If you’re planning to upgrade your garage’s electrical system, a 60 amp sub panel is a smart and practical choice. It provides sufficient power to run multiple tools, overhead lighting, garage door openers, and even an electric vehicle (EV) charger. Plus, it offers a cost-effective solution without overloading your main electrical panel.
But before you install one, you need to consider the size, type, features, and installation process. This guide will walk you through everything you need to know to make an informed decision.
Understanding Sub Panels
What is a Sub Panel?
A sub panel is a smaller electrical panel connected to your main service panel. It acts as a branch panel to distribute power to a specific location, such as a garage or workshop. Instead of running multiple circuits from your main panel, a sub panel simplifies the wiring system and reduces electrical load on your main service panel.
Why Would You Need a Sub Panel in Your Garage?
A standard garage often needs more power than a single circuit can handle. Installing a 60 amp sub panel allows you to safely run multiple circuits for:
- Power tools (table saws, air compressors, welders)
- Lighting (overhead, task, and security lights)
- Garage door openers
- HVAC units (mini-split AC, heater)
- EV chargers
Is 60 Amps Enough for a Garage?
What Can You Run on a 60 Amp Sub Panel?
A 60 amp sub panel can comfortably handle the following: ✅ Power tools (table saws, drills, sanders, compressors) ✅ Overhead and task lighting ✅ Garage door openers ✅ Mini-split AC or heater ✅ EV charger (depending on power requirements)
Comparing 60 Amps vs. Other Panel Sizes
| Panel Size | Best For |
|---|---|
| 30 Amp | Basic lighting and small tools |
| 60 Amp | Moderate tool use, lighting, small HVAC systems |
| 100 Amp | Large workshops, heavy machinery, EV charging |
For most home garages, a 60 amp sub panel is the sweet spot between power capacity and affordability.
Key Factors to Consider When Choosing a 60 Amp Sub Panel
Panel Size and Number of Circuits
Choose a sub panel with at least 6-8 breaker spaces, ensuring you have enough room to add circuits for tools, lighting, and outlets.
Compatibility With Your Main Panel
Your main panel must support a 60 amp breaker and have enough space to accommodate the feeder wire.
Essential Features to Look For
✅ Surge Protection – Protects your tools from power surges
✅ GFCI Breakers – Prevents electrocution in damp areas
✅ Main Disconnect Switch – Allows power shut-off without touching the main panel
Step-by-Step Installation Guide
Tools and Materials Needed
️ 60 amp breaker (for the main panel)
️ Sub panel (with 6-8 spaces)
️ Feeder wire (#6 AWG copper or #4 aluminum)
️ Conduit, grounding rod, and clamps
Running the Feeder Wire
- Turn off power at the main panel.
- Run the correct gauge wire from the main panel to the garage.
- Use conduit for underground or exposed wiring.
Connecting the Sub Panel to the Main Panel
- Install the 60 amp breaker in the main panel.
- Connect the feeder wires to the main panel’s lugs.
- Secure the neutral and ground connections properly.
Wiring the Breakers and Grounding
- Install individual circuit breakers for tools, outlets, and lighting.
- Ground the panel using a grounding rod and copper wire.
Safety Precautions
⚠️ Always turn off power before working.
⚠️ Use insulated tools and wear gloves.
⚠️ If unsure, hire a licensed electrician!
Cost Breakdown for Installing a 60 Amp Sub Panel
DIY vs. Hiring an Electrician
- DIY Installation: $250-$500 (if experienced with electrical work)
- Professional Installation: $800-$2,500 (varies by location and complexity)
Estimated Costs of Materials and Labor
| Item | Estimated Cost |
| 60 Amp Sub Panel | $50-$150 |
| Feeder Wire | $100-$300 |
| Breakers | $10-$50 each |
| Labor (if hired) | $500-$1,500 |
Common Mistakes to Avoid When Installing a Sub Panel
❌ Using the wrong wire gauge (can cause overheating)
❌ Not grounding the sub panel properly
❌ Overloading circuits with too many tools
Conclusion
A 60 amp sub panel is the perfect power upgrade for your garage, providing ample capacity for tools, lighting, and even HVAC systems. By choosing the right size, features, and proper wiring, you can ensure a safe and efficient electrical setup. If unsure, always consult a licensed electrician!
