What is fuse explain with figure?
An electric fuse is an electric device which interrupts the flow of current in an electric circuit. A fuse is usually a short piece of wire. The fuse is made up of a material which has high resistivity and low melting point, so that it melts down due to overheating of the wire during high current flow.
How many types of fuses are there?
The low voltage fuses are divided into five types and those are of the rewirable, cartridge, drop out, striker, and switch fuses.
What happens if you use a lower fuse?
Do not use a fuse with a lower rating– don’t put a 20 amp fues in a 30 amp circuit–because it probably will blow prematurely. Conversely replacing a 20-amp fuse with one rated at 30 amps is dangerous because it may not blow soon enough and damage an electrical component or start a wiring fire.
How to choose the size of your fuses?
HOW TO CHOOSE THE SIZE OF YOUR FUSES. Easiest Way. A lot of components will tell you how big of wire and what kind of fuse to use. If this is the case, follow it. Easy Way. Find the continuous amperage of the device you are trying to power and multiply that number by 1.5, then round up to the nearest fuse size you can find.
How do you know if you have a fuse box or circuit breaker box?
Determine if you have a fuse box or a circuit breaker box. Once you’ve found your box, open the door. If you see rows of switches, you have a circuit breaker box. Fuses are round and screw into sockets in the fuse box, much like a light bulb.
Is the fuse size dependent on the load?
One common misconception about choosing the correct fuse size is that it’s dependent on the load of the circuit. Actually, the load of the circuit should have nothing to do with choosing a fuse size.
What’s the average size of an ANL fuse?
These are typically used for lower amperage devices and the most common size seems to be 15 amps. ANL fuses come in sizes from 35 – 750 amps. They are typically less expensive than Re-settable Breakers .
