Whether it’s for a workshop, a cozy retreat, or a functional storage area, electrifying these spaces can significantly increase their utility and value.
In this guide, we’ll cover everything you need to know about adding electricity to these standalone structures—from assessing electrical needs and planning the installation to executing the work safely and in compliance with local codes.
All You Need to Know About Adding Electricity to an Outbuilding
Working With a Professional vs. DIY
While you might be tempted to DIY this project, you should avoid venturing out of your comfort zone.
It’s recommended that you hire a professional to ensure the electricity is installed safely, reliably, and up to code.
Assessing Your Space’s Electrical Requirements
Before anyone starts digging trenches or buying materials, it’s crucial to accurately assess the electrical requirements of your shed, barn, or freestanding addition.
Understanding your structure’s electrical demand is the first step in ensuring your project is functional and efficient.
1. Define the Purpose of the Building
What will you use the building for? Different activities require different amounts and types of power.
For example, a workshop with power tools will require more and more varied power supplies than a simple garden shed used for storing lawn equipment. List all the appliances, tools, and equipment you plan to use in the space.
Don’t forget about any additions or changes you might make, even if you’re not planning to add them anytime soon.
It’s more cost-effective to install a system that’s slightly more robust than currently needed than to overhaul the electrical system down the line.
2. List All Electrical Devices
Compile a detailed inventory of every item that will consume electricity, noting their wattage. This list may include:
Light fixtures
Heating units
Air conditioning systems
Computers, printers, and other office equipment
Power tools and machinery for workshops
Etc.
Based on this intended purpose and any other wishes you have for your new addition, your electrician will add up the voltage requirements and plan the best way to supply it.
Power Source Options for Your Outbuilding
Choosing the right power source is essential for ensuring the reliability and safety of your electrical system.
Each option has its benefits and limitations, and the best choice will depend on your specific circumstances, including location, usage patterns, and budget.
In most cases, consulting with a professional electrician can provide valuable insights into the most suitable and cost-effective approach for adding electricity to your outbuilding.
Here are the main options for powering your shed, barn, or freestanding addition, along with considerations for each:
Extending Existing Home Power
One of the most common methods is to extend the power from your existing home’s electrical system.
This involves running underground cables from your house’s main panel to the new structure. It’s cost-effective and straightforward, but the distance and the existing load capacity of your home’s electrical system determine its effectiveness.
Key Considerations:
Distance: The further your outbuilding is from the house, the more expensive and complex the installation will be, as it will require longer cable runs and potentially higher gauge wiring to handle the voltage drop.
Capacity: Ensure your current home system can handle the additional load without requiring a major upgrade.
Installing a New, Dedicated Circuit
Setting up a new, dedicated circuit from the main power pole might be a better option for buildings with substantial electrical needs or those located far from the main house. This can be more expensive due to the need for additional metering and potentially more complex installation, but it offers independent control and possibly improved reliability.
Key Considerations:
Regulatory Requirements: Often requires more extensive permits and inspections.
Cost: Generally higher initial costs due to the need for new metering equipment and possibly a new service drop.
Alternative Energy Sources
Solar panels or wind turbines can be viable options, especially for smaller loads or in areas with favorable conditions.
These can operate independently from the grid or be integrated with a traditional power source for hybrid setups.
Key Considerations:
Sustainability: Offers a green solution by reducing dependence on non-renewable energy sources.
Initial Investment vs. Long-Term Savings: Higher upfront costs might be offset by lower ongoing energy costs and potential subsidies or tax incentives.
The Installation
Proper installation of your electrical system is crucial for ensuring efficiency, safety, and long-term reliability.
The key phases your electrician will go through in the installation process are:
1. Trenching and Cable Laying
Your electrician will create a path for electrical cables that will run from your main power source to the outpost building. This involves:
Marking the Route: They will clearly mark the most direct route where the trench will be dug to minimize the length of the cable run.
Digging the Trench: The trench will be dug to a depth that meets local code requirements, typically at least 18 inches, to protect the cables from physical damage and environmental elements.
Laying Conduit: PVC conduit, known for its durability and ease of use, will be placed in the trench to house and protect the cables. All joints will be sealed properly to prevent moisture ingress.
Threading the Cable: The appropriate gauge of electrical cable, rated for underground use, will be run through the conduit.
Backfilling the Trench: Once the cables are laid and tested, the trench will be carefully backfilled to avoid any sharp rocks or debris that could damage the conduit or cables.
2. Setting Up the Electrical Panel
The electrical panel serves as the central hub of your building’s electrical system. Your electrician will:
Choose the Appropriate Location: Install the panel in a location that is easily accessible yet out of the way of regular activities, mounted at a height compliant with local codes.
Install Circuit Breakers: Your electrician will install appropriate circuit breakers in the panel. Each breaker is designed to correspond to a specific area or type of use within the building, enhancing safety by preventing overloads and short circuits. Make Connections: Connections from each circuit to the corresponding breaker and the main power line will ensure everything is properly integrated and secured.
Test the System: The entire system will be powered up, and each circuit will be tested to confirm that all components are functioning correctly.
3. Outlets and Lighting Fixtures
The practical elements of your electrical installation, such as outlets and lighting fixtures, will also be handled by your electrician:
Plan Placement: The placement of outlets and lights will be planned based on the layout and function of the building, ensuring convenience and adequate lighting.
Install Boxes: Junction boxes will be installed at each designated outlet and light fixture location to house wire connections securely.
Wire the Fixtures: Wires will be run from the electrical panel to each box, and all connections will be made according to detailed wiring diagrams.
Mount Fixtures: Outlets and light fixtures will be securely attached to their respective boxes. Options like LED fixtures may be chosen for their energy efficiency and adequate illumination.
Final Testing: A final comprehensive test will be conducted to ensure that every outlet and light operates correctly and safely.
Safety and Code Compliance
When adding electricity to any structure, ensuring safety and adhering to local building codes is crucial.
A professional electrician will handle these aspects efficiently, ensuring your installation is both safe and compliant:
Mastery of Local Electrical Codes
A professional will thoroughly understand the local electrical codes that govern installation practices and safety standards.
