F1: Generator Fusing
The F1 generator fusing is a part of building installation and is mounted in the distribution box.
The fuses are small compared to the operating current and operating power. This can be contrary
to the cross-sectional diameter of the power cables that are chosen for the required power supply
resistance.
NOTE: The X-ray generator(s) can only take this high current for a short period of time.
