Obviously referring to the main power switch on the Variac.....now as to load, I dunno, not messed with that configuration.....I would be more tempted to put the GFCI on the output....but that depends on your use, and why you need either one.....

One issue is these often run 24 hours/day with no one around, so tripping a GFCI will result in lost production if no one is around. If it only happens when turned on or off, that can be managed but if it trips the GFCI at random times, that’s a no go
