Question: How big of a fuse do I need for an amplifier?

The correct size of fuse to use depends on the amp you are wiring. If your amp has an internal fuse, then your inline car amp fuse should be a bit larger. For instance, if your amp has an internal 20 amp fuse, then you should go for a 25 or 30 amp inline fuse.

How do I choose an amp fuse?

In order to select the right amperage of the fuse, you first need to know the full-load steady-state current of the circuit at an ambient temperature of 25º C (68º F). Once the current value is determined, then a fuse rating should be selected as to be 135% of this value (taken to the next standard value).

What size fuse do I need for a 1200 watt amp?

You should use at least a 100A fuse.

What size fuse does a 1500 watt amp need?

150 Amp A 2500 watt uses a 250 Amp fuse, while a 1500 watt uses a 150 Amp fuse.

Is there a fuse for the amplifier?

Most amplifiers that have internal fuses use some type of automotive fuse. These are the same type of fuses that are used elsewhere in your car, and other audio components, like your head unit, may also use very similar fuses. When you install an inline fuse, you can use this same type of blade fuse.

How many watts can a 5 amp fuse take?

If your lighting circuit at home is protected by a typical 5 amp fuse you can multiply this by the voltage to get 1150 Watts.

How do you size a 12v fuse?

Find the size of fuse by multiplying the amps required by the device (2) by 1.5. 2×1.25 = 2.5 then we will round up to the nearest fuse size (in multiples of 5 amps) which would call for a 5 amp fuse. Cross Reference that fuse size to verify that its below the Maximum fuse size called out by this chart.

What happens if you use a lower amp fuse?

Do not use a fuse with a lower rating-- dont 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 many watts can a 25 amp fuse handle?

20-amp 240-volt circuit: 20 amps x 240 volts = 4,800 watts. 25-amp 240-volt circuit: 25 amps x 240 volts = 6,000 watts.

How can you tell if an 80 amp fuse is blown?

How many watts can a 13 amp fuse take?

3000 watts 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 use a 5 amp fuse instead of a 10 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 is a Type C fuse?

Class C fuses are not dimensionally or electrically interchangeable with other North American fuses. They feature ceramic bodies and bolt-in mounting. They are for short-circuit protection only, in motor controllers, for example, where overload protection is provided by an overload relay.

How do you calculate 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.

Can I use a 2 amp fuse instead of a 2.5 amp?

As long as it is the same size, (physical) and the total amp draw is under 2, yes

Can I use a 30 amp fuse instead of 15?

You MAY be ok with a 30amp in place of the normal 15, but you MAY also burn up some wireing, and/or the whole bike. In any case the work done needs a good going over.

How many watts can a 20-amp fuse handle?

2,400 watts A 20-amp breaker can support up to 2,400 watts on a single circuit. The safe maximum for a 20-amp circuit is 1,920 watts, but circuits should not be loaded to more than 80 percent of their maximum capacity.

Can I use a 30 amp fuse instead of 20?

Do not use a fuse with a lower rating-- dont 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.
