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

    An alternative I have had suggested is to use a 16A 3-pole Schuko plug and socket.  It is a controlled, industrial situation, and we do not have any equipment on site that uses continental-style connectors, they are readily available and cheap.  Any thoughts?

    Perhaps a little caution using the Shuko plug ... many standards for equipment that we use for mains are specified for AC applications only (some are also not specified for ELV use). This is certainly the case for the BS 1363-series.


    More information on suitability of some of the "usual" accessories standards and their suitability for DC applications can be found in the following FREE publication from the IET: https://www.theiet.org/publishing/iet-standards/built-environment/practical-considerations-for-dc-installations/
