I'm replacing a regular switch with the HS200. This switch switch is downstream from the GFCI outlet. The switch feeds an outdoor outlet.

The regular switch's Line is GFCI's Load. Swapping in the HS200 with that same setup blows the GFCI fuse. Wiring the HS200 directly into the Line so it's parallel to GFCI is probably above my paygrade but also blows the GFCI. I think that's because both GFCI Load and HS200 Load are wired to the Line of the downstream outlet. Not sure where to wire the GFCI load in this case but I'm sure what I did was wrong.

In short, a guide would be good, the HS200 actually came with no wiring guide at all.

thanks in advance
