Fuse?

I'm planning on building a fuse into my midibox, I like to be sure :D

Does anybody have an idea at what kind of current the fuse should snap?

aa weell I put a 1A... just in case of some thing go really wrong..

to calculate good value :

mesure the current flow under 5V, and if you have 220V input (like in europe), then muliply the current by 5/220... I think I'm right, but not sure! ;)

I always check the current like that: I dont switch on (the fuse holder is right behind the switch and shortened) and measure the current between the both pins of the switch (so the MB comes on).

Then I just put all LEDs on, the luminence of the LCD to the max and so on and take the current as a basic number. Meaning: If I read like 200-300 mA I use a 500 mA Fuse, if I read 500-800 then 1A and so on.

I always put the fuse behind the wall-adapter, as the most adapters already have short-protection inside.

Hope that helps somehow.
