ECN Forum Forums General Topics of the Trade General Discussion Area Trough sizing...

... No, my helper got a little "ambitious" and went ahead and started the 1-1/2" run without me..he forgot the expansion coupling..he had it all glued together by the time I got to the site,I called the AHJ,and told him about it,and that it's only for Cable TV,and Telephone,and he said he wouldn't knock it down so long as the coupling was there for the 3" pipe.. I personally installed the one on the 3" pipe..I'm still stewing over redo-ing the 1-1/2" LB,anyway, and adding the expansion coupling there as well..I probably will,as there's no wire in the pipe ...yet..

Russ, brought up a good issue here, he may have solved his problem, but i see many under sized raceways out there, as Bob said, "The company I work for is more concerned with progress and passing inspection than worrying about the cost difference between an 18" x 18" can or a 24" x 24" can so I tend to figure big most times."

Working with larger conductors in a small raceway can be tough, but i still see many undersized raceways out there, i can't see the savings, when what you save on the box costs you 4 times over in labor.
