If the fuse is blown, replace the fuse with one that is exactly the same (see panel). Make sure to note the fuse amperage and voltage ratings, which should be marked on the fuse itself (Figure 3) or on the panel label near the fuse holder.

How do you determine which fuse to use?
You’ll usually find the fuse rating on the side of your fuse, which will be given in amps. Fuse rating is the amount of current needed for the fuse to blow or break.
Can I replace a fuse with a higher amp?
Never replace a blown fuse with a higher-amp fuse. Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement.
How do you determine what size fuse you need?
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.
How do you tell what size fuse you need?
The simple calculation is watts divided by volts equals amps. After you have calculated this, it is a simple case of adding around 10% to the value and choosing the nearest fuse to match. This is a more precise method then just guessing should you require a 3, 5, or even 13 amp fuse.
Can I replace a 15 amp fuse with a 10 amp fuse?
Can I use a 10 amp fuse in place of a 15 amp in my car? – Quora. You can, it will may immediately blow, but it won’t hurt anything other than the fuse.
Can I replace a 15 amp fuse with a 20 amp fuse?
Most likely you can. However, you have not asked the right question. It would not be a good idea to replace a 15 amp fuse with a 20 amp fuse. If you do and you actually load to circuit to more than 15 amps, you will shorten the life of the insulation and increase the risk of a fire.
Is it OK to use a bigger 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.
What are standard fuse sizes?
Standard sizes for fuses and fixed trip circuit breakers, per 240.6, are 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800, 1000, 1200, 1600, 2000, 2500, 3000, 4000 5000, and 6000 amps.
What are the different fuse sizes?
Size groups
| Blade size | Blade group | Common ratings (maximum current) |
|---|---|---|
| Micro2 | APT, ATR | 5, 7.5, 10, 15, 20, 25, 30 |
| Micro3 | ATL | 5, 7.5, 10, 15 |
| LP-Mini (low profile) | APS, ATT | 2, 3, 4, 5, 7.5, 10, 15, 20, 25, 30 |
| Mini | APM, ATM | 2, 3, 4, 5, 7.5, 10, 15, 20, 25, 30 |
What is are the various types of fuse?
Fuses can be divided into two major categories, AC fuses, and DC fuses.
What is 13 amp fuse used for?
Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse Washing machine, dishwasher, microwave, kettle, toaster, iron.
Can I put a 13 amp fuse in a 3 amp plug?
The plugs are marked as such because they can handle a maximum of 13A of current. It is a mistake for people to assume that a 13A fuse should be used in this appliance.The power rating is so low that we can quickly see that the fuse is too high and needs to be changed to a 3A one.
Can I use 3 amp fuse instead of 5 amp?
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.
What happens if I use a 15 fuse instead of 10?
A higher rated fuse will let more current flow through the wires than the wiring is rated for, which will heat it up and could cause a fire. You better find out whats drawing more than 10 amps of power and fix it.
What happens if I use the wrong fuse?
Fuses are present to protect the components of the electrical system. Rather than destroying the circuit when there is a surge of power, the fuse blows to protect it.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.
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.
Can a microwave be on a 15 amp breaker?
What’s the Danger? A microwave plugged into a 15-amp circuit could cause the wires in the wall to overheat and present a fire hazard. More likely, however, the microwave will trip the 15-amp breaker and pose a regular nuissance. Note that you should never just replace a 15-amp breaker with a 20-amp breaker.
Can I put a 30a fuse in a 20a?
If you put a 30 amp fuse on a circuit with 20 amp sockets, the socket becomes the new failure point when you exceed 20 amps, and you risk an electrical fire. Don’t do it. Probably not a problem.
Can I put 30 amp fuse in 15 amp?
In fact, a 20 or 30 Amp fuse or breaker on a 15 Amp circuit becomes an armed fuse of a ticking fire bomb!You replace it with another 15 Amp one. It blows again and again. Now you replace it with a 20 Amp fuse.
Can I put a 15 amp fuse in a 20 amp slot?
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.
