roger said:This is the very reason our respected late friend Bennie Palmer would say it's safer not to ground or bond anything in a raised wooden structure.
Which is one reason I feel that GFCI protecting an old 2-wire circuit if you want 3-wire receptacles is safer than rewiring that circuit. The GFCI will trip at 5 or 6 ma. The grounded circuit will permit a fault to exist up to the ratign of the OCPD.iwire said:By bringing the EGC into the room we have brought half the circuit needed to kill someone.

jerm said:have you ever tried this?! It's nearly impossible, I tried tig, mig, and stick. they all blow holes in it even at low settings, until you're so low it won't stick. I'm sure a real welder could figure something out, but I couldn't weld it at all!!!
If it was, it could be done. Commercial ductwork guys can MIG 30 gauge sheet metal. I took a night school welding class where the instructor TIG'd back together a Mountain Dew can.Jim W in Tampa said:I was joking it would not be legal
