We've got dozens of installs here, and more recently in Hawaii with Romex
coming out of the bottom of a soladeck into the attic space, just make sure the
Romex in the attic is labeled and it's sized correctly....

Glenn/Jason,
So you wouldn't use romex to feed an exterior outlet on an outside wall, or to
any outside lights???
Canadian Electrical Code's (CE Code) definitions…
wet location -a location in which liquids may drip, splash, or flow on or
against electrical equipment.
Damp location –an exterior or interior location that is normally or
periodically subject to condensation of moisture in, on, or, adjacent to
electrical equipment an includes partially protected locations under canopies,
parquees, roofed open porches, and similar locations.
Dry location –a location not normally subject to dampness, but that may include
a location subject to temporary dampness as in the case of a building under
construction, provided that ventilation is adequate to prevent an accumulation
of moisture.
If inside your attic is considered a "wet location", then you have other
issues. Are you sure the NEC's definition of 'wet location' is relating to the
location of the romex?
I just spoke to one of my inspectors and he sees no issue with entering the
bottom of a soladeck with romex.
On the grounding/bonding, I have been using the bare wire in the romex for the
enphase system ground (within the enphase cable) and running a #6 from the mod
frames and rails into the soladeck and along side the romex back to the
panelboard.
I need to get myself a copy of your NEC so I can be on the same page as you
guys. I hear it is written in a way that is much easier to interpret than the
CE Code, which is written in a very legal jargon.
Cheers,

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.

Subject: [RE-wrenches] Enphase and Romex
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).
