Do I dare say these I do pre-twist and never had an issue.

I use split bolts almost daily for Utility Side, and use (Used) them very frequently for other side of the meter. A good pair of pliers and the right size socket a split bolt is simple to install. 1 1/2” tape makes short work of the taping. I wrap mine with a layer of rubber tape first, then follow it up with vinyl.
FWIW, the only split bolts I have ever pulled off that were failing were on the service drop at the weather head, and they were the aluminum split bolts
Agree... I don’t have a problem with big blues either.
I don’t care what kind of termination is used, if done wrong it will fail eventually.
Mine gets a half twist.

I’ve seen them burn up in a tankless water heater installation and a large motor .
Im selective if its a heavy load draw.
Small Polaris taps are $12 Each.
But i know im not getting a call back.
Im not opposed to them just selective and cautious..

"Back in the day", long before multi port Polaris and the like connectors were invented, it was common practice to put as many conductors as would fit (even mixed sizes) in a split bolt. Don't remember any failures.
I always used glass cloth tape as first layer especially if I thought it might be me that had to re-open it later.

It's all about the story.

About only ones I seen fail were used with aluminum conductors, even when designed for aluminum.
Bad neutral problems or even lost ungrounded conductor and you see split bolts on the overhead distribution....usually means look there first. If all copper maybe not as high on the list though.
Isn’t that the purpose? It’s all about the interaction and mountain making....

Got it done that's good. Looking at the photo without doing a calculation I'm guessing that the conduit is too small. Now if you call it a sleeve?
Kind of what I was thinking...
I think the two flat cables hurt him

How do you do a pipe full calculation for those two conductors?
I remember doing it for NMB wire 12 -2 But not this particular wire

Measure the width of each cable and then use that number as if it were round to convert into circular mils. You're allowed 31% fill with two conductors.
