NEC 240.91(B)

[OCPD]

Hello Everyone,

1. Can "Part VIII Supervised Industrial Installations " be applicable to a hospital which do match up with the article 240.2 for supervised industrial installation?

2. The reason for asking this is at the hospital a 1600A circuit breaker (at generator) is feeding 4-sets of 500MCM (1520A at 75degC). I was wondering if the article 240.91(B) is applicable here or not?

I do not see a hospital fitting the criteria of the definition.
