while not on topic, this incident has made me take a close look at both my subpanels, and both are a mess. ground and neutrals mixed, one enclosure not even grounded.. fun things to fix!
only thing I don't understand, sub panel using plastic conduit,
master has ground/neutral bonded. sub not bonded.
if the conduit had been metal, the sub panel would have inherited the bonding.
what can/am I supposed to do about this?
bond at the sub (no/no)
leave unbonded (maybe?)
Bonding refers to the ground(green/bare and neutral/white) being tied together in the panel such as a jumper from the neutral bar to the panel metal or a wire from the neutral bar to the green bar. Metal conduit does not do this, it will only act as a equipment ground(green/bare) and no ties to the neutral. In your sub panels the green/bares and neutral/whites need to be on separate bars. Hope this helps.
helps, and thanks RCMAN.. (even in the text of this topic, the question/answers are conflicting. There is an 'assumption' by some, that a 'welder circuit' has a neutral. which it normally doesn't).
I have never seen a 220 circuit with a neutral except a dryer, which wants 110 for the electronics.
my subpanels will have them separated (one does, one doesn't as I type this, will be fixed later today).
