A well-placed subpanel brings circuits closer to where the power is used and keeps your main panel organized and manageable.
Overview
What a subpanel does
A subpanel is a secondary distribution point fed from the main panel. Instead of running many long individual circuits back to the main service, a single feeder supplies the subpanel and the branch circuits are distributed locally. That usually means shorter runs, clearer organization, and easier future changes.
Whether a subpanel is the right answer depends on your existing service capacity, the distance involved, the loads you plan to add, and the construction of the building. Some homes benefit greatly; others are better served by different work. That determination is made during an on-site assessment.
Safety first
Subpanels require correct grounding and separation of grounded and grounding conductors. Incorrect subpanel wiring is a common and hazardous DIY mistake, and it is not always visible from the outside.
Spaces a subpanel can support
- Detached or attached garages
- Workshops and hobby spaces with tools and equipment
- Home additions and converted spaces
- Accessory dwelling units (ADUs)
- Additional circuits when the main panel is full
- More organized power distribution across the property
The process
How subpanel work generally proceeds
- 01
Assess capacity
We look at your existing service and main panel to understand what is available to feed a subpanel.
- 02
Plan the feeder
Routing, distance, conductor sizing, and protection are evaluated for the specific installation.
- 03
Set the location
The subpanel is placed for practical access, clearance, and proximity to the circuits it will serve.
- 04
Install and terminate
The feeder and subpanel are installed with correct grounding and neutral separation.
- 05
Circuit build-out and labeling
Branch circuits are added, tested, and clearly labeled at the subpanel.
