[RE-wrenches] Buchanan Crimps in Outdoor Boxes

[Ray]

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.
