Maximum inrush current from power-on (with power-on at any point on the AC sine) and including, but not limited to, three-line cycles, shall be limited to a level below the surge rating of the AC switch if present, bridge rectifier, and fuse components. Repetitive ON/OFF cycling of the AC input voltage should not damage the power supply or cause the input fuse to blow.
