Questions about this item

What wire sizes and how many conductors can I combine with these yellow twist-on connectors?

Each connector accepts two 18 AWG up to three 12 AWG copper wires, with a maximum of four conductors and a largest single wire of 10 AWG.

Will the 600 V rating and 221 °F temperature limit suit the older 600 V NM cable I am keeping in the walls?

Yes, the connectors are UL listed and CSA certified for 600 V and a maximum operating temperature of 221 °F, matching that cable’s ratings.

How can I confirm a solid connection after twisting the wing-style connector onto the wires?

Tug each wire firmly — no movement should occur — and verify the zinc-plated steel contacts grip the copper through the polypropylene insulation.
