Wiring a shed can seem like an intimidating task, but with some planning and basic electrical knowledge, you can safely wire your shed without hiring an electrician for less than $50. In this guide, I'll walk you through the entire process step-by-step, from assessing your electrical needs to picking the right materials and wiring everything up to code. With the help of this guide, you'll be able to bring power to your shed while saving hundreds of dollars in electrician fees.

Assess Your Electrical Needs

The first step is to determine what kind of power you need in your shed and how much of it you'll require. Here are some key factors to consider:


Decide how many light fixtures and outlets you need. More powerful lights like floodlights will require more wattage.


Determine how many outlets you need and the amperage required, like for power tools.


Consider any larger appliances like a refrigerator or space heater and their electrical demands.

Circuit Breaker

Choose an appropriate circuit breaker size like 15 or 20 amps based on your total electrical load.

By calculating your lighting, outlets, and appliance needs, you can properly size your electrical system. It's better to overestimate your needs slightly.

Choose the Right Materials

You'll need some basic materials for shedding wiring:

Tools like wire strippers, a voltage tester, and safety gear are also essential. You may also need additional supplies like junction boxes, wire connectors, and mounting hardware.

Shopping around can help you get quality materials at the best prices. Buying wire and breaker boxes in bulk saves a lot.

Running the Wire to the Shed

With your materials purchased, you can start the wiring process:

Step 1: Turn Off Power

Turn off power at the main breaker before doing any work. Verify it's off with a voltage tester.

Step 2: Run Conduit to Shed

Trench conduit 18-24 inches deep from the house to the shed. Use smooth sweeps and long radii.

Step 3: Fish Wire Through Conduit

Carefully pull the electrical wire through the conduit leaving some extra wire on both ends.

Step 4: Install GFCI Breaker

Install a GFCI breaker in the main service panel sized for your electrical load.

Installing Receptacles and Lights

Next, you can add receptacles, switches, and lighting inside your shed:

Step 1: Mount Outlet Boxes

Securely mount weatherproof outdoor outlet boxes where needed.

Step 2: Connect Wires

Connect the wires to outlets and light fixtures using proper connectors. Follow diagrams.

Step 3: Install Lights

Mount any lights and connect wires to them as well. Follow all housing instructions.

Step 4: Attach Faceplates

Attach weatherproof faceplates to all outlets and light fixtures. Caulk any openings.

Wrapping Up the Installation

You're almost done with the hard work at this point:

Step 1: Secure Wires

Use insulated staples to securely fasten all wires inside the shed every 18-24 inches.

Step 2: Label Breakers

Properly label the new breaker controlling the shed circuit.

Step 3: Test Circuit

Turn power back on and carefully test all lights, outlets, and controls. Verify proper function.

Safety First! Follow all local codes and permit requirements. Bury wire at proper depths. Take precautions against shock and electrocution.
