GFCI.

That is a ground fault, have them replace the heating elements.

You can not use a GFP breaker for personal protection.

I agree with Bob. GFPE is for the protection of the equipment not people.

You absolutely need a megger to troubleshoot these nuisance GFCI tripping service calls. There's nothing fundamental about a heating element that will trip a GFCI. A failing (faulted or faulting) heating element will trip them. A megger will prove that out in short order. I find a megger to be an essential tool when troubleshooting intermittant GFCI and AFCI tripping issues.

Great unintentional pun!

We have heating elements in some of our machines that will occasionally blow fuses. You check the heaters and everything is fine, 2 days later same fuse blows again. Come to find out when they are heating/hot they can occasionally move and short out to ground.
