Can you use 20 watts or 30 watts in a fuse?

No, watts are a measure of power while fuses are rated in amperes (amps). To determine the fuse rating, you need to calculate the current in amps by dividing the power in watts by the voltage. Then, choose a fuse that is rated equal to or slightly higher than the calculated current in amps.


How many watts for a 25 amp fuse?

# 10 wire is rated at 30 amps. Code states the the wire is only to be loaded to 80%. 80% of 30 = 24 amps. If distance is a factor then the resistance of the wire comes into play. Go up one size to #8 rated at 40 amps, usable 32 amps.


Fuse to protect 110 volt from 220 volt?

Using a fuse will not protect a 110-volt appliance from 220 volts. You will need a voltage converter or transformer to step down the voltage from 220 volts to 110 volts to protect the appliance. It is important to use the correct equipment to ensure the safety and proper functioning of the appliance.


Can you use a MDL for MDA fuse?

Depends on the voltage across the fuse. For fuses rated below 9 amps, the two types are almost identical (MDL has slightly lower AC Interrupting amperages), and both are rated for use up to 250V. For fuses rated above 9 amps, the MDL fuses are rated for use up to 32V, while the MDA fuses are rated for use up to 250V. More info on Cooper Bussmann (link below).


Low volt fuse to high volt fuse?

I'm not sure of your question here. If you are asking if you can replace a fuse with a fuse with a higher voltage rating, the answer is yes, but it probably won't fit in the same terminals. The voltage rating must be the same or higher than the voltage applied.

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.

If a 50 amp fuse rated 32 volts is used in a 12 volt circuit at what amperage will it fail?

The fuse will fail at 50 amps regardless of which voltage you use.

What is T1.25AL fuse means in terms of voltage and current rating?

Most `T' fuses are rated in either 125 volt or 250 volts A.C. If you look at the metal end cap on one of the ends, it'll specify which voltage it's rated. The 1.25, is 1.25 amps at the rated voltage.


What size fuse should be used for 2 amp power supply?

If the 2 amps is the output amperage of the power supply, the maximum that should be drawn from the unit is 2 amps. The load amperage that is connected to the power supply should govern the amperage of the fuse used. There is not much range there, the fusing could go from .25 to 2 amps. If the input amperage is 2 amps then the input and output voltage of the power supply should be stated.

What is the fuse rating for 3kw immersion heater?

The fuse rating for a 3kW immersion heater is typically 13 amps. This is based on the formula that calculates the current draw (I) using the power (P) and voltage (V): I = P/V. For a standard UK voltage of 230V, a 3kW heater would draw approximately 13 amps. It's important to ensure that the circuit is also properly rated to handle the load.
