Marrettes (twist caps) like to break off the ends when you re-connect them. The solid core wire only takes a couple twists before it fatigues and breaks. If you do a new one, or have to strip the wire back because you broke off the last one, I’d definitely change to these. They’re much more reliable, don’t break the wires and you can see when they’re inserted correctly. And when you only have so much length in your wires in the box, you want to preserve what you have so you don’t have to open up the wall and lengthen it, and doing so isn’t to code anyway if you don’t put in a junction box.
I’ve DIY’ed my own electrical for decades, and I change to these whenever I can now. It’s like changing from copper to PEX at any chance for plumbing, superior in every way.
I can see how these are easier to use, but why would you replace existing twist caps?
Because I’ve had them slip out of twist caps before, especially on ceiling fans with three wires going into one cap. I just don’t trust em, y’know?
I heard you’re supposed to crush them with needle nose pliers so they don’t slip out.
yeah no dont. these are great
