GFCI Receptacle for 250V?
GFCI Receptacle for 250V?
(OP)
For UL508A purposes, we typically run any non-UL listed devices on our 120V systems through a GFCI receptacle. We have a project where we are using 230V and our standard GFCI receptacle is only rated for 125V. I'm guessing I need a 6-20R receptacle configuration with a GFCI, but cannot find one, does anyone have any suggestions?
Thanks.
Thanks.

The normal considerations are still the best - proximity to water or hard grounds.

Not a receptacle, also not a breaker.

i would definitely be interested in it for future projects, do you have a link for these at all? we were on a short time frame for this project, so we went with a GFCI breaker, but i'd like to get info on your solution for next time...

The UL procedure in question is twofold. You must protect the unevaluated (non-UL listed) device with a LISTED GFCI, AND it must be fed from a Class 2 isolation transformer. Class 2 means that the total power is limited to 100W or less. For something 230V, that is essentially 0.43A maximum. So keep that in mind because if your non-listed device needs more than 430mA of power, you are SOL.

I don't see the Class 2 requirement, just isolation -- and Class 2 can't be above 30 VRMS. Are you looking at appendix B, or am I missing something?
Holler!
