Do amps matter on fuses?
The most important thing to remember for the fuse holder is that the voltage and current rating need to be higher than what will actually be present on the circuit. If there is a 10 amp fuse, using a 20 amp fuse holder will be no problem; whereas using a 10 amp fuse holder with a 20 amp fuse will likely cause problems.
How many amps does a PSU output?
Well, also the supply side is at a different voltage. It supplies power at 120 volts AC. So, 500W / 120V = 4.1A, it should draw about 4.1 amps to supply the required power.
What amp fuse does a PC need?
Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red). For example: 3A Fuse – Table lamp, standard lamp, television, video, computer, mixer, blender, fridge, freezer, power drill, jig saw, soldering iron.
Can I replace a 1 amp fuse with a 2 amp fuse?
Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components. A blown fuse indicates excessive current has entered the circuit.
Can I use a 10 amp fuse instead of 5 amp?
Possibly yes. It is possible to short out a circuit by overdrawing more than 5 Amp by removing the 5 Amp fuse and putting in a 10 Amp fuse.
What’s the correct amperage fuse for my PC?
It maybe the case that the cable can take upto a rating of 13amps, but ideally you should use a fuse that is slightly higher than the power used (in your case 4A) as some manufacturuers will install 5A or 10A as a standard. Manufacturers will sometimes install an internal fuse for electronic equipment for the purpose of protecting it seperately.
How many fuses do I need for a module?
For example, a module may have a total current rating of 8 amps, but each output is only rated for 2 amps. Going by the book, you probably don’t want to limit your total current at 2 amps, so you put an 8 amp fuse on the module supply, and 2 amp fuses on each output.
When to fuse or not to fuse individual I / O points?
Going by the book, you probably don’t want to limit your total current at 2 amps, so you put an 8 amp fuse on the module supply, and 2 amp fuses on each output. There may also be times when you do not want to fuse a single control point, but rather want a whole group fused together for safety or other sound engineering reasons.
Do you need a fuse for a regulated power supply?
Most regulated power supplies are current limited. They have circuitry that senses the current taken by the load and shuts the power supply down if it exceeds the design limit. They therefore do not require internal fuses. Thanks for contributing an answer to Electrical Engineering Stack Exchange!
