You can have a 30 amp breaker contained by the house and run it to the shed. But then you hold to split the line contained by the shed to 15 or 20 amps to use it for anything. A 30 amp is for a electrical water kiln or something else big like that,,which idoubt you enjoy in a shed.
Why not a moment ago run 2 lines to the shed,,,say 2 15 ampers.In the shed you in recent times put in 2 gfi outlets,,,one for respectively line??
