Preferred Splice

[Knuckle Dragger]

From my own experience: Overhead service butt spliced crimped connections have failed the most.
I'm not saying that it happens often but if there is a failed connection at WH it is a 95 percent chance it was crimped.

What other kind of connections are there? Around here both of our POCO's use crimp connections. The neutral connection isn't even covered and is completely exposed to the elements.

I suspect operator Error.

A round here the EC or the POCO will make the overhead connection. Usually the EC will.
Here are some examples of two used. The second one typically has a plastic snap on cover for it.

I suspect operator Error.

I would agree.
to keep it short: Use the right tool for the right job.
I don't crimp but I'm not against it either.

Overhead butt splices (especially the pre-insulated ones) usually fail for getting water in them and then freezing; this is the reason careful linemen try to align them horizontal. Although I know of no proof other then anecdotal that this makes any difference. Obviously user error can be a cause of failure also.

Probably because the correct splicing die or tool was not used.

Failure rate about zero.

so is what the old timers taught me Infinity
