## What is a 5 amp fuse used for?

5A Fuse.

Used mainly for lighting circuits..

## How big of a fuse do I need for my amp?

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. Fuse B protects wire segment C….Wire GaugeRecommended Maximum Fuse Size8 awg50 amps10 awg30 amps12 awg20 amps14 awg15 amps7 more rows

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

The fuse rating can be calculated by dividing the power used by the appliance by the voltage going into the appliance. I (Amps) = P (Watts) ÷ V (Voltage).

## What size fuse do I need for a 800 watt amp?

An 80 would be the minimum you should be running. A good rule of thumb to start with is 10 amps/100watts. Sometimes it takes a little more, but that is a good starting point. I have an 80 on my sub amp which just happens to be 800watts and it has never blown a fuse.

## How many watts can a 3 amp fuse take?

700 wattsPlugs 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.

## 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.

## How do I choose a fuse size?

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).

## How do you 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.

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

40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts. 50-amp 240-volt circuit: 50 amps x 240 volts = 12,000 watts. 60-amp 240-volt circuit: 60 amps x 240 volts = 14,400 watts.

## What size fuse do I need for a 1000 watt amp?

HUH? most true 1000 wrms amps call for 80a fusing…..but yours may require less..or more, google for the manual and find out.

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

Add all the fuse values together and you have the max the amps can draw. So if for exapmle the 2000w amp has 2-80a fuses..and the 300w has a 30a fuse..

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

7200 wattsThe 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.
