Thank you for explaining

When we built we ran a single run of 14ga to a lights-only circuit in the kitchen. Codes made us pull it and put back 12ga.

Point being, backstabbing isn’t really even an option in my county. Unless there’s a 12ga backstab outlet I don’t know about.

Backstabbing is for 12 awg if you're brave enough.

I'm no electrician but played project manager for many.

Speed is money, pass inspection then make it through warranty, that's all that matters! Thus backstabbing happens.

Screw connection and single strand twisted with a wire nut cap in my house. Prove why I'm wrong.

Multi strand is a different animal.

Point taken, but the thread was about static wiring devices & not vibrating motors.

Taping wirenuts in a peckerhead, IMO, is to help prevent/ reduce the wirenut from loosening over time by forcing it to not spin free by tape friction against the wires. No other logical reason I can see. Also, there are moar better connection methods for motors depending on the motor such as male/female disconnects (stak-ons), ring terminals fastened together with machine screws/bolts n nuts then insulated with cambric/ rubber insulating/ 33 or 88 tapes, insulated lugs (Ilsco, NSI, etc...)...



...won't say that I haven't wirenutted/taped motor leads and also replaced them due to coming loose too

A little wallering out of the hole and bam! #12 can be backstabbed...

I'm a crimp sleeve and wrap cap kinda guy. It doesn't have any way to vibrate loose. I was working on a sawmill trimsaw a couple years ago that was ring terminal/bolted on the 15hp motors and a bunch of them were loose and only a couple burnt up. I guess the cambric and rubber squeezed them tight enough. I clipped them off and used crimp sleeves and either did wrap caps or cambric/rubber/88. I've also seen oodles of cooked wire nuts, but it's usually reds or red/yellows on tiny wires.

On bigger stuff I use bronze split bolts then wrap with cambric, rubber, then 88. I like Polarises for speed but I've seen too many of them burnt up to have a lot of confidence in them anymore.

I call them battleships as well.
I thought you were a union guy and wanted to use the 'proper' nomenclature. I actually had to look it up before I posted it.

It's like screw-in drywall anchors; I've heard them called tornadoes, hurricanes and auger anchors. Depends...

If it's electric, it can vibrate loose.

When I worked on distribution stuff you'd be amazed at how often I'd find loose stingers on primary. They're torqued on installation then vibrate loose over time (time, depending on which lineman torqued it...) . Usually if I identified a buzzing stinger my clients would send a crew riki-tiki to fix it. The buzz - if it was loud enough that I could hear it from the ground - was a flashing arrow sign saying it was about to become an outage, and they preferred fixing those things 9-5 instead of 3am.
