    Safe Isolation of a 16/32a socket

    Removing someone else's isolation

    Hi all, After some help here. My boss at the company I work for is adamant that I must remove my electrical isolation, even though I don't deem the work to be safe or complete. Long and short of it is, if I don't remove it myself, then someone else will. Is this legal? Many thanks
