UL 508A Frequently Asked Questions

Q. UL Table SB4.1 declares GFI receptacles as 2K rated. If used in a single phase control panel (no stepdown transformer) does the SCCR follow the GFI protective device rating of the 2K rating of the GFI receptacle?

A. Yes if the GFCI receptacle is the lowest SCCR rated component in the power circuit. Otherwise the panel SCCR would be that of the lowest rated power component.
