Power Assemblies 5 Position CAM Lock Panel (400A, 3P, 120/208V)
This 5-position CAM Lock Panel provides 400A capacity at 3-phase 120/208V with female connectors at a 90-degree orientation and double set-screw connections. It ships pre-assembled with NEMA 3R caps and lanyards for added protection during outdoor or semi-open installations, while Series 16 compatibility ensures broad device interoperability for temporary power applications.
Buying Guide: Key Considerations for Cam Lock Power Distribution Panels
- Amperage and voltage: Match the panel rating (e.g., 400A, 800A; 120/208V, 277/480V) to your load requirements and electrical code compliance. Higher amperage generally supports more devices but requires appropriate wiring and protection.
- Enclosure rating: NEMA 4/12 and similar ratings protect against dust, water, and weather exposure. Choose based on installation environment—indoor, outdoor, or wet locations.
- Phase and wire configuration: Verify 3-phase, 4-wire setups align with your distribution plan. Some panels offer single-phase options or configurable inputs for versatile use.
- Connector type and count: Series 16 CAM connectors provide standardized interfaces. Consider the number of male/female sockets and whether color-coding supports quick identification and safer operation.
- Mounting and installation: Pre-assembled panels reduce on-site labor. Evaluate mounting options (wall-mount, free-standing) and whether set screws provide secure terminal connections in vibration-prone environments.
- Durability and materials: Copper conductors with robust plastics or metal housings extend life under harsh conditions. Assess environmental exposure, temperature ranges, and maintenance expectations.
- Compatibility and expandability: Check if the panel is compatible with other brands’ Series 16 devices when future expansion is needed. Universal compatibility can simplify upgrades.
- Color-coding and safety: Color options for different phases or circuits help prevent miswiring. Ensure labeling and caps protect live connections when not in use.
