OK, here are my reasons for PVC. I've installed, and repaired both, and had to completely repull the cables because a piece of "rigid" steel (that rusts right at ground level where the water gathers after a few years) was sharp as hell where it rusted and cut the cable. The ensuing fire/sparks/fault were extremely dangerous to the public, and guy who hit the pole. Just back into it? OK, if the angle is right MAYBE the rigid won't crush into the cable...MAYBE. Of course, it it is rusted, that ain't gonna happen, it's gonna crush and here we go through the fault routine again. Now lets repair. We have to have a major outage to replace rigid, in this area we use a pvc "cover" to enclose most of these conductors (and NOT on the street side, there were several design errors noted on this install that would not pass muster here) and it replaces quickly. The cover is sold by AB Chance if you guys wanna see it, and is extremely strong, you can also purchase metal. In case of a fault no one can detemine [Linked Image]in hole fault can go on for some time, the PVC will not conduct it into some innocent passerby. Anyway, not trying to convince you, just stating my reasons that steel does not get past my design criteria. Low voltage anyone ????
