The amperage of a water heater is governed by the wattage of the heating elements and the voltage that is applied to them. Amps = Watts/Volts. Once the amperage is calculated, the size of the fuse can be determined.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

It depends on the power of the water heater (in watts).
A low voltage fuse should be rated for 30 amps.
A 13 Amp fuse (brown) is needed for a 3kw heater. <<>> Answer for USA, Canada and countries running a 60 Hz power supply service. 3000 watts at 120 volts = 25 amps, 3000 watts at 240 volts = 12.5 amps.
The fuse rating should be 5 amps
There are zero amps in 1000 watts. Watts are the product of amps x volts or I = W/E, watts divided by voltage. As you can see, that if no voltage is stated no amperage can be given. Once you find the voltage of the heater then use the following equation, Amps = Watts/Volts to find the current draw of the 1000 watt heater.
dnt noe!

5 Amps. If the current passing through the fuse exceeds 5 Amps is should "blow".

You can pull the fuse and take it to an auto sports store for a replacement. There should have a list on the fuse box as to the location of the fuse and how many amps it is, Never replace a fuse with another fuse that is more amps.
You physically can but sit will be unsafe, and will not protect the circuit because it will not blow when it should. Only replace a fuse with the same size fuse.
check the radio fuse (rdo) under the hood, it should be 15 amps
It is in the fuse box loceted under the hood, fuse box cover should give a chart of what the fuses are and the amps.
HCAC fuse should be under the hood
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.
