Need help with panel wiring
I have a panel in an shed. The panel is the shed is wired to a 30 amp double pole breaker at the main house panel. They put a 60 amp breaker in the panel in the shed and are using one leg of that breaker to supply 120 V for the lights and outlets.
I want this done properly so can I remove that 60 amp breaker and use 2 15 amp breakers in it's place? Remember the panel is connected to a 30 amp breaker at the main house panel. I have no idea why the used a 60 amp single breaker in the shed panel.
Below is a picture of the shed panel.
Thanks

The breaker in the shed needs to be sized to the wire size used for the circuit. If the wire is #14 then you do need to change to a 15A in the shed. But to answer your question directly the dp60 can be replaced with 2 single pole 15A. Also a ground bar needs to be added and the neutral isolated from the ground. Plus ground rods should be added. A clamp is needed on the romex at the box entry. Is the feeder wire to the shed regular romex and is it underground?

It does have a ground bar in it although very small places for 2 wires. The cable is underground in a PVC pipe going to the main breaker box where it is tied into a 30 amp double pole breaker. The wire is 12 gauge that currently runs 6 outlets and 2 lights.
Just to be clear the box pictured above is what is in the shed.
Could another option be to replace that breaker pictured above with a 20 amp double pole breaker and run 2 circuits one off each pole of the 20 amp double pole?

The white neutral should be connected to a separate bar from where the bare ground wire is connected. The neutral bar needs to be insulated from the box. If the circuit wire is #12 the protecting breaker can be a 20A, either using a single or double pole. If the feeder from the house is white romex in conduit underground that is not appropriate. The only romex allowed underground is type UF.
