Hey guys
The air con unit has a start current of 83amps and a running load of 13amps. It's currently wired in 6mm which takes 47amps which is obviously lower than 83amps, would you say this is OK Aslong as the mcb protects the cable.
Saying that if I used a 20amp type C mcb it would take 160 amp to trip within 5 sec and would take 20 secs with 80amp which should be enough time for the starting current. But after its loaded I'm worried that it will take 60 seconds to trip on 50 amps which is not acceptable for the cable.
Any advice or help on this?
