ECN Forum Forums General Topics of the Trade General Discussion Area Multiwire (Edison) circuits and GFCI

This reading was nothing to worry about, a digital VOM reads induction from the other circuit, try the same measurement with analog meter.

I run many multiwire branch circuits and as long as you follow the rules that apply to them they work great, how many service entrance neutrals do you have?

GFCIs do work down line from a multiwire branch circuit, not some times, every time.

Compare a GFCI fed from a multiwire branch circuit to a GFCI fed from a 2 wire branch circuit.

Once you get back to the panel it is the same thing, a common neutral.

One thing you can not do is protect outlets down line on a multiwire branch circuit with a GFCI outlet.

This is what electure and Electric Eagle where saying.
