Re: corrosion protection of romex connectors
What you are asking is not a NEC requirement. Corrosion protection of field cut RMC and IMC threads is, currently in the 02 code it only has to be an approved product, the 05 will require a listed product, the only one I know of is T&B Kopper Kote, it "gets home before you do". I use Burndy Penatrox E, same stuff but its in a tube.
