Dspark,
Will this GFCI detect a balanced leakage, e.g., a 1.0000 ampere leakage on T1 and 1.0000 ampere on T2?
That's a good question.
My first reaction would be to say no. But when thinking of it as a complete circuit (going back to source) I'm confused. You're right, a good Theory topic.
I just noticed the Labelling seems to be wrong on the diagram. the Neutral goes thru the contactor and becomes T1 ??
Do you see that the same way or is it my tired eyes (I didn't draw it) If you agree it's wrong I'll correct it somehow.
