ECN Forum Forums Code Related Discussion NEC & other Code issues Stranded use in recepticle terminations

Another trick that helps when terminating str to receps is to use a pair of needlenose to hold (squeeze) the wire tight around the terminal binding screw while tightening the screw. It helps keep the conductor from blowing out all over the place.

Massachusetts change. 110.14 (A)
"Connection by means of wire binding screws or studs and nuts having upturned lugs or equivalent shall be permitted for 10 AWG or smaller solid conductors. Where stranded conductors are terminated on and not looped through such terminals, the terminals shall be identified for such use, or the strands at the terminals shall be made solid." My question. Are the terminals on receptacles considered wire binding screws? If so according to the ul they are suitable for stranded wire and this article does not apply. I find it easier to crimp on a terminal anyway.

Scott I put up that MA amendment up before, that is when Don showed me the UL listing.

I have not had a chance to talk to a MA inspector about this yet.

It seems that the amendment is meaningless.

I do not use crimps as 99% of our work uses spec grade outlets with back wire pressure plate terminals.

Sorry for any misunderstanding.
