#190343 - Using a 500V socket for a 690V motor
It might surprise to read the "stupid" subject line ! Sorry.

But there is a situation where a panel has to be delivered with a 690 V / 5 Pin / 16A socket ( IEC 60309 ) and we just don't seem to get it in time. So the question.

Someone told that if I use a 32A / 500V socket nothing will go up in smoke - actually the motor will not even draw more than 9A at full load.

1. Is it OK to use the socket with suitable de-rating as above for higher voltage.
2. Is there any document worth its name that confirms this ??



PS : Its really sad to read the thread which talks if is still alive. Change, it seems, is the constant.
