No doubts about it. RT connectors to a 4S deep and 4S blank. Laughable.
Then you would have a sore belly from laughing around here.
common job specification around here is the mandated use of steel compression fittings on all EMT installations. The fact that they are in dry locations and entering NEMA 1 enclosures has no bearing on this job spec.
I have been told that these fittings provide better bonding but I have no idea if that is a fact or urban legend.
Also when you run EMT for fire alarm systems in RI you must use steel compression fittings with insulated throats.
Can be a real bummer if you do a whole job in set screw fittings only to find out compression fittings where required.
And no it did not happen to me but I do know people it happened to.
