A: 8 - 32
A: That is all this type of connector is for. Non-Metallic. The reason for this is the same company makes a very similar product that does MC and Romex.
A: The connector itself it metallic but is intended for use with NM cable.
A: It is to clamp non-metallic cable (Romex).
A: MC or BX style (coiled step jacket) requires a different clamp, basically looks the same, but has a jacket retension wall inside the clamp, so as only the wire comes through, and not the steel jacket
A: The clamp is made of metal, but it is described as non metallic because it is used to secure wire without a metal cover as in BX wire.
A: Although the clamp is indeed made of metal, it is designed for clamping non- metallic sheathed wire, it's just the industry way of describing it's things in a quick way. Rather than saying metal clamp for non metallic sheathed wire..... In the same way ( to some degree) a 2x4 in lumber isn't actually 2x4 inches after getting milled. But it's still considered 2x4. Rather than a 1.5 x 3.5
A: That would have been my answer, it's used for non-metallic cables, Romex. A better description would be 2 screw romex connector.
A: I agree, it's a bad description.
A: It is designed for 1 wire. It will hold two 12-2 or 14-2 Romex wire.
A: These are only listed for one Romex wire. Anything more will and can pinch the cable and creates a fire hazard.

A: 1-14/2,or 1-12-2,or 1-12/3,or 2-14/2

A: One 12-2 or one 14-2 per clamp, and is that the same question
