    I've a Peavey 5150 , 2003 USA made, for repair.
    This is an export model for 240V/220V areas, no 110V option.
    The mains lead has a German? integral plug( 2 round pins and a removed earth
    pin but an exposed earthing point) on the lead with a German? socket to UK
    plug adaptor.
    This adaptor is presumably used on other equipment for this purpose.
    Despite BS kite mark etc it is a very vague connection between the earth
    point of the German plug and the UK earth pin. In this one there is no earth
    bonding as it is so easy to dislodge the plug relative to the adaptor and
    losing earth bond.
    Adaptor is SCP3 made by PowerConnections , Harlow, England.
    Needs totally removing German plug and adaptor and fixing a UK plug on the
    lead.

    Yes indeed but doesn`t the socket carry the earth pin not the plug? the
    plug has a female part to accept the earth and an external metal strip
    which is also earth. The idea is that the earth makes contact first (if
    the pin is present in the socket!)

    Isn't that the German plug that 'Brussels' wanted us to adopt in the UK
    to be in line with the rest of Europe?

    No. They wanted a plug that was different to anything else already in use in the
    EU.

    The design of the adaptor is a tiny brass or P-Bronze spring is supposed to
    engage with a recessed earth point on the German plug, a point that an earth
    pin can be screwed into but has to be removed to use this adaptor.

    I had a closer look. Not a screw in earth pin but a push-in pin from a
    socket for earth
    Plug type number? TA-6P , and country ? designations

    I would never use serious equipment through one of these mickey mouse
    adaptors. I'd either change the plug, or use a proper trailing socket and
    plug. Quite apart from any safety issues there's reliability to consider.

    Micky Mouse is right - flimsy plastic adaptor case that allows the German
    plug to move all over the place,X,Y and Z, hence no earth continuity.

    It`s not one of those cheap International travel adaptors from the pound
    shop is it?

    It`s theoretically not possible to insert a two pin plug into a standard
    UK 13 amp three pin socket as the live and neutral pins are protected by
    shutters which require the earth pin to open - OK I know you can fiddle
    it with a screwdriver, but that`s cheating.
    I dont see why we in the UK should change, we have what is generally
    regarded as the best all round mains connector in the BS1363 standard UK
    13 amp plug top[1] The earth pin mates first, it`s fused, the current
    carrying pins are shrouded, so it`s pretty fingerproof[2] and it`s easy
    to wire up, tho almost all new equipment comes with plugs ready fitted,
    and when the plugtops are supplied by decent quality manufacturers, they
    are conservatively rated at 13 amps.-

    [1] The Wylex plug was (I`m told) technically a better design but now
    consigned to history - tho you do still see one or two.

    [2] But not 100%, as I found out the other day whist trying to fiddle a
    mains adaptor out of a confined space in a rack, I managed to make
    finger contact with the live pin! I suspect that was actually a problem
    with the design of the powerstrip rather than the plug.

    just replace the plug with a uk one, if it is to be used there.problem
    solved!
