[RE-wrenches] Enphase and Romex

[Glenn Burt]

Soladeck on the rooftop places it in an environment that is considered
'wet'.

I don't think Romex is listed for use in a wet environment.

 

This would force you to use the proposed jbox in the attic for the
transition location.

I also understood that you could combine the EGC and GEC into a single
conductor as long as it is continuous or irreversibly spliced, as part of
the '08 code.

I'm sure this has been covered, but I could not find it in the archives.

 

We are considering using Romex in the attic for the first time. My plan was
to use the new Enphase coupler to connect the trunk cable to Type TC-ER,
enter a Soladeck passthrough box on the roof into a junction box in the
attic where I would make the transition to 10/3 Romex. I'm hung up on the
GEC going back to the service panel. Any suggestions?

 

By the way, we are on NEC 2008, and in most cases there is also a
requirement for an additional grounding electrode per NEC 690.47(D) (that
shouldn't really relate to my issue).
