800Amps Circuit Breaker with (2) 500Kcmil Lugs

I googled that erikson number and they dont say whose breaker they use, but they do say "MDL breaker" and googing that looks like an eaton M frame MDL3800. In the Eaton catalog that is showing as the std lug being a 3/0-400 3 conductor lug. Erikson for some reason apparently isnt supplying that, but the part number for that lug is TA800MA2, should be able to swap it out (assuming I have inferred the correct breaker).

Edit: for those who are curious, in the Eaton catalog, the (2) 500kcmil lug is showing for a 700A max breaker.

How would that help you if two 500 s do not give you enough ampacity? Polaris and Panduit makes such connectors but I don't think they're going to solve the problem.

I'm not concern about the ampacity since the line side of this breaker uses 2 sets of 500kcmil.

Thank you. I'm waiting on the contractor now to see what he will say about changing out the lugs. I will keep you all posted. Thanks again

You know if worse came to worse you could always get three crimp on 300 lugs and two crimp on 500 lugs per phase and just bolt them together and cover the connection with tape and heat shrink. Beyond that Panduit or Polaris connectors work pretty well.

Would just be a whole lot easier to get the right lugs. In any case who ever specified this arrangement ought to be paying the freight.

Well it is possible that the line side is POCOS, depends on where the service point is. I suspect the reason for the "small" lugs is the POCO specs this thing and they are thinking more about how they would run 800 amps, not what the NEC would require - an oversight on someone's part.
 
Thank you all for the responses. The contractor has confirmed that they should be able to change out the lugs which make things a lot easier. Thanks again for your input!
