Zone 2 a/c and aquahot breakers tripped?

Hi all.
I just bought this 2000 U320 and have it plugged in at home.
Voltage is excellent.
Any ideas why those 2 would trip?
Zone 1 a/c didn't trip. Got E7 code on a/c zone 2. Thanks. Ray

Are you on a true 50 amp connection (240 VAC between hots)? 

30 amp or 15 amp?  If either of these was anything else running when you started the appliances that tripped the breakers?

Do the breakers hold when running on generator.  They both should be on separate breakers. Did they both trip at the same time?

I'm on a 50 amp we have at home. Power is good. We stayed in our last bus almost 1 year plugged into it while having our house built.

I haven't tried running both a/c on gen yet. I believe they both tripped at the same time? Not positive. I reset the breaker to the zone 2 a/c and its running fine. I left the aquahot breaker off. It's parked. Were in the house now but I'm in Fl and it's HOT. I leave the air on 80° for the humidity.
