Flush-mount exterior electrical boxes in board & batten with rigid foam and rainscreen?
Good evening all,
I’m still working thru issues involving board and batten over strapping and rigid foam. Now I’m looking into the exterior electrical boxes (for outlets and for lights).
I’d like the boxes to be flush-mounted, with the “rain screen” (do we still call it a rain screen if the strapping is horizontal?) space serving as a conduit chase. That would minimize penetrations of the insulation and WRB- while avoiding surface-mounted conduit.
Important note: I’m in the Chicago area. Here, all electrical boxes have to be steel, and all wire has to be inside EMT or conduit. No flexible metallic cable or Romex allowed.
Initially, I had planned on 5/4 board for strapping, but now I realize that won’t leave much depth for electrical boxes- so I’m considering 2x strapping instead.
At this point, I’m looking at ordinary steel boxes and mud rings, with an as-yet-unidentified weather-tight gasketed “cover” on the outside.
1) Is there a better approach? 2) Does this “as-yet-unidentified weather-tight gasketed cover” actually exist? -or is it only in my imagination? 🙂
Thank you so much for your help.
