Considerations for Selection

• Rated Current: Level 3 boxes should match the outgoing current of Level 2 boxes (e.g., 63A or 100A main switch) to ensure proper load handling .
• Sockets and Terminals: Choose boxes with appropriate industrial sockets (4-core or 5-core) depending on equipment requirements.
• Environmental Protection: Look for IP ratings (IP65–IP69) and NEMA 3R or equivalent for outdoor use.
• Customization: Some manufacturers offer pre-wired or modular designs for easier installation and maintenance.
• Compliance: Ensure boxes meet relevant standards such as EN IEC 61439, UL 1640, or cULus listings for safety and reliability . These manufacturers provide reliable solutions for temporary power distribution on construction sites, with options for both Level 2 and Level 3 distribution boxes tailored to specific site requirements.
