Why choose 120 volts?

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.
