Running Both Air Conditioners On 30 Amp System

I am looking for the Motorhome Magazine article that showed how to hook up both air conditioners on a 30 amp system (so they can both run at once) if 50 amps are available. In my semi permanent parking pad, I have 30 and 50 amp plugs. I believe the article ran earlier this year.

I have a 1997 Itasca Suncruiser.

    Hi,

    It sounds like a variation on the "cheater" cables that are sometimes used by 50 amp rv's when in a 30 amp park. The want a mere $700 bucks for it, including the installation kit. They get around the 30 amp main breaker by having a 20 amp breaker in their "box". I'd rather run a secondary shore power cord for say $30 bucks total?

    I use to have a 30 amp motor home. Under "just the right conditions" you could run both AC's, but that was rare, you certainly couldn't count on it. I did some research and found a box to install that allowed both AC's to run. I can't remember the name, but do some searching and I'm sure you'll find it. If I remember right the generator is wired like a 50 amp service so there's separate legs to each AC, and you split off one of those lines into this box and then plug into two separate outlets. I believe that's how it was, like I said can't remember, but it did work, and was somewhat easy to install.


    It's called the Power Solutions Dual Power Adaptor.


    The dual power adaptor was just what you're describing. It's just a way to run a secondary shore line from the camp pedestal to the second a/c unit. It's just a hard-wired way to do it without interfering with the coach power. I think they cost about $80. They are apparently out of business but it's a simple device to build.
