I am getting started on wiring a truck stop. The maintenance guy/electrician for the petroleum supplier tells me that he uses aluminum conduit underground...coated with a two-part epoxy to resist corrosion. (he uses it because it is easier to bend.)
Is this a valid way to use aluminum?
One report that I read (1999) said that aluminum cannot be used unless it has additional corrosion protection. It went on to say that no coating has been investigated (by UL, I guess) that provides this protection, so the use of aluminum underground is not allowed.
Is this still true? (Believe me, I do not want to run aluminum conduit underground)
Thanks!
