Record charger phase, load, connection method and manufacturer installation requirements.
EV Charging Distribution & Protection
EV Charging Distribution & Protection
EV distribution equipment should be selected as part of the charger installation, with attention to enclosure, residual-current protection, surge exposure and destination-market rules.
01 What problem does this project solve?
EV Charging Infrastructure
An EV charging site rarely means a single charger. Multiple charge points have to be distributed, protected against overload and earth leakage, shielded from surges, and kept working in an outdoor or semi-outdoor environment — all as one coordinated system.
- Multiple chargers on one site
- Power distribution to each charge point
- Overload / overcurrent protection
- Earth-leakage (residual current) protection
- Surge protection
- Outdoor / environmental protection
02 What does one system need?
The devices a complete system requires.
03 How does LAIWO solve it?
One product set, mapped to each protection function.
LAIWO can supply the full device set for an EV charging distribution system from one manufacturer, with the application logic mapped to each protection function. Final device selection stays aligned with the charger manufacturer's instructions and the installation design.
| Project requirement | LAIWO solution |
|---|---|
| Distribution | EV Distribution Box |
| Overcurrent | MCB |
| Leakage | RCCB / RCBO |
| Surge | SPD |
| Isolation | Main Switch |
| Outdoor | IP-rated Enclosure |

Application overview
Start with the system requirement, then select the product.
An EV consumer unit or garage board cannot be specified safely from the number of ways alone. Charger characteristics, upstream protection, earthing arrangement, residual-current protection, surge protection and installation environment all influence the final solution.
LAIWO provides a product path for weather-resistant enclosures and matching protective devices. Final device selection must remain aligned with the charger manufacturer’s instructions, installation design and applicable local requirements.
Selection path
How a requirement becomes a controlled product package.
Each stage reduces ambiguity before samples, technical review and quotation.
Review the protection scheme
Define overcurrent, residual-current and surge-protection needs as part of the complete circuit design.
Select the enclosure
Match ways, mounting, cable entry and environmental protection to the actual installation location.
Confirm documents and labels
Request the relevant model data, wiring information, declarations and private-label requirements.
Frequently asked questions
Questions to resolve before quotation.
What should an EV consumer-unit inquiry include?
Include charger phase and load, installation location, earthing information, required protective devices, number of ways, quantity, destination market and desired OEM scope.
Does every EV installation use the same RCD or RCBO?
No. The required device type and functionality depend on the charger, system design and local installation requirements. Confirm the exact arrangement for the project.
Can weather-resistant garage units be branded?
Branding, labels, packaging and populated configurations can be reviewed as part of an OEM programme after the base model is selected.
