Conduit

Posted by ROANIN on July 21, 2009, 9:07 pm

Can one of you code book guys tell me if it is required by code to put
single wires in conduit? I am putting a sub panel in a building and want to
know if it is required to put the three #2 wires which will be feeding it in
conduit from the originating circuit breaker panel, across the top of the
building to where it enters the underground conduit to the next building?

Thanks,

Roanin

*Single conductors that are not in a cable must be in conduit. Going over a
roof requires that you make allowances for temperature as well as expansion
and contraction of the conduit. A grounding conductor may also be needed.
