a) you need to use the value printed on the supply, for the proper *input 
voltage*. The 110 & 220V fuses will differ by 1/2.

b) you need to use Slo-Blo types if possible. Fuses are 5mm X 20mm (standard 
size).

c) since you are fusing the AC input side, that current will be lower than 
the output side (which is a lower *voltage*).
