    I have been given the preliminary design of the small power system for an industrial complex. The design states that a switched fused connection unit should be on its own circuit , would this not normally be part of the ring main? Has anybody seen this before ?

    Depends on what load is on the switch fuse, it's a good idea to have them on here own to prevent loading up the ring, especially in a industrial complex where the ring may be getting used extensively for power tools ect. There are many reasons to put the switch fuse in its own circuit.

    If that's what the designer/ customer wants, that's what you need to quote for.

    The Commercial buildings I work on have many dedicate single SFU circuits.
    It's not unusual at all.

    Can be part of ring or on their own radial, doesn't matter.
