⚙️ Why Choose a 32A C Curve EV-Optimised RCBO?
Electric vehicle chargers can generate short bursts of high current during startup. The included C Curve EV-Optimised RCBO is engineered to manage this inrush without false tripping, offering more consistent charging uptime and protection.
As always, proper earth fault loop impedance (Zs) values must be confirmed during installation. In typical domestic installs—especially when the unit is close to the main electrical intake—Zs compliance is usually not a concern. That said, only a qualified electrician should conduct these measurements.
📘 Note: All technical advice is a guideline only. Refer to the most current BS 7671 standards and work with a qualified installer.
