industrial application, inside of a seacan shipping container. I'm not sure where to even start looking in the code book.
The customer wants us to run qty=(4) 480VAC multi-conductor cables in wire mesh basket tray, which I'm not extremely knowledgeable about it yet.
  • Is there a minimum height requirement?
  • is a cover/lid required, if so, when?
  • not sure on this one since its an 'open' cable tray. But I think the cables have to be separated by the same distance as the diameter if said cables. EX: scale is 3/4" so need a 3/4" space between it and the next cable.
    • but they can be touching if we derate them?
  • is a barrier required to separate it from 24VDC control voltage and/or ethernet communication cables? assume all cables have 600V rated insulation.
  • And anything else im not thinking of at the moment and listed on the list of questions?
not exactly sure on cable part #'s yet, but will likely be something like this
XLP Insulation, PVC Jacket, 600/1000V UL Type TC-ER, 90°C

Start with the cable tray article. Then look at mfg literature on the wire basket, is it listed for that heavy tray cable. grounding, etc? You might be better off with the standard B-Line tray as it has all the accessories like hangers, drop outs etc
