I understand from 430.62 the next higher size of the breaker shall not be permitted & we have to go for the next down size. This is acceptable in ratings smaller than 800a, what about the ratings over 1000a?
e.g. we got 1500 after applying 430.62 rule & the standard breaker size either 1200a or 1600a, which one we have to go for?
