Feed In Breaker Sizing
What options do I have to feed in large arrays into residential main circuit panels. Most residential are only 200 amp and the array calls for 50 amp feed in breaker. What is the sub panel feed in rule. Sub is feed by a 70 amp at main, sub panel is rated at 125 amp, my solar feed in breaker is a 50 amp, so does the breaker feeding the sub panel become a feed in breaker also to the main?
