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.

    Am I right in saying this is the same for if you was tapping of a bus bar the overload protection may be downstream so the conductors should be sized to the downstream circuit as long as Fault protection ADS upstream of the cable is in place and the ZS of the cable is met?
