Seems like if the c14 was connected to a 240v PDU the 5-15 would deliver 240v to the equipment, arc/pop tripping the breaker on the PDU as soon as it is connected killing power to everything on that PDU. Or am I missing something?
If you plug a PDU into a service that's higher voltage than expected, why would the PDU circuit breaker trip? That breaker is measuring current, AFAICT, though in the end it might be measuring power. Regardless, it isn't measuring voltage, because that isn't constant (it's AC, after all) and is likely to drop under a short circuit, not skyrocket like the current will.
