One other key to success with any splice method is giving the installers
frequent training. Every few of months we bring some wire, wire nuts,
strippers, and terminal blocks to our safety meeting

copper split bolts wrapped with insulating then regular tape are the way to go.

I agree with Bob-O, wire nuts are not the best choice for DC connections,
for all the reasons he mentioned, but SMA claiming that wire nuts are
causing arc faults seems like a long shot at covering up an arc fault

I've had butt splices fail, due to a ratchet release type crimper that
didn't pinch the wires tight enough.
I now use a good old Klein crimper that puts a big indent on one side. The
problem with this however, is that it damages
but in this case it sounds like I may not.
Just my $0.02
