Whether you’re transforming your garage into a workshop, gym, EV charging station, or just need better lighting and power, professional garage electrical wiring is a must. It’s not just about convenience—it’s about safety, performance, and future-proofing your property.
In this guide, we’ll cover everything you need to know about garage wiring installation, including circuits, lighting, outlets, and how to ensure everything is done up to code.
Why Garage Electrical Wiring Matters
Your garage likely started with minimal power—maybe a single light and outlet. Today’s garages need to handle far more: tools, appliances, EV chargers, freezers, smart openers, and even HVAC.
Benefits of Upgrading Garage Electrical Wiring:
-
⚡ Dedicated circuits for tools, chargers, or HVAC
-
🔌 Safe and convenient outlet installation in garage
-
💡 Proper garage lighting wiring for visibility and security
-
🛠️ Capacity to add power tools or EV charging stations
-
📋 Ensures code-compliant garage wiring for safety and insurance
Whether you’re a DIYer or just tired of extension cords, a professional setup delivers peace of mind.
Planning Your Garage Wiring Installation
Before beginning your garage wiring installation, it’s important to determine:
-
🔹 Power needs – What appliances and tools will you be running?
-
🔹 Future use – Do you plan to add an EV charger, air compressor, or heater?
-
🔹 Panel location – Is your garage electrical panel inside or outside the garage?
-
🔹 Lighting preferences – Ambient vs. task lighting
-
🔹 Code requirements – NEC and local building codes
A licensed electrician can perform a load calculation and provide tailored circuit planning.
Garage Electrical Panel & Circuits
If your garage is detached or far from your main panel, you may need a subpanel installed.
Garage Electrical Panel Setup:
-
Subpanel (if needed): 60–100 amps
-
Breaker Types: AFCI/GFCI dual-function breakers
-
Conduit: EMT or PVC for exposed runs
-
Wiring: THWN or NM cable depending on installation type
-
Grounding: Ground rod and bonding where required
Garage Circuit Installation Options:
-
20A general-use circuits – For outlets and lights
-
30A or 50A circuits – For heavy-duty tools, heaters, or EV chargers
-
Dedicated circuits – For freezers, air compressors, or welders
-
GFCI protection – Required for all 120V outlets
Every garage circuit installation must meet NEC 2023 code updates, including tamper-resistant and GFCI outlets.
Garage Lighting Wiring
Poor lighting is one of the biggest frustrations in garages. A solid garage lighting wiring setup improves visibility, security, and functionality.
Lighting Types to Consider:
-
LED overhead lights – Bright, energy-efficient, and long-lasting
-
Task lighting – For workbenches or tool areas
-
Motion-activated fixtures – For hands-free entry and safety
-
Exterior garage lights – Add security and curb appeal
Use 15A or 20A lighting circuits with switches placed at entry points for convenience.
Outlet Installation in Garage: Best Practices
Strategically placed outlets eliminate the need for extension cords and support all your garage tools and gadgets.
Garage Outlet Placement Tips:
-
One outlet every 6 feet along walls
-
GFCI outlets at all accessible points
-
Ceiling-mounted outlets for garage door openers or reels
-
Exterior-rated outlets for outdoor tool use
-
Dedicated outlets for refrigerators or freezers
All outlet installation in garage should include in-use covers and be mounted 18″ above floor level to meet code.
Detached Garage Wiring Considerations
Wiring a detached garage often requires trenching and additional safety steps.
Detached Garage Wiring Includes:
-
Underground conduit (18″ deep minimum)
-
A subpanel for local circuit control
-
Grounding and bonding
-
GFCI-protected circuits
-
Possible garage electrical panel upgrades
Running new power to a detached structure must comply with NEC and local permit guidelines—leave it to a licensed electrician.
Why Hire a Licensed Electrician
Garage wiring involves amperage calculations, GFCI/AFCI compliance, and detailed code knowledge.
Benefits of Hiring a Pro:
-
✅ Proper sizing of circuits and wire
-
⚙️ Safe breaker and subpanel configuration
-
🧯 Code-compliant installations that pass inspection
-
🧰 Clean, professional-grade wiring with labeling
