This code section should account for 100% rated breakers being used.

690.9(B) has an exception for this, but 705 does not accommodate this.
690.8(B)(1) Has an exception for 100% rated breakers as well with similar language. I think this should be added here.

I also think wording for switchboard/switchgear should be added where applicable to (a) thru (d) since some of these sections clearly only apply to panelboards, while this code provision could be used on larger equipment.

As an example, I have 1440A of PV current, a 1600A 100% rated breaker, but yet I must account for 1800A on the bus which will not exist.
