400Amp Cam Lock Connectors
Single pole 400 Amp Cam Lock Connectors are a proven solution for generators, motors, load banks, stage entertainment, portable power and various industrial applications. Designed to be rugged and long lasting with superior conductivity. Easy to assemble with no special tools required. All of our Cam Lock Connectors will mate with other manufacturers of Cam style connector products.
Male and female sockets are now available in single stud and double set screw termination. Double set screw key benefits:
- Larger cables won't interfere with rows below
- Ideal for applications requiring versatile termination options.
3-Phase Electrical Color Codes (North America): 120/208/240V and 277/480V
3-Phase Electrical System Color Codes (North America)
Reference guide for conductor identification in 120/208/240V and 277/480V three-phase systems.
277/480 Volt 3-Phase System (High Voltage Industrial)
This color coding scheme is commonly used in industrial environments for higher-voltage systems to clearly differentiate phase conductors for safety and maintenance.
Phase & Ground Color Codes
- L1 (Line 1): Brown
- L2 (Line 2): Orange
- L3 (Line 3): Yellow
- N (Neutral): Gray
- PE (Protective Earth / Ground): Green or Green with Yellow Stripe
Note: This scheme is widely adopted in North America for 277/480V systems.
120/208/240 Volt 3-Phase System (Standard NEMA Colors)
Used in commercial and residential applications, this system follows the standard NEMA color codes.
Phase & Ground Color Codes
- L1 (Phase 1): Black
- L2 (Phase 2): Red
- L3 (Phase 3): Blue
- Neutral (N): White
- Protective Earth (PE) / Ground: Green or Green with Yellow Stripe
Standard Compliance: These colors align with common North American practices for low-voltage 3-phase systems.
