No doubts about it. RT connectors to a 4S deep and 4S blank. Laughable.

A very 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. [Linked Image]
