Sub Panel Installation
Extend your service safely with a properly sized, properly grounded sub panel — installed to code.
About Sub Panel Installation
When the main panel is full or the new load is far from the house, a sub panel is the right answer. J&R Electric installs sub panels across Southern California for garages, workshops, ADUs, additions, pool equipment, and EV chargers — properly sized feeders, isolated neutrals, and grounding bars done correctly.
When You May Need This Service
If any of the following sound familiar, it's time to call a licensed electrician.
- Main panel is full — no breaker slots left
- Building or finishing a garage, ADU, or workshop
- Adding pool, spa, or shop equipment
- EV charger plus other new loads
Why It Matters
Properly performed sub panel installation work protects your safety, keeps your home or business up to current California electrical code, and preserves the long-term value of your property. Cutting corners on electrical work can lead to fire risk, failed insurance inspections, voided warranties, and expensive rework down the line.
- Add capacity without replacing the main panel
- Dedicated breakers near the load
- Cleaner organization of large additions
- Required for many ADU and garage conversions
