Adding in new construction can lights that come with push in connectors.

Rather than using the old yellow cap twists, the connectors have 4 slots and I wanted to know if I can just run a line from one light to the next using these connectors, or will that act as series?

  • Is this 14AWG or 12AWG, and how big are the boxes on these can lights? – ThreePhaseEel Nov 21 '20 at 23:23
  • 12AWG, boxes are about 3x5 with roughly 6 punch outs. Only one wire will come in and one wire out. I was just unsure if these push in connectors are supplemental for splicing a line and using a twist. – pstatix Nov 21 '20 at 23:28
  • Are the boxes marked with a volume though? – ThreePhaseEel Nov 21 '20 at 23:32
  • @ThreePhaseEel not that I can see, but each push in connection has 4 slots (all 3 wires). Assuming there is no volume issue, the question is whether or not these push in connectors are analogous of the older twist caps. – pstatix Nov 21 '20 at 23:38
  • @ThreePhaseEel these are the assemblies I am working with. – pstatix Nov 21 '20 at 23:39

"old yellow cap twists" - if you hate the things then use something else.

However you should hate the old ones. Old wire-nuts aren't very good, or to be more precise, newer ones are better designed. I throw away all old wire nuts especially Scotchloks.

The other reason to hate wire-nuts is if you have not learned proper technique. If they don't firmly hold together by themselves, you're not tightening them enough, or wrong-size nut for that many wires. I stock yellow and red, that covers just about everything.

Never, ever tape wire nuts. Or to be more precise, never need to tape wire nuts. A proper splice must easily pass a "pull test" (hold nut, yank each wire one at a time).

"Backstab" connections on receptacles and switches are known to be unreliable. Some here will vouch for the stabby splice, but keep in mind those "came free with the lights" which isn't the highest recommendation in the world.

As long as you connect white to white and black to black you will have a parallel circuit.

only thing to watch out for is how many lights you string together. your circuit may already be overloaded.

if you have about 12 to 16 lights on a circuit you should not add anymore.

  • Circuit is 6 at most – pstatix Nov 22 '20 at 1:26

    You can easily run 120 (10W LED) fixtures without overloading a 15A circuit. Beware the rule of thumb that may be out of date. – Ecnerwal Nov 22 '20 at 2:30
  • @Ecnerwal tell that to an inspector. any type of light may be installed in the future. you can't assume it will always be LED. – RadioSpace Nov 28 '20 at 14:41
