I’ve been trying to figure out what this connector is and everyone has no clue. There isn’t enough identifying information to find anything on google. All I see is a label “lwai”. It’s located in a panel with power outlets, rj45 jacks, and some audio jacks. I think I found that it might be related to some hvac system but I can’t find any description or picture that confirms that.
1$\begingroup$ do you have a wider picture of what this is? I may be able to find the exact plug. $\endgroup$– user4139Sep 6, 2018 at 19:47
2$\begingroup$ More context about what the connector is attached to could be useful in providing more specific answers. $\endgroup$– user16Sep 7, 2018 at 11:58
Looking at the keys in the socket, I don't think that it is meant for a trailer power cable. It seems to be a dock connector to supply a docked boat with power.
Picture comes from this page.
$\begingroup$ I agree, you can see the thread around the edge... $\endgroup$ Sep 6, 2018 at 20:05
$\begingroup$ I also agree with this. $\endgroup$– user4139Sep 10, 2018 at 23:37
It's an IEC pin and sleeve connector, based on color, pins and ground position it should be 3 phase 120/208V. Google iec pin and sleeve and you'll find mfr guides.
This is a 3 phase power connector with neutral and earth according to the IEC 60309. It's made for 120V/208-144V/250V 50-60Hz Systems. The contact in the top should be ground. The contact in the center could be a pilot contact which might indicate a 63A connector
$\begingroup$ What makes you say this? It surely is a 3 phase connector $\endgroup$– xuma202Sep 12, 2018 at 7:13
$\begingroup$ I think you are right they come in many sockets. $\endgroup$– user4139Sep 12, 2018 at 14:56
That seems to be an industrial plug power, I saw something similar in a milk factory. That can provide highter voltage than a regular plug.
$\begingroup$ Specifically a "16 A 240 V 3P+E+N 9h socket". $\endgroup$ Sep 7, 2018 at 9:16
$\begingroup$ The only reason they provide a higher voltage, is because the phase-to-phase voltage is higher than the phase-to-neutral voltage. E.g. for a normal 220 or 240 Volt lines, the phase to phase-voltage is around 400V. (an increase equal to the square-toot of 3, to be exact). $\endgroup$ Sep 7, 2018 at 12:02
