D 3 number 12 wires equal one number 8 wire?
Do three #12 wires equal at least one #8 wire?
In a sub panel I see 2 #8 wires in a 2 pole Circuit breaker and 3 number 12 wires are joined together and go from the neutral bus in the sub panel to the (one) neutral/ground bus in the main panel.
the 2 #8 wires are getting their juice from a 2 pole (40 amps per pole) Circuit breaker in the main panel. (back feeding)
My question: will the three #12 wires carry the neutral load safely?
This is not code at all.
Unless this is in conduit, the following are the reasons.
All your conductors need to be bundled together (as in romex or UF cable)
And your Neutral is not allowed to be undersized.
Get us a picture if you can because this sounds like someone messed it up bad.
Also, if you have a subpanel you also should have a Ground Bar that is wired to the main's neutral/ground.
3 no.12's don't equal a #8.they need to be the same size as in 3 #8's.you can't do it.you need to change what you have.by code you need two hot's one neutral and one ground.
Only if you are wiring Speakers, not if working with Electric.
