Hello,
Our company is building our first Class 2 Division 1 and 2, Group G machine. And in reviewing NEC 502, i have discovered that Liquidtight flexible nonmetallic conduit with listed fittings can be used. What we don't know and want to verify is "do we have to run an outside ground conductor to complete/continue the grounding". This is a spec one of our senior engineers believes to be the case. What we would like to have is verification yes or no - and where that spec might be written [as i have yet to find anything relating to it yet.] I have found fittings that seem to be rated for our machine, Crouse-Hinds - and they do not have an external ground lug.
thanks for any views and suggestions.
and thanks to MHF for all the help.
