I am going to run electric from my house to a shed I have in the back. I just want to make sure i'm doing this right. The shed is about 75 feet from the house. I am planning on running 10-3 underground wire from my main electric box. Using a dual 30 amp breaker. IN the shed i'll have another breaker box with 2 20 amp breakers (using 12-2 in the shed). one breaker for the lights and the other for the outlets. Does this sound correct? Or can I just not have the breaker box in the shed and connect the to circuits from the 12-2 to the 10-3 wire?
Thanks

At the shed, you need a disconnecting means for all energized conductors. The 2 breakers will serve the purpose, provided that the breaker box is marked as suitable for use as service equipment. At the shed, you will also need to drive two ground rods at least 6 feet apart and connect them to the neutral inside the breaker box ( based on 10-3 and no equipment ground).
If you want to skip the breakers, you could install a 2 pole 20 amp switch, reduce the breaker size at the house to a 2 pole 20. The switch does not need to be suitable for use as service equipment and, if you run 10-3 with ground, you can also eliminate the ground rods.
