Power cable shutting amp down


I just put in a JPS Power AC+ and it seems to be overheating the amp. I've swapped in the Shunyata Python and that does not do this. I've put the JPS on the preamp when I do this?

Anyone heard of this behavior.... stock cable seems fine. You think this is a bad cable?

JPS got back and said they would take care of it in under five minutes from when I emailed them.
if it was the male IEC in my amp when I switched power cords the amp would still shut down. When I switch cords it does not shut down.
If componant parts are manufactured to a tolarance of +- 5% and speced to +-7%. The IEC male could be minus all the way to its extreme tolerance and still spec good. One cable could measure to the minus limit and the other to the plus limit. You could end up with a zero fit or a 15% loose fit and still be within limit. Not too confidence building is it ? ? ?
