Installation

3.1 Electrical Design
3.1.1 Upstream Wiring 

Chargers are considered continuous load devices (EVs draw maximum load for long durations); therefore, electrical branch circuits must be sized at 125% of the load for North American installations, in accordance with National Electric Code (NEC) requirements. (For other regions, refer to local code.) This means that for a maximum 40 A load at 208/240 V output to an electric vehicle, 50 A breaker is required.
Wiring must be sized in accordance with NEC code for continuous load devices. Typically, 16 mm² or 10 mm² (6 AWG or 8 AWG) insulated electrical wire is used, depending upon the rating of the circuit and the distance between the electrical panel and the charger. The terminal block accepts a maximum of 16 mm2 (6 AWG).
