I want to install USB charging ports in the back of a row 60 lockers.
I want each locker to have 2 usb ports, up to 2 amps per port.
I also want each locker to have its own automatically resetting overload-breaker, so that if one locker gets overloaded, it simply waits a few moments and tries to reset, or it waits until the phone is unplugged, and THEN resets. (I don't want to have to reset it manuallly, and I don't to let it bring the whole system down)
60 Lockers * 2 usb ports * 2 amps per port = 240 amps
Should I get a massive 5 volt power supply to power all the USB ports in parallel with a little DC circuit breaker attached inline with each port?
Should I keep the electricity plain old 110AC and then just literally have an over-the-counter phone charger connected behind each locker?
Should I have a massive 12V DC Power supply to power everything in parallel and then have conceptually a car-charger behind each locker?
Conceptually, what do you think is the best way to do this, for economics, reliability, and not letting an over-load bring down the whole system?
