[RE-wrenches] 30 amp disconnect/40 amp breaker

[Greg]

Fellow Wrenches,  I'm having a discussion with a utility engineer 
regarding the following situation:

Installing a 6kW inverter that has a full rated output of 25 amps. 80% 
of 30 is 24.  That means to me I need to go up to a 40 amp breaker.  I'm 
running #8 (continuous load 25 x 1.25 etc.)
The engineer believes I should use a 60 amp disco since it's on a 40 amp 
breaker.  My thinking is I can use a 30 amp disco since it can not 
produce more than 25 amps ever.

Do any of you have a reference that shows what I'm doing is okay? Not okay?

Thanks again,
Greg Egan
