In the context of electrical systems, understanding the terms "load side" and "line side" in relation to overcurrent protective devices is crucial. When a generator supplies power to a separate building, the overcurrent protective device (such as a circuit breaker or fuse) is typically located at the generator.

In this scenario, everything that is downstream from the overcurrent protective device, which includes the feeder leading to the building, is considered to be on the load side. The load side is defined as any point in the electrical system that is downstream of the protective device. Therefore, since the feeder is providing power to the building and is thus connected to the generator output, it falls on the load side of the overcurrent protective device.

This understanding aligns with the fundamental concepts of electrical distribution, where the delineation between load side and line side is based on the relationship concerning the protective device. In essence, if you are considering the flow of electricity from the generator through the protective device and then to the connected load (the separate building), the feeder is operating on the load side.
