OVERCURRENT PROTECTION IN LOW VOLTAGE ELECTRICAL CIRCUITS
A device providing protection against overloads and short-circuits must be placed where a change of cross-section, type, installation or construction method results in a reduction in the current-carrying capacity (iEC 60364-473).... Generally speaking, distribution panel overcurrent protection devices are rated in such a way as to protect the wiring, not the load devices. Follow-up question: suppose a computer with a 300 watt power supply is plugged into a receptacle, which is serviced by a circuit breaker rated at 15 amps.
