- Enclosure rating and weather resistance: Look for IP or NEMA ratings appropriate for your climate (NEMA 3R, IP65 are common choices for outdoor use).
- Main breaker and space: Confirm a true 200A main and adequate spaces for future expansion; count the available slots and intended feeder circuits.
- Compatibility: Ensure the enclosure supports the preferred breaker brands and types (Homeline, QO, QOM, etc.) and that plug-in or bolt-on options meet your installation needs.
- Wiring accessibility: Consider designs with clean wire management, knockouts, and easy rough-in or surface-mount options for a tidy, safe installation.
- Durability and materials: Galvanized steel and corrosion-resistant finishes extend service life in outdoor environments.
- Installation kit included: Some models ship with main breakers and a set of branch breakers, which can reduce install time and costs.
- Code compliance: Verify that the chosen model complies with local electrical codes and utility requirements for service entrances.
- Maintenance and serviceability: Favor enclosures that provide straightforward access, labeling, and compatibility with common replacement parts.
