Need help sourcing Insulated terminal posts

[bsaint]

I need to source some insulating post terminals. They need to be good up to 300 amps @ 10kw (its for a welder.) Ive tried grainger and digikey but either they dont have it or I am searching for the wrong thing.

Thanks.

Are you looking for lugs or something like a Dinse connector?

Try Mcmaster-Carr or Cyberweld.

I think you're looking for a "feed through terminal", "pass through stud" or "bulkhead feed through". Blue Sea Systems sells some really nice ones but they're only good for 250A. I forget who their OEM is on the studs.

With those terms though you can find quite a few 400A examples from LittelFuse, GEP, etc.
