NEC 2014 section 705.12(A) says sum of the ratings of all overcurrent protection devices connected to power production sources shall not exceed rating of service.
I have 400A fused main service disconnect AC solar and 600A fused main service building disconnect. Rating of service is 600A.
Do I count 600+ 400 or just look at 400 for sum of all overcurrent devices power production source? Utility overcurrent fused disco count?
