Branch feed & disconnect meands determination for refrigeration loads

[ServiceMAN01]

First of all, this being my first post I just want to say that I have been using this site as a resource for a long time. Thank You to everyone?
I have been approached by a friend who needs to have roughly 5 tonne of refrigeration (walk-in coolers) in a building that has never had them before. And while I have done numerous residential and industrial branch feeder installs the current 430 sections are seeming cyclical with regards to sizing overcurrent, conductor, and disconnect means.
The building appears to have 240v, 3ph, 200amp existing, and there appear to be no locally over riding codes.
Can anyone help out with this:

1. Two refrigeration units total:
   1. Nameplate:
      1. Unit 1 - Volts: 200/230, 3ph, 60Hz, LRA 85.00
      2. Unit 2 - Volts: 230, 3ph, 60Hz, LRA 110

I am looking for branch circuit ampacity/conductor size, overcurrent for both main panel & local disconnects. And possibly grounding?
Any help would be greatly appreciated.

NEC Article 440 covers Air Conditioning and Refrigeration equipment. It is a short article (less than 10 pages). I would give that a quick read and see if you have any questions after that. I would look over article 215 and 220 as well.

Need more detailed info... preferably complete electrical info on the nameplate, especially minimum circuit ampacity (MCA) rating, maximum overcurrent rating (MOCP, and whether fuse or breaker is specified), HP rating if any, rated load current (your post has LRA, which is locked rotor current... perhap you meant RLA).

As fifty60 mentioned, refrigeration units are covered by Article 440. Though it may be shorter than 430, there are instances where 430 come into play... but I'll not speculate on those just yet.
