My coach has a Precision Circuits Power Control System; it is a very sophisticated, smart, system. This system routs and monitors power throughout the RV regardless of source, generator or shore. It works with the Magnum Inverter to reduce battery charge rate prior to shedding loads. It will shed non-critical loads during high peak loading. Here is one of its self proclaimed features, ?Monitor and Manage total RV current (amps) to avoid nuisance circuit breaker tripping?. This is where the system becomes too smart.
We camped at a camp ground that had only 30amp service available, not a problem I thought, it was hot outside, but I have run 2 A/C units on 30amps, on a previous coach, without a smart Power Control System. Just monitor your amps, stay at or slightly under 30 amps and you are good to go. If I drew too much current the trusty circuit breaker on the shore power pole would let me know. It has been my experience you can run a bit over 30 amps and still not trip the breaker, less that 30amps is preferred, but a slight bit over 30amps for short periods of time will not trip the breaker.
With a smart power control system running the show, this being loose with an amp or 2 is not an option, the instant the smart system detects 30 amps, it sheds the second A/C unit. 2 A/C units can run on less than 30 amps, after initial start up, but if the smart system detects a battery system in need of charging, which is a higher priority than my 2nd A/C unit, the A/C unit is ?shed?. Of course the big new RR is always drawing its 6 amps which compounds the problem.
We love our Tour with 100 available amps, with exactly 30 amps, it is a hot box.
