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

    Someone will post that BS 7671:2018 doesn't have those colours identified in Table 51, so you'll have to wait for Amendment No. 1 (if they are to be included in there ... who knows?) - however, if you look closely at the Corrigendum to BS 7671:2018, there is a Footnote to Table 51 which I think might serve your purposes if you wanted to use the BS EN 60445 colours in the near future. In any case, I guess it's a current British Standard that affords equivalent safety (provided there's no confusion in your installation - perhaps the BS 7671 required label "This installation contains colours to a number of different standards. Great care ..." etc. - or whatever the words are ?)
