What You May Also Need
Usually required
- Type BR branch breakers sized for each circuit (for example BR220 / BR240 family).
- Upstream overcurrent protection and feeders sized for a 125 A main-lug panel.
May be required
- Neutral and ground kits as required by the installation instructions and local code.
- Disconnects & Breakers: Outdoor disconnects ahead of or beside the panel.
Optional upgrades
- Enclosures, Electrical & Safety: Related electrical balance-of-system hardware.
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Main-lug panels do not include a factory main breaker. Provide protection upstream as required.
- NEMA 3R is rainproof — keep openings and knockouts sealed per Eaton instructions and the NEC.
- Use only breakers listed for Type BR loadcenters.
- Professional installation required.
