When using acronyms,please use entire phrase at
least once, such as "Permit and Resource
Management Department (PRMD)." Those of us who
don't live in Sonoma County (or even California)
might not know what it means. This one readily
showed up with an Internet search. Some of the
acronyms used on the list aren't so easy to find.
Thank you,

We are getting some questions from PRMD some
questions relating to 690.8 here is what we have
3 modules, 260 watts at 9 amps ISC each module is a single string which
goes into a MNPV6 disco/combiner/disconnect
combined to a 30 amp breaker, it is being
replaced with a 40 amp per 690.8(A) 1
leaves there and goes to a 32 amp disconnect in our device.
here is where it gets interesting
690.8 (A) requires the 40 amp breaker but reading down to 690.8 (B) 1 we
need to up-size to 50 amps (no 45 amp is non available)
We also have added the 63 amp GFI in the disco
we have also moved up from # 10 wire to # 8 wire as a result
All this seams over kill for three modules,
there are 2 exceptions but PRMD do
not feel they are relative.
Is the Midnite solar disco considered an
assembly with the bus bars inside if we install the breakers
Any ideas would be helpful
Jerry
