We've used both, and I've been less than satisfied with the Buchanan
crimp. I rate it better than wire nuts, but not near as good as
Polaris. Polaris type connectors have a separate connector for each
wire, so each wire's connection is independent, like a buss bar. The
wires can easily be removed, reinstalled, retorqued, and its easier to
check voltage without disturbing the connections.
IF you look at an outdoor rated wire nut (or the Polaris), its filled
with goo, and has an extra fitting to keep the goo in, and moisture
out. The Buchanan does not, so it really looks like an indoor rated
connection only to me.

Wrenchers,
Some point back we transitioned from polaris lugs to buchanan
crimps/caps (doping our wires in noalox) for our jbox splices. I know
there have been a few conversations on here about this. Seems like a
much more robust connection than anything we have used prior. But now
we have an inspector who isn't in support of using them for
outdoor/damp locations. To be fair (although it seems like a far
superior connection) Ideal doesn't have documentation to support
outdoor use. I know a lot of folks on here have had solid/long lasting
results though. In any event, we may have to transition away from
buchanan crimps and wondering what you all recommend as your second
(or first) choice? Or if anyone has experience with supporting this
application when dealing with inspectors? Do we go back to polaris
lugs? I know there was a conversation a while back about failures with
those...
Thanks for any thoughts.
