Jcassity, just a question, your multiplication factor of 1.20 was a factor of 20% tolerance?  

not a tolerane actually....
its a standard with nfpa to size an over current protection device.
no matter what your protecting be it analog or digi power supply, if you have some basic info than you can size any dc or ac fuse/breaker.

fuses dont open the circuit as good as a breaker,,, unless its an RK type fuse with a very expensive calibrated filiment.  Breakers always have a ink stamp near the handle of "value" but turn it sideways and look at the name plate data and there you will see thier actual "trip" rating. 


The reason i used 95vac was because thats what your power company will tell you they guarrantee you for voltage.
you could use your prints or wherever you find the operation range manf data.

you could use 100 or 105 for math pruposes only,, not for the application

if this were a college/tech school test question then i would never jot down 1amp for your 40watt device.
its much more electrically correct to use a 3/4amp but........
