This 5-position CAM Lock Panel is rated at 400A, 3-phase, 120/208V with female, 45° post connections and Series 16 CAM connectors. Panels are shipped pre-assembled, reducing on-site labor and cutting the need to punch holes for panel-mounted CAMs. The high-density configuration supports more connections per square foot, and the unit uses NEMA 3R caps with lanyards for secure field use and weather protection. It is compatible with many temporary power setups and can simplify complex power layouts.
Power Assemblies 5 Position CAM Lock Panel – Female, 90°
This 5-position CAM Lock Panel in a 90° female orientation provides pre-assembled, ready-to-install configurations for 400A, 3-phase, 120/208V applications. The Series 16 CAM connectors support dense layouts while preserving ease of access for maintenance. The panel emphasizes high-density designs and standard configurations suitable for most temporary power needs in commercial environments.
Power Assemblies 5 Position CAM Lock Panel – Male, 90°
This 5-position, 400A, 3-phase CAM Lock Panel features male 90° connections with double set-screw terminals and NEMA 3R clear snap-back covers. The pre-assembled packaging minimizes field labor and wiring complexity, while the high-density design increases the number of CAM connections per square foot. It remains compatible with Series 16 devices and supports a range of temporary power applications, making it a practical option for quick, scalable setups.
Buying Guide: Key Considerations for 400 Amp 120/208 Panels
- Voltage and phase compatibility: Confirm 120/208V, three-phase operation for your site’s electrical system. Some panels include single-phase options; ensure the model matches your distribution needs.
- Enclosure rating and environment: NEMA 3R or NEMA 4/12 ratings indicate weather resistance and durability. Choose based on indoor vs. outdoor deployment and exposure to dust or moisture.
- CAM Lock compatibility: Series 16 CAM connectors are common for rapid assembly. Verify connector compatibility with any existing gear from other brands if intermixing components.
- Pre-assembly vs. field assembly: Pre-assembled panels save labor and reduce installation time, but confirm if any customization is required for your application.
- Mounting orientation: Panels can be configured for 45° or 90° post connections. Select orientation that best fits your available space and cable routing.
- Safety and labeling: Ensure clear labeling, appropriate lockout/tagout provisions, and protective caps to prevent accidental contact with live terminals.
- Expandability: Consider high-density layouts and future expansion needs. A design with higher connection density can simplify scaling as demand grows.
- Maintenance access: Plan for easy access to CAM connectors and terminals for testing, servicing, and future reconfiguration.
- Interoperability: If combining devices from multiple brands, verify mechanical and electrical compatibility to avoid fitment issues.
