Project Background
This was an export batch of distribution panels for a warehouse in Colombia. The panel designation is AL-A1, feeding the warehouse lighting and socket circuits. The destination grid is 120/240V single-phase, which differs from the 220/380V three-phase system used in China, so component selection, circuit division and cable sizing all had to be reworked for the local system.
The difficulty with export work is that once the enclosure ships, there is no rework capability on site. Circuit labels, the single-line diagram and warning markings must all be correct before dispatch, so the panel can be installed and accepted on arrival.
Customer Challenges
- A different voltage system means domestic configurations cannot simply be copied; circuits and protection settings had to be recalculated for 120/240V single-phase
- No fabrication capability on site – unclear labels or missing drawings mean rework during installation
- Local electricians do not read Chinese, so circuit identification had to be bilingual
- Socket circuits involve personal safety and require residual current protection
Xiaoyang Solution
- Local-system configuration: MCB-C63A/2P incoming main, MCB-16A/1P lighting branch circuits, RCBO for socket circuits (RCB-C20A/2P, 30mA / t=0.1s), plus spare ways
- Component selection: Schneider iC65 series breakers on DIN rail, modular layout, so equivalent parts can be sourced locally for later expansion or replacement
- Bilingual circuit labels: “Main”, “Lighting”, “Socket”, “Backup” in English with Chinese alongside, so local electricians can work without reading Chinese
- Single-line diagram inside the door: the full diagram is fixed to the inside of the door, showing circuit numbers, cable spec (BY-3×2.5), 120V lighting circuits and the “AL-A1/A2 surface mounted, 1.5 m above floor” note for on-site installation and acceptance
- Internal workmanship: separate PE and N terminal bars, yellow and blue colour-coded conductors, tidy wiring for easier troubleshooting
- Safety marking: bilingual warning label on the upper left of the enclosure – “Warning / WARNING”, “Do not touch”, “Danger, live voltage” – plus a “Danger, live voltage” label inside
Delivery and On-site
Three actions were completed before dispatch: every circuit label applied, the single-line diagram fixed inside the door, and warning markings in place. The enclosure is matte light grey with a surface-mounted lock and a metal nameplate at the lower front recording model and production details, ready to energise once installed.
