Electrical – How to add a 30 amp breaker for an RV connection

electrical

I am trying to determine the most cost effective way to add a 30 amp breaker so that I can plug in and run the air conditioner unit on my RV. Currently my panel is full and I don't have space to put in a whole new panel. I do have a 40 amp hot tub breaker box located outside but don't think I can add anything to it. So is it possible to just add another 30 amp breaker to a full panel and then wire a 10 gauge plug to it?

I like the idea of adding something to the hottub box if I could just wire a plug in right off of that box. This is a picture of the hottub box. It is a Beachcomber GFCI box. It looks like it has an open spot. I would just have to turn the hottub off to run the RV I assume

You're in luck -- your panel can accept another 240V breaker in the bottom knockout pair. You'll need a 30A Siemens type QP breaker to install there, which you can pick up at a typical big-box store. (A GFCI is not needed here, best I can tell, because this is a single outlet in dedicated service.)
