Technical Overview & Specification

Proper site evaluation ensures that electrical infrastructure can safely deliver high power without tripping commercial meters or breaking local electrical codes.

1. Electrical Service & Transformer Capacity

AC 22 kW stations require a dedicated 32A three-phase circuit breaker. DC fast chargers (50 kW - 180 kW) require dedicated sub-stations and high amperage feeds.

2. Grounding & RCD Protection Standards

All installations must incorporate Type B Residual Current Devices (RCD) sensitive to DC leakage currents, adhering to Moroccan safety standards.

3. Cellular Signal & Physical Parking Layout

Sites must have adequate 4G cellular coverage for telemetry. Parking bays require clear bollards, signage, and accessibility compliance.

Compliant with Moroccan national grid (ONE), CNDP Law 09-08 data protection, and international OCPP standards.
