Don, that's where the NEC has me puzzled. It starts off by saying IF raceway materials are used as the mast ....
As shown in my first pic, there are plenty of way to have a mast- without using a raceway at all.
Otherwise, the language seems to suggest that there just might be other ways to make a mast, apart from using electrical conduit. Are they suggesting this? Or, are they referring to perhaps using, say, EMT for the wire - and something else to take the loading? I simply don't know. It seems that if the code panel wanted to require you to make the mast in a particular manner, with particular materials, they certainly could have said so.
