Default Re: Variac first or Isolation first ?

Interesting points you make there.
My isolation transformer hums anyway, and draws about 500ma with no load.
It's a potted hospital type.
So I definitely won't be runing it up to 265v !

And my variac is an older type with a floating case, photo below.
The entire case is metal and floating.

So you overall suggestion to house both is probably the safest way to go.

Thanks for that.
