Hi folks, i have a question regarding the CE code and having a Type MC cable with conductors and circuits fed from two different electrical panels.

my scenario: one type MC cable, part of a manufactured wiring system, that has isolated ground circuits and general purpose power circuits contained within the same armor. the ig circuits come from panel A and the GP circuits from panel B. both are 120 volts. is this acceptable in the CE code. if not why and what rule does this violate?

Thanks

RULE 12-106 WILL NOT ALLOW THIS, HOWEVER RULE 3030 WILL ALLOW IT IN CERTAIN CONDITIONS. CEC 20TH.EDITION 2006

This is dependent on the Manufactured wiring system you are discussing many can do it through there consolitation boxes before the manufactured wiring starts, both systems are then coming out of the same enclosure with an immediate disconnect close by (usally a quick connect contect connector). Most manufactured wiring systems have this not only set to conform to the current code but also in their CSA or UL listing. If you run in to specific issues with doing this each manufacturer has someone available to help you out with sending information or talking to the inspector.

Without knowing more details it is hard to determine whether or not this is in violation of 12-106. As long as the circuits are not derived from different systems you MAY be ok.

I think rule 3030 from Yorky's post was a typo as Section 30
has to do with lighting.Most likely meant 12-3032?(Or 12-3030?)

I am still using the 19th edition of the CEC so there may be slight differences.
