Connectors for 200V dc

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

The exciter electrodes should keep the MAR stable but I agree with you a small load will keep the output voltage in check. I can’t help thinking that as you have the switchboard why not use a hard wired load. There is an American company that still makes DC knife switches, I’ll try to find them if you want.

BTW, I don’t recommend standing in front of an open frame 440V DC breaker when it trips @1500A. Fireproof overalls have there uses.
