I have to run a circuit to supply power to a sign across about 50 feet of flat roof. In the past I've put down 1 foot long pieces of treated 2X4 every 5 feet and ran PVC conduit. But this time I would like to do a neater job. I cannot run it on the side of a parapet. Can I run it on top?Or perhaps I should run EMT with compression fittings.
Any ideas out there?
Thanks
Bob
