A distribution board is the final node in a low-voltage distribution system, directly supplying, protecting, and controlling indoor lighting, socket, air-conditioning, and other small-power circuits. Typically wall-mounted in recessed or surface form, it integrates miniature circuit breakers (MCB), residual current devices (RCD), surge protective devices (SPD), and a copper busbar. Its core function is to split power arriving from the upstream panel into multiple final circuits, each with independent overload, short-circuit, and leakage protection. Cabinets use plastic or steel panels with transparent covers and dedicated label areas so an electrician can read switch status and identify every circuit at a glance. The design prioritizes miniaturization, aesthetics, and ease of operation, meeting mandatory building electrical design and acceptance requirements that protect against electrical fire and electric shock.
We run these terminal boards on a standardized high-volume line, so breaker wiring, torque, and circuit labeling come out the same on unit number one and unit number one thousand. Consistent rail-mounted component placement and a fixed wiring harness layout mean each 10 A lighting, 16–25 A socket-RCBO, and dedicated air-conditioning or water-heater circuit is dressed identically across the batch. For contractors and developers ordering hundreds of boards for one residential or hotel project, that production consistency cuts on-site commissioning time and eliminates wiring defects between units.

Applications
- Residential buildings. Each household board is the last safety barrier for lighting, sockets, and high-power appliances; independent RCD branches prevent a single appliance fault from blacking out the whole unit.
- Hotel guest rooms. A compact recessed board neatly separates lighting, socket, and bathroom circuits, and the transparent cover plus label area lets maintenance staff isolate a room without disrupting adjacent guests.
- Retail and service shops. Convenience stores, restaurants, and beauty salons need a cost-effective final distribution point that meets building electrical acceptance; the standardized layout simplifies inspection and future circuit additions.
Customization
We adjust the number and rating of outgoing circuits, main switch pole configuration, and RCD/SPD inclusion per project schedule. Enclosure material (plastic or steel), recessed or surface mounting, cover style, and circuit labeling artwork can be specified. Logo printing and OEM packaging are supported.
Packaging & Transportation
Boards are packed in fumigation-free plywood crates, reinforced for international shipment. Trade terms: FOB, EXW, DDP; payment by T/T.
FAQ
Q: Can I mix different circuit configurations in one order?
A: Yes. Within one order we can mix models, pole configurations, and cover styles, and volume pricing applies to larger consolidated orders.
Q: Is sample order available before bulk purchase?
A: Standard or simply customized samples are available (not free); the sample fee is deductible from a subsequent bulk order above 20 units.
Q: How do you control wiring and labeling consistency across a batch?
A: Each board follows a fixed harness layout and torque procedure on the same production line, and every unit passes 100% inspection before packing, so breaker wiring and circuit labeling are uniform across the batch.
