Leviton 30 Amp 480V 3-Phase Locking Plug (L16-30P)
The Leviton L16-30P locking plug is designed for 30A at 480V three-phase systems. It features a black-white color scheme for grounding clarity and industrial-grade construction. One-piece contacts reduce friction and overheating, supporting reliable performance under heavy use. Best for field electricians and workshop setups requiring secure, twist-lock connections. A potential limitation is that compatibility depends on the matching L16-30R receptacle and the correct cord size.
IronBox Electric NEMA L16-30 Plug – 30A 480V
The IronBox L16-30P male twist-lock plug delivers 30A at 480V with heavy-duty construction for commercial and industrial environments. It’s well-suited for servers, data centers, generators, and PDUs requiring stable connections. Best for users who need a robust, secure twist-lock option and compatible with L16-30R configurations. Limitation: data sheets emphasize compatibility with standard 30A twist-lock receptacles; verify your receptacle configuration before purchase.
Yinony L16-30R Industrial Locking Receptacle
The Yinony L16-30R female locking connector offers an industrial-grade nylon housing with high-temperature resistance and brass contacts for reliable conductivity. It’s designed for generators, transfer switches, welding gear, RVs, and other 480V 3-phase setups. Choose this if you need a rugged receptacle with a wide clamp for various wire sizes. Caution: ensure correct polarity and matching L16-30P plug to prevent mis-mating.
Power Assemblies Camlock Connection Box
This 800A, 3-phase, 4-wire NEMA 4/12 distribution box includes Camlock outputs and multiple color options for signaling. It’s a strong choice for centralized power distribution in industrial settings and generator backfeeds. Best for job sites needing a durable, weather-resistant box. Limitation: larger footprint means more space is required in the installation area, and it may be overkill for small setups.
Electrineering 50A 480V SOOW Power Cord
The 50A 480V SOOW power cord provides a three-pole, four-wire setup with a locking plug and connector. It’s ideal for heavy equipment, welders, HVAC systems, and temporary power on job sites. Best for longer run needs and high-current equipment. Caution: ensure the cord length is appropriate to minimize voltage drop and risk of damage in dynamic environments.
Buying Guide: Key Considerations For 480V 3-Phase Accessories
- Voltage and current ratings: Confirm that the product rating matches your generator output and load requirements (e.g., 30A, 480V, 3-phase).
- Locking mechanism: Choose locking plugs/receptacles to prevent accidental disconnections in vibrating or outdoor environments.
- Durability and materials: Look for heavy-duty plastics or nylon housings, brass contacts, and reinforced construction for industrial use.
- Compatibility: Ensure plug-to-receptacle compatibility (L16-30P vs L16-30R) and alignment with your distribution hardware.
- Temperature and environment: Consider high-temperature ratings and weather resistance for outdoor or harsh-site conditions.
- Cable management: For cords, check length, flexibility, and the ability to handle continuous loading without overheating.
- Footprint and space: Camlock boxes and large distribution units require adequate installation space and proper mounting.
- Safety considerations: Use proper grounding and color-coded components to minimize miswiring risks.
Frequently Asked Questions
- What is the difference between L16-30P and L16-30R?
– L16-30P is the male locking plug, while L16-30R is the female receptacle. They mate together for a secure connection in 480V 3-phase systems. - Is a 50A cord suitable for all 480V 3-phase generators?
– It depends on the load and distance. A 50A cord is appropriate for high-current equipment but verify voltage drop and connector compatibility. - Can I mix brands for L16-30P and L16-30R?
– It’s best to match brands for reliable locking and electrical contact integrity; mixing can risk incompatibility or poor fit. - What should I consider when selecting a camlock distribution box?
– Look at amperage rating, NEMA compatibility, weatherproofing, and the number of outputs to fit your setup. - Are these accessories suitable for temporary outdoor power?
– Yes, many are designed for outdoor industrial use, but confirm IP rating and weather resistance for your environment. - Do these items affect generator warranty?
– Using compliant, correctly rated components typically preserves warranty terms; consult your generator manual if unsure.
