Combining array strings before the combiner panel

Postby Johnt on Tue Aug 01, 2017 2:22 pm

If I have a 2 string array, can I splice the 2 strings together to an appropriate sized feed conductor and then terminate to the combiner panel ,or does each string have to be individually run to the combiner?


String NEC x1.56= 10amps
Array NEC x1.56= 20amps

Wirenut the 2 strings to a #8 (sized for line loss) and land on 20a combiner breaker. Permitted by NEC or not.

I want to be code compliant for permit.
