We, with the support of a fellow IRV member, wired a separate line from the front a/c unit to a double pole DC controlled switch, which enabled the circuit to be transferred to an outside power line to the 20 amp recept at the power posts in most campgrounds. The use of the double pole enabled the power and ground to be transferred which helped manage the ground fault recepts.
Works great when we really need lots of A/C. (Draw a schematic of the current system and then insert the double pole switch in the circuit to move the power from the current circuit breaker to the separate outside line). The rear A/C is still managed by the Inteliteck energy system. Both now work not connected.
50 Amps for a 30 Amp system.
One issue is that lots of RV campgrounds have removed their 20 Amp recepts. We then use a 50 Amp to 30 Amp dog bone for the main power and a 30 Amp to 20 Amp dog bone for the front A/C unit.
PS: both of our A/C units are 16,000 BTU Brisk Air II units.
