Whenever I run into a MBO MSP and I land our PV breaker in the SP that it feeds, then I often connect more Amps of PV than 20% of the MSP rating.
What Code reference would you use to support this tie-in method?
---------------
E.g.
#1
(E) 125A rated service with an (E) 2p125A main breaker only.
which feeds the 150A rated SP.
I tie 30A of PV into the SP.
#2
Most recently 2p70A MBO MSP and I tie 20A of PV into the 100A rated sub.
