10 amp overcurrent protective device if it is 90C. You need to increase the wire size and then reduce the number of conductors or use 2 runs of conduitThey say I shot a man named Gray and took his wife to Italy
She inherited a million bucks and when she died it came to me

In a dry location starting ampacity of #12 is 30 amps.
In a wet location starting ampacity of #12 is 25 amps.
I came up with 10 amps  dry / 5 amps wet.
