Welcome back Ian!
I got around that USA up/down debate by mounting the pair of NEMA 5-15s sideways
Nevermind. We can still debate whether the "hot" side of the receptacle should be up or down!
Speaking of which, did you move the earth to one end of the secondary on the site xfmr, or did you leave it on the center tap so that both sides are at 55-60 volts?
