You have to be careful because equipment voltage rating is different from actual wall voltage. The fuse size is determined from the transformer power rating using the equipment rating and then the wall voltage:
230V x 2.5A = 575VA
Since you are using US 120 volts, the amperage is:
575VA/120V = 4.8 amps
So the 5-amp fuse is correct.
FUSE Question...Very Confused Please Help !
I have a Ceratec Penta Amp ...Made in Germany.
The installed fuse that came with the unit is rated @ 250 Volt / 5A
The Fuse Holder which is under the AC plug states "USE ONLY 250 Volt Fuses."
On back of Amp there are a choice of two fuse ratings:
#1. AC 230:S2.5A
#2. AC 110: S5A
I have it set to #2 setting ....AC 110 : S5A
I am confused. Is this fuse correct ?
Thank you
