If I wanted to add a second shore inlet connector to service a possible air conditioner install , how would I configure the master breaker in the panel, or would I have to add a new master that could handle both 30 amp lines? or add a second "master" breaker as well as an additional 30 amp breaker for the a/c. Also, my original 30 amp line is wired to the Freedom inverter and then to the Master breaker on the panel. I assume the second 30 amp line would go directly to the panel and not to through the inverter/charger.

Thanks guys.
