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
