I'm not an electrician and I've only installed an unfused and unswitched IEC plug, but here's how I think it should be wired up.
Power from wall -> IEC plug -> fuse -> switch -> your device (power)
Neutral from wall -> IEC plug -> your device (neutral)
Ground from wall -> IEC plug -> your device (ground pin) and any other devices in the cabinet that need earth ground (e.g., metal cp)
I'm not even going to try chicken scratch!
