I know what would happen. The three amp fuse would blow. Any device that is plugged into a receptacle with out having sufficient resistance to limit the current flow will dead short the circuit and cause the breaker that feeds the circuit to trip. In this case the fuse being of a lower rating that the feed breaker the fuse will blow without tripping the receptacle's feed breaker.
A standard 3kW immersion heater will require a fuse rating of 13 A. This is because, it draws a current of 12 A.
It is possible that the sand may fuse together into larger conglomerations of sand, or rough glass.
If a thick copper wire is used in a fuse then by definition of a fuse this device would no longer be defined as a fuse. A fuse in a circuit is used to protect the conductors feeding the load of that circuit. The circuit, if using a thick copper wire in a fuse, would then be considered as a non fused circuit.
It will "open". this will stop current flow. Most folks say you have a blown fuse or the fuse blew (blue?) which is actually incorrect.
fuse
The fuse will blow as soon as you turn it on. Use the correct fuse and nothing else.
12 to 13 amps
12a
In the YUK an electric kettle has a 13 amp fuse., together with a 250 voltage. However, in the USA the voltage is lower and so ther fuse amperage may be different.
fhhjjf

The device will work, but the 3A fuse will blow quicker than the 5A would have.
Your telling us ask us anything you just put stupid questions

it takes quite a bit more amps to create heat vs light
Please do not ask such questions that are impossible to solve.
Because boiling water takes a lot more energy than reading and spinning a dvd disc.
