There are tables. I don’t have convenient access now. Others here do. Give them some time to respond.

6 sets of 400 kcmil XHHW would get you 1620 amperes.

You can view the NEC for free on the NFPA website. You do have to register with an e-mail address and it is not very user friendly, but it is usable. www.nfpa.org/70 click on free access and then select what edition you want to view.

I admit I'm a bit concerned that a "Senior Electrical Engineer" asks:

Once your conductor becomes necessary to be more than 500kcmil (copper or aluminum) it is almost standard to parallel however many conductors is necessary to get what is needed for ampacity.
Use of 310 ampacity table I would guess is one of most commonly used parts of NEC.
