  • Cable Sizing | GoHz

    All cables, even for 20 amp load, that originate from the main switchboard near a 200 kVA transformer have to be at least 70 mm² because of the potential short circuit current.. If you use a small cable like 2.5 mm², then a short circuit would totally destroy the cable before the circuit breaker trips.
