Size of wire and breaker

I am installing a couple of 60watt lights and a sprinkler control box and a small water feature pump. i will have a run of about 325 feet. what size of wire and what size of breaker for the main run to a small sub panel with 3 breakers of 15 amps for the lights, sprinkler and fountain pump?

Doesn't seem like this would draw much so three 15A circuits sounds like overkill. Do you know power draw of fountain pump? Sprinkler controller is probably less than 25W.

I think a single 14-2 UF cable fed by a single 15A breaker with a GFCI receptacle instead of a breaker panel at the remote point then slave the lights, pump, and sprinklers off of the load side of the GFCI. You get a 120VAC outlet as an extra bonus.

If I'm digging 325', I'm installing conduit, and leaving provisions for the future, without seeing what you are actually doing, I might pull #6AWG, to a remote panel...

Go big or go home lol. Probably need a number 6 anyways at that distance. Taking a random number of 8a you would need a number 8 wire to get it out there.

I'm here to learn too, i do mostly commercial/industrial/new construction and this place is a great way to pick up tips on residential from some good electrical minds. Excuse the spelling, my phone has a mind of it's own.
