These breakers are 1200 amp. It's a square D gear. First lugs I ever saw like these.

Better to have it and not need it. Than to need it and not have it.

Not quite sure what I think about those...

It looks like screwing up one connection will cause both terminations to fail. Seeing as how we've had the same double-stacked lugs for years, I'd need convincing why those are a good idea.

They make me wonder too. Guess we find out the end of this month, when we do the shut down and power swap.

I don't see an issue.

Plus, Square D can do no wrong.

Used them plenty of times with no issues yet

So, you take out the top set screw, tighten up the lower one on the conductor. Then insert the upper conductor, install the upper set screw again and tighten?

No you back the top screw out a ways and then land the bottom lug first. The Allen shaft passes through the top lug screw.

They are for parallel conductors. Been around for a looong time.

Thanks for the input. Makes me have a lot more faith in the design.

They look cool, do you have to ferrule crimp the ends of the cantol or anything? Heres our latest, hooking it up the other end to transformer disconnect on Saturday.

Who puts warning stickers over vent openings.. come on..

I worked with them once awhile back. If I remember correctly the bottom lug allen is smaller then the top so you can turn the bottom without turning the top one.
