[RE-wrenches] Strawbale wall penetration

[Glenn Burt]

Would the walls of the bale house be considered part of the dwelling and
require careful consideration of whether metallic conduit is REQUIRED on the
DC run? 690.31 (E)

Wrenches, 

Short of contacting the builder, i'm looking for your experiences, practices
and "look-out's" for penetrating a strawbale exterior wall with conduit.

 

For the project in question there is currently a teck cable from a wind gen
entering the home by sharing a HRV vent opening that i want to fix (not my
original system by the way) and i will also be adding another penetration
for a PV array that i am relocating on the property. The original
penetration for the PV was done properly but its not in an ideal location
for the re-located array wiring.

 

I'm wondering if it is as simple as using a hole saw extension to go thru
the ~16" wall and use an LB/box on either side.  I'm sure there is some
framework and/or rebar supporting the bales, how do you locate/avoid these
when there are no corners to measure from?  (it is a round home)  

Any knowledge if PVC or EMT will react in anyway with the bales?  I'm
thinking that PVC would be best....?

 

... i am trying to contact the builder to address this, and also to ask a
few choice questions regarding the wiring methods (he?) used in the original
PV system set-up.

 

Cheers,
