ECN Forum Forums General Topics of the Trade General Discussion Area Fixture whips

I looked at a job that had all of the chain hung flourescent fixtures fed with SJO type whips.The area is a dry location,a warehouse.The owner wants more lights put up. My question is about the SJO cord feeding the fixtures.Usually I use MC w/ stranded conductors to feed chain hung fixtures.I'm looking at 410.67(c).I would think the SJO cord is a violation. Any feed back is greatly appreciated. ToHo
