placment of inverter breaker [RE-wrenches]

[Mark Frye]

Darryl,

The way I read this:

 - The sum of the breakers can never exceed 120 % of the rating of the buss.

 - If the sum of the breakers is less than or equal to the rating of the
panelboard ( 0 to 100%) the breaker may be positioned anywhere on the buss.

 - If the sum of the breakers is greater than the rating of the panelboard
(101 TO 120%), it must be positioned opposite the main and a label affixed.

HI all
new code 690.64 B7 does this mean that as long as I
have a breaker at the opposite end of the panel board,
I can have a breaker rated at the busbar rating?  Or
just that I must always place my inverter breaker at
the opposite end and the old 20% of busbar applies?
Thanks Darryl
