Hello, I am new to the forum. I'm not a tech but a project mgr/estimator. I have been told that according to NEC code, a LV tech cannot install conduit more than 5'. If the conduit will be longer than 5' it must be installed by an electrician. The state of MN follows NEC, however, a state elec. inspector said he has never heard of this rule. Can anybody clarify? I spent some time online and couldn't find it. The next question would be, can we remove empty conduit? A customer is asking us. Thanks in advance.
Like was mentioned, this is local/state rules. The better question is "do you need an electrical permit for your work?". If not, and many states do no require electricians to install comm cable, then your LV guys can *probably* run ENT.
Keep in mind that most things dealing with LV, commercially anyway, are going to be governed by Life and Safety Code and Building Code (Chapters 7 and 8 of the NEC are pretty thin). If your guys do it, like we did back in the day, you need to make sure they do it right.
Most jobs we prefered the EC to run conduit, tho we did numerous hotels ourselves. If your guys dont know how to do it, have the EC do the conduit.
I would not remove empty conduit; I'm not a demo crew, and if it's metal conduit, it may still be serving as a ground path. Empty =/= not being used/abandoned.
