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

Typical line voltage spec is ±5%. 110 x 1.05 ≈ 115. 

120v has been the US standard since 1967 🙄

120 * 1.05 = 126. 

126 volts is  ≈30% power increase into 110v transformer resistance [which will increase a little from excess power dissipation]

Check your mains voltage and get written certification from the manufacturer that the unit is 120v nominal rated. Insurance companies can be sticklers.
