    Hi all,

    I need to change a bathroom pull cord switch as my current one is faulty.

    I need to turn off the electrics in my bathroom but i cannot find the pull switch in the fuse board to do this. I can only see the fuse....

    I thought each fuse (switches, cookers) should have a pull switch? Or do i need to turn off the main fuse to turn off of the electric in my home?

    I have attached a photo.

    Thanks all.

    To be sure switch off at the main switch, you have fuses which can be pulled out

    They used fuses and the installation seems to pre-date the common use of MCB's. You can isolate the switch by pulling out the two fuse carriers marked 5A lights, or the main switch to their right.

    I think the fuses used will be cartridge fuses (similar to 13amp plug fuses), which will not be that easy to source if one should blow in the future, so well worth your while getting a set in stock just in case.

    OP - Make sure you prove that the pull cord connections are dead if you just pull the lighting fuses. Dont just assume that the circuits are dead just because you have pulled the labelled fuses, who knows what has been wired to what.

    The fuse holders are marked as HRC holder, HRC = High Rupture Currrent

    HRC fuses are far more robust than plug fuses.

    These are two types of HRC fuse, there are others

    Yes, I know, that is why I suggested sourcing some spares ahead of any future problems. I had in mind a fuse failing on a bank holiday Friday and the OP being stuck for at least four days before replacements could be sourced.

    High Rupture Capacity. (Or HBC is High Breaking Capacity.)
