Copper conductors only, rated min. 75°C. Follow NFPA 70 (NEC) or CSA C22. 1 part 1, and all local
codes. For DG breakers larger than 20 A, use wire insulated for 90°C based on 75°C ampacities.
NOTE: The IQ Gateway is pre-wired to a 15A breaker in the IQ Combiner. Any additional load installed on this breaker should use a cable size of 14 AWG. The
typical current drawn by the IQ Gateway is 20mA. The maximum continuous current of all loads protected by this breaker should not exceed 12 A. When
adding additional loads to the breaker, the installer must comply with all NEC and local electrical codes.
