Title: Running 2 AC units in my 30A rig
Post by: pz on July 17, 2017, 03:39:53 PM
Actually the original RV A/C unit plus a portable heat pump we're using as the additional A/C unit.

My method is not exactly pretty, but it required minimum work to get it operational. There are now two ways to connect the second A/C unit to the park power supply:
I left the original 30A circuit RV completely alone and added the second power inlet to serve a single new socket inside the rig (in the same area as the power inlets are located). That socket is protected with a 20A marine breaker, and I deliberately chose a round socket so the wife will always know that anything plugged into the round socket is on the new circuit.

We now plug the 12,500 BTU heat pump into that dedicated circuit, and have the vent for the portable unit ducted outside the window where the unit is located.

We tried it out on a run to Orifino Idaho on the Clearwater river where the temperature was 105 degrees.  We were very comfortable in our newly equipped rig with both cooling units running.

Clever... I like thinking outside the box.

I think that's darn clever. Looks like fine workmanship to me. I especially like the way you vented it out the window.

Thanks Kev - I'm headed to the Columbia Valley one of these days soon, and now I don't have to listen to the missus giving me a bad time for an under-cooled rig  ;D
