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.........

Luke, Mick Jay.....Thank you for the feedback..I just ordered a set of
the cub crimpers...I think it is going to be a useful addition to our
tool chest.
What prompted this is that we often solder our ring terminals on but
it tends to stiffen the copper wire.....We use alot of the Midnite
panel mount breakers and the 300VDC breakers still have the really
chincy terminal posts which break off with just the slightest twisting
of the wire....Over the years Outback Power also used those breakers
and we have piles of those brand new crappy breakers which have a
broken terminal post....I noted some of the single pole panel mount
breakers have a sturdier terminal post and this problem is going
away....I am hoping this can happen for all the panel mount breakers
these manufacturers sell.
Made me realize a high quality crimp without the stiffening of the
wire will help reduce this problem. Those breakers are expensive!
Thanks for the advice!!

Hi Khirpa,
We use a high quality mini hex crimper with rotatable dies for
#8-1/0 AWG. It is basically a miniature version of the Hex-Crimp
battery lug crimper sold by Quick Cable. The one I have is older
and no longer has the manufacturer label, but I believe it was
marketed as a Cub Crimper. A quick web search shows that there is
still a similar crimper sold under that name. At any rate, I have
been very pleased with this crimper, and I'd recommend it.
Best,
-Luke
