Overload protection

MrJack96

If you have a 32 amp feeder feeding 4x 6 amps circuits feed in parallel is there something in the regs that states the cable between the 32amp fuses dosmt have to be rated for 32 amps as long as It meets certain condition? my thinking was as its limited to 6 amps upstream it’s unlikely to get overloaded.

    I’m trying to get my head straight on this read something about a maximum length of 3 meters and installed in a way to reduce the risk of a fault. So best practice is just to rate the cable to the size of the OCPD?
