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 use a 3amp fuse in a 13amp plug?
A 3A fuse is the safest to use and should be used for appliances at 700w or less. Appliances rated above 700w should use a 13A fuse. Be extra cautious when using a 13A fuse and try using a 3A fuse if and when it’s possible.
What size fuse do I need for a fridge freezer?
Some appliances, such as lamps, televisions, computers, fridges and freezers generally require a 3 amp fuse. However washing machines, dishwashers, microwaves, kettles, toasters and irons usually require 13 amp fuses.
Can I use a 5 amp fuse instead of a 3 amp?
You can but you shouldn’t, it can cause wires to heat up and possibly cause a fire. You can replace a 5 amp with a 3 safely as long as you don’t exceed 3 amps.
What amp fuse does a dishwasher need?
13amp
Plugs for appliances rated between 700 watt and 3000 watt should be fitted with a 13amp fuse. 13A Fuse is used for washing machine, dishwasher, microwave, kettle, and toaster.
Can I replace a 10a fuse with a 3A?
Yes, but you diminish the intended protection. You are allowing 30% more power to flow before the fuse pops. This could be the difference between internal part survival and failure.
What does 3A fuse mean?
A 3A fuse is supposed to break the circuit for any current higher than 3 Amps. So replacing the fuse by a 5 A wire will allow more current than the rated value through the system and might damage appliances or trigger a higher protection scheme to act promoting larger blackout.
How many amps does a fridge freezer use?
Ratings of commonly used household appliances
| Domestic Portable Appliance | Amps Used | Watts Used |
|---|---|---|
| Fridge Freezer (Standard) | 1.5 | 150 |
| American Style Fridge Freezer | 2.5 | 250 |
| Kettle | Up to 13 | Up to 3000 |
| Satellite TV box/ Streaming devices | <0.5 | 30 |
What amps does a freezer use?
A 10 cubic foot freezer will typically use around 1.5 to 2 amps when running. Upon start up, a 10 cubic foot freezer will use around 4.5 to 6 amps.
What household items use a 5 amp fuse?
If this is the case in your house, you should use 5 amp wire for a lighting circuit, 15 amp for an immersion heater circuit, 30 amp wire for a ring main or cooker circuit (for cookers up to 12 kw).
Can I use a 2 amp fuse instead of a 3 amp?
It’s perfectly safe but you may be drawing a higher current than what the circuit is rated at. This will cause the fuse to blow much sooner than ever expected.
How do I choose the right fuse?
How to Choose the Right Fuse
- Identify the type of voltage that is being protected.
- Observe the amperage of the electrical circuit that the fuse will be protecting.
- Size the fuse to its particular holder.
- Inspect the fuse for internal element replacement.
- Use a fuse that has an inspection window.
How do I know what size fuse to use?
B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125% = 100A. C Choose FUSE AMPERAGE near the middle of this range.
What size breaker is needed for a dishwasher?
The dishwasher needs a single-pole breaker that has at least 15amps. If you operate the dishwasher on the same circuit breaker as the garbage disposal, you need to use a 20 Amp breaker.
Can I put a 5a fuse in a 10A plug?
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 10A fuses used for?
A 10 amp fuse will be used to power and protect a circuit that requires a maximum input current of 10 amps. If due to an electrical fault or overload, a current that is significantly over that rating of 10 amps, the fuse will blow – cut off power by destroying itself.
Can I use 10A fuse instead of 12A?
3 Answers. Never replace a fuse with one rated for a higher current. If you can’t find a 12A fuse try a 10A fuse. The fuses are to protect the wiring, not the downstream devices.
What happens if you use a higher amp fuse?
If you use a fuse with the wrong amperage, the fuse won’t blow as intended, damaging the circuit and resulting in a much larger repair bill. Rather than risk blowing the circuit, take the car to a repair shop to determine what is causing the fuse to repeatedly blow.
What happens if you use a lower amp 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.
Can you use a bigger fuse than recommended?
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.
How many amps does household appliances use?
In most homes, lighting and small appliance circuits are 15 or 20 amps, and major appliances are on 20, 50 or even 60 amp circuits.
