Wrenches,

I'd appreciate some help in determining when we need fuses or breakers for 
parallel strings. For some reason I thought that two strings in parallel are 
OK, but that for three and above we need to use the appropriate combiner box 
with breakers or fuses. This feels too vague--especially as I am now being 
asked to review and approve systems (for the Energy Trust of Oregon) with 
more than two parallel circuits.

Please shed some photons on this--when do we not need and when do we need 
parallel string fuses or breakers, and where does this correspond to in the 
code--or make common sense?

Thanks so much!

Gary
