pole mounting and conduit questions [RE-wrenches]

[Jeff Irish]

Talk to your AHJ.  Ours let us slip the base plate and column over an 8 inch
high PVC stub out in the concrete base and run THWN-2 wire up the inside of
the column.  Technically a 6 inch diameter steel pipe with 1/4 inch thick
walls is not a UL listed conduit but our AHJs believe adding an interior PVC
conduit would be silly and that the steel pipe provides more than adequate
protection.  One however, requires us to run bare #6 down the outside of the
column.

Subject: pole mounting and conduit questions [RE-wrenches]

Does anyone have experience running conduit up through a pole? How do
you enter the pipe at the bottom? And do you run conduit all the way
up the pole or does the pole itself become your conduit?

We're using anchor bolts with a pre-welded plate on the bottom of the
steel pipe. See photo here:

What I'd like to do is run conduit up the inside of the pole and exit
through the "gimble" on the poletop. See an example of a light post
here: http://www.flickr.com/photos/14918878@N04/2214578212/
I haven't seen this done with PV but I'm sure it's possible. The DP&W
racks come with a knockout on the gimble, for this purpose. Not sure
about Zomeworks, though.

Any feedback is appreciated.

Thanks,
-Nik
