Can a fuse be replaced by a piece of wire?

No, the electrician should not be allowed to replace the fuse in the house with a piece of wire. A fused filament must have a low melting point such that it could melt and break in response to a large amount of current. Most of the wires have high melting points and hence a wire cannot be used to replace the fuse.

What can I use instead of a fuse?

A circuit breaker can be used and an ON/OFF switch. A blown fuse can be easily replaced with the wrong size, or even jerry-rigged (using a wire or small copper bar to replace the fuse) creating a safety issue.

What fuse do I need for 12v?

if the device load is known in watts, divide the wattage by voltage-(i.e 100watts divided by 12v = 8.3 amps) -use 10 amp fuse.

How many amps does a microwave use?

10 Amps
The microwave ovens consume power at a rate of 650– 1200 watt, which equates to a current of around 10 Amps.

How is a fuse wire different from a copper wire?

Fuse is basically a piece of wire of a material with a low melting point. On the other hand, copper wire cannot be used as a fuse wire because it has a high melting point(1094 deg C approx). Copper will not melt easily when a high electric current passes through it and may damage the electrical appliances.

What can I use for fuse wire?

The material used for making fuse element has a low melting point such as tin, lead, or zinc. A low melting point is, however, available with a high specific resistance metal shown in the table below. The material mainly used for fuse element are tin, lead, silver, copper, zinc, aluminum, and an alloy of lead and tin.

How do you make a simple electric fuse?

It is quite easy all you have to do is make a circuit with a bulb. Attach the negative wire to the led bulb attach the positive wire to some steel wool. and attach one wire between completing the circuit. If the circuit works either the steel wool strand or the led should break the circuit.

How do I determine the size of a fuse wire?

Find the items that you’re installing and their current requirements. Add the values and divide by 1000 to get your total current in Amps. You can use this value in the fuse size chart above to determine the minimum wire size required.

Do you need an electrician to replace a fuse?

While it can be a pain when a fuse blows, remember that it is happening for your safety. It is advised that you have an electrician complete any electrical work in your home. But if you are choosing to replace the fuse yourself, ensure that you use the correct rated fuse wire and not copper wire.

Why do I need a fuse for a 150 watt bulb?

You install a fuse to PROTECT the WIRE!!!!!! That means FIRST you determine what size WIRE you need based on the Length of the wire run to the 150 watt lights. If there is some pre installed factory wire and you have changed the lights. The FUSE size for that Factory wire has already been determined and should NOT be increased!

What is a fuse and how does it work?

Effectively a fuse is a safety device that protects your wiring and appliances, and also prevents electrical fires from occurring. A fuse contains a thin piece of wire that is designed to carry a limited electrical current. If there is a fault and too much current tries to flow through it, then the wire will heat up so much that it melts.
