Doug, being a good Canadian these days, rather than a good Californian, I don't have a copy of the National Electrical Code. However, in it is a section 60 (or 600 ?) that says that Public Utilities are exempted.
I believe that most Telcos are state-regulated, not federally regulated, hence state-law covers them, not federal law. Most state laws refer to the National Electrical Code. I am not an attorney at law, but that is what attorneys have explained to me. Ciao, Vic
