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

You should use at least a **100A fuse**. via

## What size fuse do I use for a 2000 watt amp?

**What fuse size is needed for a 2000 watt amp**? With an alternator providing 14.4 volts, you will need a 140A **fuse** for your **2000W** amplifier. via

## What size fuse does a 1500 watt amp need?

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

## How do I know what amp fuse to use?

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. via

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

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

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

10 Amps x 120 Volts = **1200 Watts**. via

## How many watts can a 30 amp fuse handle?

A 30-amp outlet supplies **3,600 watts** (30 amps multiplied by 120 volts). Therefore, the breaker on that outlet could meet code and still trip anywhere between a total load of 2,880 watts (80 percent of 3,600 watts) and 4,320 watts (120 percent of 3,600 watts). via

## 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. via

## How many watts can a 20 amp fuse handle?

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. via

## What if my amp is too powerful?

Amplifiers can be too powerful for **speakers**. As a general rule, if the amplifier produces more electrical energy than the speakers can handle, it may cause distortion or clipping, but damage is unlikely. via

## Will 1000 watt amp drain battery?

A 1000 watt Amp **won't drain your battery**, but a Capacitor is highly recommended. via

## 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. via

## How many watts can a 60 amp fuse handle?

The amount of power that each circuit can handle is the number of volts (usually 120) times the number of amps. Therefore, that 60 amp circuit can handle **7200 watts**. via

## What size fuse should I use for 4 gauge wire?

4 gauge wire is commonly used as a main power wire so it will be used as an example here. Fuse 'A' must be rated to protect wire 'B'. Any fuse rated at less than ~150 amps is sufficient to protect a 4g wire and the vehicle but I generally recommend a **125 amp fuse** with 4g wire. via
