Article 230.6 ??

[globe trekker]

Greetings to all!

I have a project where the electrical contractor wants to install service conductors

from a pad mounted transformer to a metal trough; which is on the exterior of

the building. From that existing trough, they want to install 4" rigid metal conduit

( RMC ) up in to a 400 amp. disconnect and then continue on up in to the "above

the ceilng" space of an existing, adjacent tenant space and run horizontally in to

the adjacent tenant space; through the tenant space separating wall

(non-fire rated) down into the new interior electrical panel.

I am questioning the proposed installation, citing Article 230.6 from the 2008 NEC.

QUESTION # 1: Can the EC install the conductors in this manner?

FWIW, after reading some more in the 2008 NEC, these conductors would be

considered feeders.

Thanks for any input!

Sounds like it might be OK......they have a disconnect upon entrance which should also be the service OCPD...and then the downstream panel would be a "sub" and G&N get seperated and so on.....
