I recently purchased the Advent Air RV Air Conditioner - 13,500 Btu. And Im putting it into an enclosed trailer I was wondering if you could recommend what amp breaker I use for the unit?

You'll want to use a 20 Amp breaker for an 13.5K BTU Advent Air air conditioner. If you'll be adding any more AC loads to your enclosed trailer now or in the future, I recommend looking into power centers like part # PD4135K. These will give you an AC breaker panel, a DC fuse panel and a converter to charge your trailer batteries if you are hooked up to shore power.

I've attached a link to our selection for you to check out. You'll notice different Amp ratings for the converters. The correct Amp rating that you will want will depend on the amp hour (Ah) rating of your trailer's battery bank. You will want to choose a power center with an Amp rating that is about 30 percent of your battery bank's Ah rating. For example, if you have a single 100 Ah battery, then you will want a power center with a 30 or 35 Amp converter. If you'd like any more information on all of this, please feel free to reach out and I'll be happy to help further.
