Having a garden shed is great for storage and workspace. However, in order to make full use of the shed, you'll likely want to wire it up with electricity. The good news is that wiring a shed is totally doable even if you have no prior electrical experience. With some planning, safe practices, and helpful tips, you can successfully wire up your shed in no time.

Gather the Required Materials

Before starting any electrical project, you'll need to gather the required materials. Here's what you'll need to wire a basic garden shed:

Having all of these materials ready will make the installation process go faster and smoother.

Run Power from the Main Panel

The first step is getting power from your main electrical panel out to the shed. Here are two options for running the power cable:


For an underground run, bury 12/2 direct burial rated cable at least 18 inches deep. Run it through PVC conduit under any walkways or driveways to protect the cable. Use waterproof conduit fittings.


For an overhead run, use cable rated for outdoor use such as NM wire and securely fasten it with cable staples. Keep it high enough to avoid contact with people and equipment passing underneath. Use conduit for any places the cable crosses over walkways.

Important Safety Tip

Make sure the power is shut off at the main panel before doing any work!

Install a Subpanel in the Shed

Once the power cable is run to the shed, you'll need to install a subpanel to distribute and control power in the shed:

Having a subpanel with multiple breakers allows you to protect each circuit in the shed separately.

Run Circuits and Outlets

Next you can start running cable and installing electrical boxes for lights, outlets and switches:

Key Takeaway

Labeling the wires makes it way easier to keep track of what gets connected together, especially when you're new to wiring!

Install Lighting

Proper lighting is key for any functioning workshop or storage space. Here are some tips for lighting your shed:

Proper lighting will make working in the shed much easier and safer. Plus it just makes the space more inviting!

Incorporate GFCI Protection

Any outdoor receptacles or outlets in a damp location must be GFCI protected for safety. Here are a few options for adding GFCI protection in a shed:

GFCI protection is an important safety requirement that prevents electrocution and shock hazards.

Do a Final Check and Power Up!

You're almost ready to start using your wired up shed! Follow these final steps first:

Take the time to check your work - this is crucial to avoid safety issues or fires once the power is live!


Now you can plug in, turn on, and enjoy your newly electrified, properly wired garden shed! Just follow basic electrical safety and your shed wiring should provide many years of trouble free use.
