What is the amperage of a fuse?
The amp rating of a fuse normally should not exceed the current carrying capacity of the circuit. For instance, if a conductor is rated to carry 20A, a 20A fuse is the largest that should be used.

What is a 2 amp fuse used for?
Fuses are commonly available in the following sizes: 2 Amp: Suitable for up to 480 watts (black markings) and used in low power devices like radios and shavers. 13 Amp: Suitable for up to 3000 watts (brown markings) and used in high current devices such as kettles, toasters and heaters.
What are the 3 types of fuses?
Classification of Fuses
Fuses can be classified as “One Time Only Fuse”, “Resettable Fuse”, “Current limiting and non – current limiting fuses” based on the usage for different applications.
What is a 20 amp fuse used for?
A 20-amp screw-in fuse is generally used for outlet and appliance circuits wired with 12-gauge wire. A 30-amp screw-in fuse is most commonly used for circuits supplying electric clothes dryers or air conditioners. These circuits are wired with 10-gauge wire.
What is a 16 amp fuse used for?
The 16A circuit could be for a number of possibilities. Most likely it’s a single socket circuit, an immersion heater, or an oven.
Can I use a 15 amp fuse in a 20 amp slot?
A plug is an object located on one end of a power cord that connects an electrical device to a receptacle. Most household electrical receptacles have a 15-amp rating, but they connect to a 20-amp circuit. You can use a device that has a 15-amp plug with either a 15- or 20-amp receptacle.
What is 3 amp fuse used for?
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.
What is 10 amp fuse used for?
Bussmann 10 Amp ceramic fuse are fast acting fuses with high rapture capacity. They are suitable for various different uses, providing reliable performance and cost-effective circuit protection. They are ideal for use in plugs to protect cables from melting or catching fire if they are overloaded.
What are the 5 types of fuses?
The low voltage fuses are divided into five types and those are of the rewirable, cartridge, drop out, striker, and switch fuses.
What are the different fuse sizes?
Sizes and Amperages
Blade fuses (shown at right) come in six sizes, which are, from smallest to largest: Micro2®, Micro3®, Low Profile MINI®, MINI®, ATO®/ATC® (also called “regular”) and MAXI® or MAX.
How many volts is a 20 amp fuse?
2400 Watts / 20 Amps = 120 Volts.
Can I use 15 amp fuse 20amp?
The answer: It’s possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
What is a 50 amp fuse used for?
A 50-amp breaker can run appliances like ovens, hairdryers, air conditioners, and multiple lights simultaneously while (possibly) still sparing power. The reason for this breaker’s capacity is because it can hold up to 12,000 watts running on a 240-volt circuit (50-amps x 240-volts).
How many amps can a 20 amp fuse handle?
Now, a 20 amp breaker generally can support 2,400 watts per single circuit.
How do I know if I have 15 or 20 amps?
How to check if you have 15amp or 20amp circuit in home – YouTube
What is 5 amp fuse used for?
lighting circuits
5 Amp consumer unit fuses (also known as a Cartridge fuse) are shorter than a standard plug top fuse and are mainly used for lighting circuits.
How many amps can a 10 amp fuse handle?
But a 10 amp fuse may pass 10 amps for many hours and not blow. It may even pass 15 amps for a pretty long time. So 1.5x rated current is just kind of a round number between 1x and 2x. You usually want to keep the fuse either below 80 percent or above 200 percent of its rating.
Can I replace a 10a fuse with a 5a?
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 are fuse classes?
UL Fuse Classification Chart
| UL CLASS | FUSE OVERLOAD CHARACTERISTICS | INTERRUPTING RATING, AMPERES |
|---|---|---|
| CD | TIME-DELAY | 200,000 |
| G | TIME-DELAY | 100,000 |
| K5 | FAST-ACTING | 50,000 |
| H | RENEWABLE FUSES FAST-ACTING | 10,000 |
How do you calculate fuse size?
To calculate a fuse rating, manufacturers work from a simple equation:
- Power (watts) = Voltage x Current (amps) What we really want to know with this equation is the current (amps).
- Amps = Watts / Voltage. So, let’s say we need to work out the fuse rating for a washing machine.
- 850/120 = 7.08 amps.
How many amps can you put on a 20 amp breaker?
16 amps
The standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.
How many watts is a 20 amp circuit?
2,400 watts
20-amp 120-volt circuit: 20 amps x 120-volts = 2,400 watts.
Can I replace a 20 amp fuse with a 25 amp fuse?
I wouldn’t recommend it. Whatever is happening with your plug/socket to blow the fuse sounds like a direct short- and would blow a 25 amp as well. Your best bet is finding out why it is shorting out upon removal, and repair or replace that component.
How many watts is 50 amps?
12,000 watts
50-amp 240-volt circuit: 50 amps x 240 volts = 12,000 watts.
