50amp service(shore power) gives you 2x(120volt, 50 amp) circuits for a total of 100amps or 12000watts(120v x 100amps=12000w), your 12kw generator provides your power in the same way.

If your a/c and microwave are both running at the same time you are probably drawing close to 30 amps right there. Most properly working a/c units draw in the range of 12-14amps and a large microwave will draw the same, so add in a coffee maker (most are 600+watts or 5+amps) plus some other possible hidden loads and bang goes the breaker.

You may be able to move some circuits from the big panel but before I would do that I would try to confirm how much power your existing circuits are drawing, it is possible that your a/c needs servicing (clean the evaporator etc) as this will cause an a/c to work extra hard.
