    The fuses aren’t to protect the circuit, they protect the end and intermediate devices. The breakers protect the actual circuit.

    E.g. you’ve got a thin flex for a low power lamp. You don’t have to worry about a short allowing 40A to flow down a 2A cable.

      How many cheap import lamps do have an appropriate fuse?

      And the short circuit 40A is better covered by a fast-acting breaker.
