Default 200 amp sub panel

I have a job coming up where I need to install a 200a, 277/480v three phase sub panel. It will have its own 200a breaker in the MDP and a conduit run of 150 feet. Am I right in using 3/0 copper for my feeders and neutral and 4 copper for my ground? Thanks!

Fairly new. I have done more residential work than commercial. I'm looking to make sure I am selecting the right size wire for this job.
