Good morning all,
I am trying to determine if one can put in ground fault relays in place of ground fault breakers for commercial kitchen appliances.
Please respond with some feedback. Thank you
 
210.8 specifies "GFCI protection for personnel" which pretty much leaves the door open for any listed device.
With the new rules for GFCI on higher amperage circuits where there are no breakers available you would have to use alternate method from a breaker.

I stand to be corrected but one that does is Littlefuse SB500 which does provide Class A protection.

Yep. I did not say there where none, just they werent common. They are starting become available but usually as SPGFCI.

Not to be pendantic, but the company name is Littel not little.

AD, AccuAmp, offers sensors that are selectable from 5 to 30 milliamp range. Certainly does not mean they suitable for 210.8 protection.

When using external relays, do not forget to include the trip and clearing times of your power interruption device using the UL formula for Class A GFCI. It may not be a deal breaker but you never know, especially if you are employing shunt trip coils on breakers.
