Modular Custom Circuit Layout, Flexible Matching Multiple Loads
Support customized one-level, two-level and three-level distribution schemes. We can freely configure watt-hour meters, industrial plugs, air switches and branch circuits according to customer's construction equipment power demand. The internal busbar adopts color-coded copper bars (yellow-green-red-blue) for clear wiring, convenient for later inspection and maintenance.
Detachable Mobile Bracket Design, Easy On-site Transfer
Medium and small distribution boxes are equipped with foldable integrated metal stand, which can be directly placed on the construction ground without additional support. The lightweight cabinet design allows 1 worker to move it alone, greatly improving the turnover efficiency of temporary power supply for multi-stage construction projects.
Complete Standard Accessories, One-stop Delivery Without Secondary Assembly
All internal electrical components adopt well-known domestic brand breakers with stable quality. The box is pre-wired and fully tested in factory before delivery. Matching door lock, grounding copper bar, wiring terminal and rain cover are all equipped, customers only need to connect incoming and outgoing cables on site to put into use, saving construction preparation time.

| FAQ |
Q: Can this distribution box work in rainy open-air construction sites?
A: Yes. The sloped waterproof top and full rubber door sealing strips reach IP33 protection grade to prevent rainwater infiltration. We can add extra external rain covers for long-term outdoor open-air use to strengthen waterproof performance.
Q: Is the internal circuit layout customizable according to my equipment?
A: Full customization is supported. We can configure the quantity of main switches, branch circuits, industrial sockets and watt-hour meters according to your welding machines, cutting tools and lighting load, and provide free wiring layout drawing.
Q: What's the difference between Level 1, Level 2 and Level 3 distribution boxes?
A: Level 1 box is the main incoming power cabinet for overall power control; Level 2 is sub-distribution cabinet for large machinery; Level 3 is terminal portable box for hand-held small tools. We can supply matching sets of three-level boxes for complete construction power systems.
Q: Are the circuit breakers inside the cabinet replaceable?
A: All breakers adopt standard general specifications, easy to purchase replacement parts globally. The modular rail installation design allows quick disassembly and replacement without re-wiring.
