Hi Guys...why do some people go for PDU's (which are expensive) compared to receptacles for each machine? Thanks.
Along with what others have said, it's also a safety measure.
My PDUs only allow up to 12amp per outlet, 24a across the whole unit. If one of the miners goes berserk and melts down, it'll trip a 12amp breaker a lot quicker than it will a 30amp breaker. And hopefully not melt all sorts of stuff in the process.
