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.

    That's the condition for omitting a fault protective device.  Confusingly it's duplicated in the section on positioning overload devices downstream, but it's really just saying you still need to consider fault protection upstream (or omit it according to the rules for fault protection).
