I have this box on the side of my house that powers my hottub. Hot Tub Electrical Box

Is it possible (without violating typical code) to add a 15 amp 110 breaker in this box with intention of powering a small (1/3 HP) sump pump.

The sump pump is not critical to keeping my home dry. I am just drying up a spot in my yard that is always a bit wet.

[EDIT] It is a 60amp breaker in the main panel feeding this box and there is a 60amp breaker in this box. It services a hot tub.

    Also, verify that there is actually a neutral in this box. If it's just a 240V load, they may have just run two hots and ground. It's not legal to use the ground as a neutral. Jul 1, 2017 at 14:02

It looks like there are 2 positions available to add new breakers. The panel will need to be opened to know for sure, also make sure to get the correct brand and type for that panel. I would make the first outlet a GFCI since it is outside and you would be good to go. The answer is yes it is possible within code.

    If that is indeed a mini-subpanel, you just nailed the answer. You just have to watch out, I've seen where those micro-panels have knockouts where they do not actually have slots. Jun 27, 2017 at 14:20
