How much romex fits...

... in a half inch nipple? Specifically, can I put two NM-B 12/2 cables in a half inch nipple on my load center? Two 12/3? Three 12/2? Do I need a special nipple?

I couldn't find info specific to romex in Ugly's, Wiring Simplified or the NEC.

Thanks.

Steve

Do you mean 1/2" box connectors for non-mettalic sheathed cable? Then, yes.

Sorry, just edited my post when I saw your answer. How about two 12/3? Yeah, this is unshielded romex with no conduit.

No, you can only put one 12/3 cable per 1/2" connector.

If you are indeed talking about a NM-B (romex) connector, the answer is that you may install how ever many cables the connector is listed for, subject to any local rules. What this means is that somewhere on the packaging should be a note that tells you how many of what size cables the connector may be used for. While most are listed for two 12-2 cables, some are listed only for one. There are also some that are listed for more but are a bit of a specialty item.

If you are buying the connectors out of a bulk bin at a hardware store you don't really know.

What the NEC says on the matter is that is not legal to use a product
inconsistant with its' labeling and listing
