Okay I work in a laboratory enviroment where i have to install two new receptacles in a room. Is it legal to run flex down the wall or do i have to run EMT? Maybe about forty feet long? Please help
Always run a grounded conductor. Just having a discussion with my leadman and he thinks we should run EMT in walls. Without ripping away walls Flex should be legal to run. He swears that in our enviroment flex shouldnt be used. I cant find anything that says we cant.
EMT (Thinwall) is allowed to be fished without couplings.
