Using IEC reference method A and B for loose wires in conduit a I have derived the following max OCPD and in turn maximum current loading for general use circuits:
1.5mm2: 10 amp MCB reference method A, 16 amp MCB reference method B
2.5mm2: 20 amp MCB (Both A & B)
4mm2: 25 amp MCB reference method A; 32 amp MCB Reference B
6mm2: 32 amp MCB reference method A, 40 amp MCB reference method B
10mm2: 40 amp MCB reference method A, 50 amp MCB reference method B
16mm2: 63 amp MCB reference method A, 70 amp MCB reference method B
Do my numbers sound correct? I may have rounded a few numbers in method B, so A would probably be the best approach. Just double checking.
