## What amp fuse do I need for my 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.

## What fuse should I use for stereo?

Most low-powered radios can use a 20-amp fuse without any issues. However, for high-powered stereos — those that produce 100 watts of power or more — you may have to use a 25- or 30-amp fuse. You may be able to use a wire clasp or harness already under the dash to secure the wiring from the radio to the fuse box.

## How do I choose a fuse for my amp?

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 1000 watt amp?

What fuse size is needed for a 1000 watt amp? With an alternator providing 14.4 volts, you will need a 70A fuse for your 1000W amplifier.

## Can I use a 10 amp fuse instead of a 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.

## 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.

## What fuse to use?

For an appliance rated as 700W or less, a 3A fuse should be fitted. For appliances above 700W, a 13A fuse should be fitted. One complication of using the 700W rule is that some appliances can draw a higher current when they are first switched on (inrush current).

## How many watts can a 40 amp fuse handle?

40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts.

## How many watts can a 10 amp fuse handle?

10 Amps x 120 Volts = 1200 Watts.

## Can I use a 5 amp fuse instead of a 13 amp?

If your circuit is rated at 13 Amps or higher then you can replace the 5 amp fuse with a 13 amp fuse. You certainly can and if there is a reason that the 5 amp fuse blew, you will turn the item that the fuse is designed to protect into a melted mess and all the magic blue smoke will escape.

## How do I know what kind of fuse I have?

Look for “Class RK1” printed on the fuse. These fuses can be recognized by their cartridge shape or blades used for slot mounting. Look for “Class RK5” printed on the fuse. These fuses can be recognized by the round body with blades where they can be bolted in place or in its cartridge version.

## Why is it dangerous to use the wrong fuse in an appliance?

Fuses. Electrical circuits rely upon the correct use of circuit-breakers, called fuses, to cut the power to the appliance in the event that something goes wrong. This is because when an electrical appliance goes wrong, it can heat up more than it normally would, which has the potential to start a fire.

## What is a 5 amp fuse used for?

5 amp sockets are used on the lighting circuit, meaning they are switched on and off with the light switches in the room, rather than being used like regular plug sockets. They are designed for appliances that take less than a 5 amp current, for example floor lamps, table lamps and fans.

## 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 it’s below the Maximum fuse size called out by this chart.

## What gauge wire should I use for a 2000 watt amp?

So, for a 2000 watt amp going by most charts you will need between 4 gauge wire to 00 gauge wire depending on how far you are going. If you are only going 0-4 feet that is when you can get away with the smaller wire, but anything beyond that you will need thicker wire. 2 gauge can be used for 4 feet to 10 feet.
