The crimps you see on submersible well conductors would be fine. It is
an irreversible crimp with silicone in the shrink tube insulation. The
problem is you need the right tool to make the crimp and the one for
6ga wire is probably $100. I did see a guy who went to work on a 36"
Harbor Fright bolt cutter with a grinder to make a big crimper. It
seemed to work OK.

A related sidebar Q? --

Is there anything/any way to repair knicked insulation on an
underground feeder?Â* Or just go ahead and cut to use the splice kit?

I managed to cut insulation on one side of feed to house during the
work around the old foundation when discovered the conduit out bottom
of outside junction box wasn't nearly as deep as had presumed Dad
would have left it...and, unusual for him, there was virtually no
slack in that line to be able to really do a good job wrapping it
(...both of which make me think he must have sublet that work instead
of having done himself--just not characteristic of something he would
have done on own. Â*Â*He worked on remodel/refurbish of grandparents
house for 5-6 years and had to take off for real job of farming for
extended periods during summers so let out some of the work).

I sorta' cobbled a tape job w/ some of the cold-vulcanizing tape
followed up w/ electrical tape and then covered that with a good
coating of one of the liquid rubber products as water seal -- then
covered it after dried w/ another tape wrap.Â* We'll see how long it
holds...

Was more than unhappy when discovered what had done...


3M makes a couple products that may be useful

https://www.3m.com/3M/en_US/company-us/all-3m-products/~/All-3M-Products/Energy/Electrical-Construction-and-Maintenance/Wire-Cable/Splices/Low-Voltage-Splices-1-kV-/?N=5002385+8709319+8710679+8710904+8711017+8717973 +8730567+3294857497&rt=r3

are splice kits.
Some of them have a split plastic form that you snap over spliced UF (or
whatever). (Magic crimps not required.) There are 'funnels' that snap in
the ends of the form. It comes with a bag of epoxy - 2 part with a
partition in the middle. You pull the partition apart, mix the epoxy in
the sealed bag, and pour it in one of the 'funnels'.
IMHO the nicked wire should be separated out some so the epoxy can make
good contact with it.


https://www.3m.com/3M/en_US/company-us/all-3m-products/~/3M-Scotchkote-Electrical-Coating-Fd-15-oz-Can/?N=5002385+3294648449&rt=rud

Scotchkote liquid coating. Says for coating 3M vinyl tape for direct
burial. I would like to get some on the nick under the tape first.
Should be better than what you used.
If this was to be inspected I would like to see better instructions.

I have used both of them.
Both have a mystical ability to get on everything, including
screwdrivers in your basement.

Thanks...the 3M product particularly would be handy. My looking and
found it...

What kind of shelf life does it have, you have any idea?

Certainly listed for purpose is good; I think the fix I used will
probably last my remaining lifetime as that stuff is pretty resiliant.
Iffen I were ambitious-enough, could uncover that location and clean it
back up and add some on top.

I do have a spot in that feed to the waterer in the south lot that still
need to get back to and splice--I tapped into the other side of the 240
feed to get it back on last winter but never got to fixing the other
side--if this side were to fail, I'd be stuck which would not be good
come winter time and need the water.
