The fuse is rated to protect the equipment, the supply, and you. Change the fuse for a higher rating and you compromise your safety and equipment and supply safety; increasing the risk of electric shock and of fire.

What happens if you use a fuse that's overrated for voltage but has the correct current rating?

Using a fuse correctly rated for current but "overrated" for voltage does not present a problem. Current ratings are critical safety issues, and fuses should be replaced with those of the same current rating. But using a fuse with an identical current rating but a higher voltage rating is not a problem. The reason for that lies in what the voltage rating of a fuse is. Fuses are given a voltage rating to state a maximum voltage in a circuit that they are designed to protect. And the voltage rating has nothing to do with the "normal" operation of the fuse. The fuse carries current when it operates normally, but when something happens and excessive current flows, the fusible link heats up and opens. This is where the voltage rating comes into play. It is possible that a fuse can arc through when it fails. It is the voltage rating that stands in the way of this. As long as the voltage rating of a circuit is not beyond the voltage rating of the fuse, that fuse will fail safely when it fails. It is acceptable to use a fuse of an equal current rating but a higher voltage rating when replacing a fuse that has failed.

How fuses are rated?

Fuses are rated by amperage (current) and voltage. The larger the current need, the larger the rating of the fuse, to handle the current. The voltage rating of a fuse defines the maximum value of circuit voltage in which the fuse can be safely used. A fuse should not be used in a circuit with a voltage exceeding the voltage rating of the fuse.


What is the rating on the pioneer lcd televisions?

The power rating on the Pioneer LCD television set will differ depending on the model. Larger TV's draw more power, so you should be aware that it may increase your electric bill.


What would be the maximum rating of the incandescent bulb for a dimmer switch?

Find the wattage rating on the dimmer controller. This is the maximum allowable wattage that the lamp in the fixture should be. Lamp wattage ratings under the rated dimmer wattage is fine but do not install a larger wattage lamp that is over the dimmer control's rating.
