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.

    IF the total load cannot exceed the 4 lots of 6A at once, that is to say 24 A, it is OK to use a cable rated for that, indeed the 32A breaker could probably be bigger so long as it still provides short circuit cover for that cable. But woe betide someone just adding another load to that second board without thinking too hard.

     So I'm with Broadgage - it is OK, and to regs it is perfectly acceptable, but not the sort of thing many people want to see or do. if they can avoid it.
