[RE-wrenches] #2 -#8 AWG Crimpers

[Ray Walters]

The breaker post weakness came up on the list a couple of years back, 
and Midnite responded by switching to the sturdier post.  I haven't 
tried the 300 v versions though.  I also haven't kept up with what 
Outback is using, but that post design should have never been used on 
anything beyond stranded 10 ga.  They regularly had them on 80 amp 
breakers.  I still have to deal with this issue every time I work on an 
system older than a couple of years, so this is going to still haunt us 
for decades.........
