I worked on the service end in the RV industry for a few years. I have seen/heard of people running their RVs AC while plugged in to shore power on a 15 or 20 amp circuit. I will even admit to doing so myself a few times. I know many people and myself have never had a problem doing to. However, having dealt with repairing, and having talked with directly with manufacturers of both Dometic and Coleman; they say do NOT!! run your AC on anything less than a 30 amp plug it. It can damage the system and/or damage other systems in the RV. The most common issue I regularly saw from running an AC on less than dedicated 30amp power was burned out capacitors. If you are going to run on a 15 or 20 amp circuit I highly recommend installing a 'hard start' capacitor.
Like I said, I admit to doing it myself even knowing what I know. However, with that said, if I am doing so and it does cause damage to my rig, I am the guy that will stand up and accept the responsibility and consequences of my actions.
