Connectors for 200V dc

davidwalker2
I have an installation that uses 200V dc (balanced about earth but not earthed). All the installed equipment is direct wired, but I have an application that needs a plug and socket.  I don't want to use the standard connectors that are also used for ac to avoid ac equipment being plugged in inadvertently.  The equipment in question will draw a current around 8 amps and is metal framed, not double insulated so needs an earth.  I would be grateful for any suggestions/ advice.


I am sure that this has been discussed previously, but I cannot find it on the old forum.


Many thanks,


David

    Purple Ceeform plugs and sockets are readily available but are designed for nominal 24/25 volt circuits. In practice used for AC or DC but only for up to about 28 volts maximum, such as a 24 volt battery on charge. Not suited for 200 volts.


    White Ceeforms for nominal 50 volt systems also allegedly exist, though I have never seen one.


    As only one socket is needed I still feel that a BS 543 15 amp outlet is the best solution, look for an old one that incorporates a DC rated switch, fleabay is your friend ! Or a modern UNSWITCHED type with a DC rated switch adjacent. A modern 15 amp socket with an integral AC only microgap switch would not be suitable.

    A BS 543 type outlet would also look more suitable in a heritage situation.
