If you have an outdoor shed that you wish to power for lights and electrical sockets, all that is required is a small amount of wiring knowledge and some basic components. The best way to get power to an outdoor shed is to run wiring underground. This protects the electrical feed from being knicked or cut by lawn equipment and keeps it from being a tripping hazard. The whole project should not take more than a day to complete.
Dig a trench to run the wiring and conduit from the home's main electrical panel to the outdoor shed. If possible, dig underneath the shed enough to run the wiring up through the floor.
Shut the main electrical panel off by switching off the main circuit breaker. Install a 60 amp breaker into the main electrical panel to power 20 amp breakers and outlets in the shed. Wire a 6 gauge electrical to the newly installed 60 amp breaker and feed the 6 gauge wire into PVC conduit. Once the 6 gauge wire is run through the PVC conduit, run the other end into the shed. Go up through the floor if possible. Drill a hole and pull the wiring up through it.
Mount a mini electrical panel in the shed. Fasten it to a wall with screws or bolts using a screw gun. Install 20 amp breakers into the empty mini electrical panel to provide power to various lights and outlets. Mount outlets and lights where needed in the shed with screws. Run 14/3 wiring from the mini panel to any light receptacles and 12/3 wiring to any outlets.
Test the outlets and lights. Turn the power back on at the main electrical panel. Turn on the lights and plug in a radio or small hand tool such as a sander or circular saw into the outlets to see if power is running to each light and outlet. Bury the PVC conduit by filling the trench.
