Sq D as combiner box [RE-wrenches]

[David Palumbo, Independent Power & Light]

Are Square D breakers considered suitable for series fusing pv array?
If so, why not use a rain proof Square D load center as the array combiner
box?
You would still have a Heinemann breaker, or RK5 fuse, or Class T fuse in
your DC disconnect box for catastrophic protection.
Square D breakers are available in 10 amp single pole and that would be an
appropriate size for many modules.

Recent quote from CED QO612L100RB $49.68, QO816L100RB $ 62.88, QO12L125RB $
96.05; single pole breakers run about $ 7.75 for 10 amp.
