Difference between these two push-in wire nuts?

jailbird371

Maybe I'm just dumb, but I can't quite figure these 2 out. I'm wiring up a 6 zone Lutron Grafik Eye QS and I need to have 7 12ga wires connect for the neutral and the ground. These seem like the best way to go, just because the number of wires as well as the limited room in the box.

This one says for "grounding terminations only"

This one says for "non-grounding terminations only"

I'm not following why there'd be a difference. Why can one only be used for grounding only, and one for non ground connections?

Maybe I'm just reading it all wrong.

Because one is green signifying ground.

Thing is there is nothing in the code to justify this.

I think it is a marketing thing.

Neither Wago or Ideal make any mention of needing a different connector for grounding vs non-grounding. Could have been written by someone that thought the green could only be used for grounding.

That is poorly worded. The first sentence is about wire nuts and saying that wires can pull out of the nut.
Now if you pre-twist------------------------------------------

Completely missed that....

BTW...I consider wirenuts a better product to the push-in connectors. Reminds me way too much of a backstabbed device. Also, I thought I remember reading that the push in connectors are a one-time use item. If you have to take any wires out of the connector, you have to replace it.

Sorry, I know I just opened "Pandora's Box"........

Are you sure that the green one for grounding terminations does not have exposed metal? This would be unacceptable for use with ungrounded conductors.

Two or more wires, even pretwisted, won't work in one hole of one of these push in connectors even if the hole was big enough. The spring clamp inside will not hold multiple conductors, even pretwisted, in good contact.

From looking at Wago's website only the color of the insert looks different.

The Ideal ones say you can reuse them. The wires pull out pretty easily if you twist them in the connector, but you are supposed to restrip any wires you remove that way. I have used them in some crowded (not overcrowded) boxes, but I do think regular wire nuts are more secure.

Ravenworks

I agree with you guys in the marketing,I do not agree with the manufacture saying they can be used on stranded wire,it's disappointing to say the least.
I would venture to say they would be good for lite loads but would feel better about wire nuts for high load circuits,correct?

Jim Port

They are rated for the circuit size so I don't see the concern about only on light loads.

Fair enough

a couple of "big blue" wire nuts should fit in the box no problem with the graphic eye. unless you want to buy youself a soldiering iron and some heat shrink there's not many connections that are going to top a pretwist wire nut connection.
