The rated ampacity of the circuit conductors, the full-load current rating of the connected load, and the size or load-rating of the overcurrent protection device for all is actually a two-way street:
The full-load current rating of the connected load dictates the wire size (by rated ampacity) of the supply conductors and the rating or setting of the overcurrent protection or sensing (overload — electric motors) device.
By the same token, the rating or setting of the overcurrent protection device and the rated ampacity of the circuit conductors dictates the maximum full-load current that can be supplied from the service, feeder, or branch circuit in the electrical-power distribution system within a building or other structure.
