Anyone know where to look for reasonably priced (probably fiberglass) underground hand hole / pull box / vault?
I see lots of information about them from many manufacturers but, of course, they are all oriented to volume purchases and large commercial distributors. I'd rather not have to go through a quoting exercise with multiple places.
Have two uses for them along a long driveway, 120V power and low voltage. Also, if anyone knows, what are the restrictions about putting both in the same vault?
I've been told by my electrician that I shouldn't have any problem with a common trench for 120V and low voltage. He recommends conduit for the 120V at least (and I'm thinking a mix of direct-burial cable and empty conduit [for future] for low voltage). Claims there aren't any spacing requirements (not so sure about that). Electrical code says power must be 18"+ deep. (Will cross under the driveway in some places.)
