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 tapping off a bus bar in a metal panel with lengths less than 3 meters we can size cables according to the down stream overload protection. just as with a motor circuit we can have the main fuses only used for fault protection and can size the cable for the downstrmean overload protection?
