(3) 2-Pole, apparently 125A, ea., linked together by common trip handle, feeds a wireway which is tapped to feed (3) disconnect switches that feed (3) ACUs.
The question is: Does this "field-rigged" 6-Pole disconnect meet the requirements of Arts. 230, 430 or 440? Tried uploading a picture but the site won't allow the size of the file: 200KB.

You could get by (and be better served?) with three independent two pole disconnects at the lower current or a single high current disconnect on the supply side.

Is the breaker actually 3 separate two pole units or is it a factory assembled three pole unit that happens to utilize two spaces of the bus per pole? Such a beast is common for panels that normally accept "miniature" type breakers in situations where the rating is over 100 amps. Common in the fact that is all you will find if you need over a 100 amp breaker, uncommon in that you hardly ever see them in the wild.
