To all the sparky's, i have a 3 phase ac unit which is wired with 2.5mm cable on a approx 16 metre distance from meterbox. As i understand this cable is rated at 20 amps yet brivis states the ac unit must have a 32amp breaker which it does as not to trip on start/up? is it legal to have such a breaker size on 2.5mm cable or should have the cable have been upgraded to cover the 32a breaker.
