Power Assemblies 800 Amp CAM Lock Panel — 3 Phase 120/208V
- Voltage/Phase: 120/208V, 3 Phase
- Position Count: 8
- Features: CAM Panels are shipped pre-assembled; NEMA 3R Caps and Lanyards; Series 16 CAM Connectors
This option is best for facilities needing a compact 800A panel at 120/208V. It suits light industrial applications, temporary installations, and event power where quick setup matters. Consider this when space is limited and you require faster installation compared to field‑fabricated panels. A potential limitation is its focus on 120/208V; if 277/480V is needed, choose a different configuration.
Power Assemblies 10 Position CAM Lock Panel — 277/480V
- Voltage/Phase: 277/480V, 3 Phase
- Position Count: 10
- Features: Pre-assembled CAM Panels; high density; standard configurations for temporary power
Best for mixed-voltage applications where 277/480V is standard, such as certain commercial and industrial systems. It reduces on-site labor with pre-assembled panels. If you only require 120/208V, this might be more than needed, but it handles higher voltage responsibly and neatly.
Power Assemblies 10 Position CAM Lock Panel — 120/208V, Female
- Voltage/Phase: 120/208V, 3 Phase
- Position Count: 10
- Features: Pre-assembled panels; high-density connections; standard configurations
Choose this when the distribution needs to feed 120/208V loads with female terminations. It’s suitable for data centers, office spaces, or lightweight manufacturing lines. Note that 277/480V compatibility is not included in this unit; plan accordingly if higher voltage is required.
Power Assemblies 8 Position CAM Lock Panel — 208V
- Voltage/Phase: 208V, 3 Phase
- Position Count: 8
- Features: Pre-assembled CAM Panels; high density; standard configurations
Best for compact 208V distribution in spaces where multiple branch circuits are needed without sacrificing ease of installation. It provides a balance between size and capacity. If you require higher voltage or more positions, review the 10‑position models above.
Power Assemblies 10 Position CAM Lock Panel — 277/480V, Female
- Voltage/Phase: 277/480V, 3 Phase
- Position Count: 10
- Features: Pre-assembled panels; efficient layout; standard configurations
Designed for higher voltage distribution with female terminations. It’s well-suited for facilities that routinely run 277/480V equipment. If your system mainly uses 120/208V, this unit may be less cost-efficient than 120/208V options.
Buying Guide
- Panel voltage and phase: Choose a panel that matches your facility’s nominal voltage (e.g., 120/208V, 277/480V). Misalignment can require adapters or upgrades.
- Position count: Determine how many separate circuits you need. More positions provide future expansion but may increase footprint and cost.
- Pre-assembled vs field assembly: Pre-assembled CAM panels save labor time but ensure your layout matches the standard configurations offered.
- Durability and enclosure rating: NEMA 3R/4/12 ratings indicate suitability for outdoor or harsh indoor environments. Select a model that matches your environment.
- Installation footprint: Consider space constraints. Higher-density panels help in tight spaces but may have more complex wiring layouts.
- Accessories: Check for caps, lanyards, and CAM connectors compatibility, and ensure redundancy options are available if uptime is critical.
Practical considerations
- Wiring simplicity: Pre-assembled panels reduce field machining. If you must cut holes, anticipate higher labor and potential delays.
- Maintenance access: Choose a layout that allows easy access to circuit breakers, CAM connectors, and terminations for routine maintenance.
- Future expansion: Favor configurations with spare positions or modular add-ons to minimize replacement costs later.
- Safety compliance: Verify enclosure ratings and shielding meet regional electrical codes and site safety policies.
FAQ
- Q: What is the main advantage of CAM lock panels for 800A systems? A: They provide rapid, bolted connections with pre-assembled configurations that reduce field labor and ensure reliable, repeatable layouts.
- Q: Which voltage is most common for 800A CAM panels? A: 120/208V and 277/480V are common, depending on the facility’s loads and equipment; choose based on your feeders.
- Q: Can I mix voltages in one panel? A: Typically not within a single module; use separate panels or a configurable system designed for mixed voltages if needed.
- Q: Are these panels suitable for outdoor use? A: Many are rated for indoor/outdoor use (NEMA 3R/4/12 options). Confirm the enclosure rating for your site conditions.
- Q: Do these products require special installation tools? A: Pre-assembled CAM panels simplify installation, but ensure you have basic electrical PPE and standard hand tools for mounting and wiring.
- Q: What is a good rule of thumb for number of positions? A: Plan for your current circuit count plus several spare positions for future expansions whenever possible.
