Looks like a cowboy with bowed legs who just got off a horse
Call it what you will. All I know is when I ask for a 2 inch cowboy at the supply counter they know what I’m talking about. That’s all that counts for me.
Reminds me of a joke.
Your that guy that makes all the young counter help go running for reinforcement,,,,
Agreed, but every once in a while you'll get an EI that makes you use them
Here they don't really care what you use for the house riser (overhead service riser) but underground emergence as well as entire run up side of a pole they typically want Sch 80. You don't have to actually run it up the pole but must provide it for them so they can run it up when they come to connect it.
Even an EMT fitting is not listed to install in said hub, yet there are a lot of those around as well.
Isn't exactly a code issue it is a listing issue. Only code an inspector can cite is 110.3(B), then has to support it with listing information on whatever is involved. Same with the hubs and not using RMC/IMC in them.I once had 2-hole PVC straps on a 2" PVC riser for a 200A service. It was in direct sunlight and after 1 year most of the straps snapped off. Fortunately, the one at the top near the weather-head didn't. I went back and replaced them with 2-hole metal straps. I know it's not Code compliant but the CMP's making these rules are not out here in the field installing these services (maybe they did at one time and forgot what it's like). I don't know if they realize that we're not installing T-stat wire inside these conduits.
Had one once that was *expletive deleted* enough and would reject the metallic straps, yet would let us pass inspection if we had both metallic straps and PVC straps on the conduit, because he knew those PVC straps probably won't hold up in the environment
The meter socket enclosure is governed by Article 312, and 312.2 says "For enclosures in wet locations, raceways or cables entering
The closest thing I can find is that 352.30 says "PVC conduit shall be . . . fastened so that movement from thermal expansion or contraction is permitted." Do metal and plastic 2 hole straps differ in that regard?
