I do like the ideas for the additional 30amp power cord. Didn't think of that and it makes sense to do that instead of the 12 or 10 gauge cord.
Yes, you'll simply swap out the 40 amp breaker for a 30 and use the available space in the box to feed your outlet. Depending on where the 40 amp pool circuit ran to, you might be able to utilize that wiring to feed your outlet box as well.

EDIT: Just be sure your 30 amp outlet gets wired to 110v!!
Many get into trouble when they mistakenly wire it at 220v like some older home, 30 amp dryer/range outlets were.

There are a lot of options when running a dedicated circuit.

Here is what I did on the outside of my outbuilding. I actually have the box on an 80 amp circuit, so I can load all three receptacles at the same time (if I needed).

I can't run my air conditioner on my garage 20 amp circuit. Do you have 30 amp available?

Odd, I can run my AC on the 15 amp circuit, nothing else, but the AC will run.

Could be that the garage circuit is on a GCFI and the 15 amp isn't. The RV doesn't like to have another GCFI ahead of it.

No matter what size cord or wire you use if you have to use an adapter they are only rated to 15 amps. For anything over that you have to match the 30 amp plug on the rv.

We had an electrician put a 50A in (for "someday" when we get an A) when we had our breaker box upgraded. Be sure to ask for or install a breaker switch near the outlet - we have to go inside to the basement to flip it on or off. As others mentioned, make sure to not wire it like a clothes dryer!!

I used a 10g (might've been 8? It was thick and heavy), 100' cord before this was installed, but never ran more than the fridge and maybe the tv. Good luck :-)

I use 10 gauge wire from the house to the trailer. The voltage drop was too great with even a 12 gauge wire to safely run the AC without causing issue due to low voltage (brown out situation). With the AC on I am drawing about 13 amps on a standard 15 amp circuit with proper voltage with the 10 amp. I spent the money on the heavier wire under the premise better safe than sorry.

Recently, I have been doing some mods on our camper. I sometimes run the AC especially with the 90 plus degree days around my place. I haven't installed a 30 amp plug yet but plan on it soon. I am running a 10ga ext cord with the 15 amp adaptor. I only run the AC. I use flashlights if needed.

While doing a remodel in basement a few years back, it worked out we ran a dedicated 15 amp outlet. So I use that one only with that ext cord. The heat gun never has shown an increase in heat at either cord end. And the volt meter shows 119v when compressor is off and when it kicks on, the volts drop to 117v.

I probably have 6 or 7 more days where I'll be needing to do this. at the most, it is 5 to 6 hours at a time. When finished, I can start the process of adding a 30 amp box. Would this be relatively safe to continue this. Or should I just skip the work and add the outlet?

Thanks for the replies.
