Power rating - mixed star/delta/single on one board

[Engineer54]

If you can’t control what’s to be plugged in to the unit all you ca n do is put a “Maximum loading” label on it. After that it’s out of your hands.

That is all most manufacturers provide, a maximum rating!! Don't think i've ever seen an ''in-depth'' rating plate breakdown!! lol!!

So what do I put on the maximum load label?

You put your fixed loads with or without diversity depending on YOUR design allowances and how the unit functions, PLUS a maximum additional loading which you have allowed for to be connected in YOUR design calculations.
