I have a 12Volt 20Amp 240Watt regulated power supply to use for a table top pinball game - comprising of solenoids (2@ 12V 8A peak), some LEDs and a micro controller. The unit has an internal fuse but I also need a fuse for the AC IEC socket (which has an on-off switch and separate fuse) on the back of the cabinet, and also one for the main wall plug.
If fuses are rated approx 125% of the normal operating current:
(240W/240V) * 1.25 = 1.25A
Would a 3A fuse be fine for both the socket and the wall plug, or should I use a different combination?
