    Hello

    I currently have a shaving light with a 240v shaver socket built into it which is connected to a lighting circuit.

    I would like to know if it is possible to remove the light and just fit a dual 110v/240v socket to the existing wiring and if so, is there any particular kind I need to get?

    Thanks in advance.

    But don't get the MK one linked to. The 115v socket on the MK ones won't take a UK shaver plug. Why does this matter? Because regulation on such shaver outlets is poor meaning the the 240v outlet rises to 280v on low load such as when charging a toothbrush which could damage it. Toothbrush chargers are generally rated at 100-240v and are best (most safely) charged in the 115v outlet which gives around 140v on low load.

    You must have one to BS61558-2-5.

    It looks like it is but it does not actually say so.


    It doesn't say, therefore it is not suitable for toothbrushes if that is a consideration.

    Can't see why any one won't work with toothbrushes. They are a small load like shavers.

    What is your point?

    Still can't see your point.

    This is absolutely true:

    "Because regulation on such shaver outlets is poor meaning the the 240v outlet rises to 280v on low load such as when charging a toothbrush which could damage it. Toothbrush chargers are generally rated at 100-240v and are best (most safely) charged in the 115v outlet which gives around 140v on low load."

    I'll add the same applies to rechargeable shavers.

    How can regulation be really bad?
    They are just transformers.
    Obviously it depends on the supply voltage.

    They are presumably transformers with fairly high internal resistance/impedance, designed to deliver the 'advertised' voltage when connected to the sort of loads they are designed to supply (i.e. mains-powered shavers). When not loaded, or when having a load much smaller than the 'design load', they are therefore likely to have an appreciably greater than 'advertised' voltage output.

    Kind Regards, John

    Thankyou John. This has come up several times and some while ago i posted photos of a voltmeter plugged into a shaver socket showing the low load voltages.
