Have you ever wanted to run a 240V Mini-split heat pump in an RV? There is a way. Most RV's are running 120V only appliances. So how do you run something on 240V, while staying safe. Remember, you can't short out 240V lines when using adaptors for 120V shore power.
Photos: I'd like to thank 3 people for helping me with RV photos. Thank you to Mark, Mark, and (anonymous), for your help.
The answer is to use a transformer. I bought a used one for $50. Check around locally on Craigslist, Ebay, and Facebook Marketplace.
