We always used the rule of thumb from the Ananda power centers, Trace, 
etc.: 2/0 cable gets a 200A T fuse or 175 A breaker, 4/0 gets a 400A T 
fuse or a 250 amp breaker. If you look at the trip curves it makes more 
sense. TheT fuses definitely trip faster (lower current) than the Heinemans.
I ordered some 300 A fuses once through Summit Electric they were over 
$50 a pop. I quit looking at the in between sizes after, and all has 
been well since.
