Gord, those Ancor crimpers both look like what I call (perhaps wrongly) "staking" tools, just pressing a stake into one side, not making a "proper" hexagonal crimp or other compression
on the whole barrel. That's really UL approved??
The ring fitting...well, a 5mm wide hole means a big ring. I'm glad there's room on THAT breaker but it would stil be too big to fit on many other terminations, leaving the old question of "Oh, sure, that's gonna go into WHAT?"
Rick, last I heard the hammer devices were no good because you have no idea "how much is enough" so the result will be inconsistent.
