Help! !30 amp main, shuts off on shore power.

[Blackdiamond]

I was just at the Colorado River, extreme heat. Plugged into 30 amp shore power, both a/c running and it would trip my main breaker inside the coach. Also running 1 a/c and the microwave it would trip the breaker.

As a work around I ran 1 a/c all day (97F inside) and would run the gen whenever I ran the micro and then at night I ran the gen to cool it down(to run both a/c) until I went to bed. then shut off 1 a/c and back to shore power.

I have an Intellitec ECC, could it be bad or bad power from the pedestal? I know every time the breaker would cut out I would have to turn off power at the pedestal before the breaker would go back on.

What and how do I check? Thanks!

That's drawing too much power off the pole. You probably had other incidentals running also. My advice, turn off one AC, close off the opposite end of the rv so the end you are in will stay cool. Every light or appliance you turn on will cause more heat.

There was probably a lower voltage than normal coming from the shore power. I can only run one a/c from my 30amp. plug. Do you have a surge protector that reads the incoming volts and amps?

probably low voltage at the power post.

2 airs in a 30a coach? Don't see that every day.

With everyone running air, voltage drops, breakers break.
