Hi, I have a question about Nema receptacles and non-standard voltages.
I have some European equipment that requires 400V 3 Phase power. I require locking receptacles/plugs with this equipment and plan on feeding it via a 600-400V Transformer. I was thinking of specifying a NEMA L16-20 receptacle/plug which is meant for 480V 3 Phase. My question is are there any issue with using this for 400V Equipment or is only 480V allowed? My initial thoughts are that the receptacle will be fine with 400V since it is rated for 480V, so from that standpoint it is fine. However another purpose of these receptacles is to ensure that the incorrect voltage and current is not connected which is why they are unique for every combination of voltage/current rating.
Wanted to get others thoughts about this.
