## What size fuse do I need for a cigarette lighter?

Ever wondered what the appropriate fuse amperage for a cigarette lighter is.

Well, it’s recommended that you use an amp fuse with an amperage between 7 and 10, but never anything over 15..

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

This calculation will tell you how much power the amplifier could output when it is receiving the maximum power from your vehicle’s electrical system. For example, if an amplifier has a single 40-amp fuse, you would multiply 40 by 14.4 to get 576-watts.

## Can I use a 10 amp fuse instead of a 5 amp?

Possibly yes. What ever is wired into that 5 amp slot is rated for a max of 5 amps, overdrawing more than 5 amps by removing the 5 amp fuse and putting in a 10 amp fuse can possibly short out a circuit.

## 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.

## What are the 3 types of fuses?

DC FusesCARTRIGE FUSES. This is the most common type of fuse. … AUTOMOTIVE FUSES. These fuses are specifically designed for automotive systems that run up to 32V and occasionally 42V.RESETTABLE FUSES/POLYFUSE. Like their name suggests, these fuses are self-resetting.SEMICONDUCTOR FUSES. … OVERVOLTAGE SUPPRESSION.

## What type of fuse is best for motor protection?

Time delay fusesTime delay fuses are the most useful fuses for motor branch circuit application. A time delay fuse can be sized closer to motor full load current, providing a degree of overload protection, better short circuit protection, and possible use of a smaller disconnect switch.

## How do you size a fuse for a motor?

You must size the conductors at 125% of the motor FLC [430.22(A)]. You must size the overloads no more than 115% to 125% of the motor nameplate current rating, depending on the conditions [430.32(A)(1)]. You must size the short-circuit ground-fault protection device from 150% to 300% of the motor FLC [Table 430.52].

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

2,400 WattsA 15 Amp breaker can handle up to 1,800 Watts. A 20 Amp breaker can handle up to 2,400 Watts. Many of the breakers you see in the panel run entire rooms. This includes things like standard outlets and built-in lighting systems.

## What size fuse do I need for LED lights?

75mm is good for about 7.5 amps max. I generally like to have at least 100% extra rating so a 3 amp fuse max is what i would use. This should be plenty for 4 leds. If you have working leds but blow a 10A fuse i think your wiring needs checking and you will probably find your fuse is directly across the battery.

## How many watts can a 5 amp fuse take?

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

## Can I put a 3 amp fuse in a 10 amp plug?

The 13A fuse in place of a 10A fuse wouldn’t directly cause any problem – but then, if there’s a problem with the appliance you’re using, or if you plug in too many things and the current goes over 10A but under 13A, then under the new fuse the extension lead will keep working whereas the old fuse would have blown.

## What is a 5 amp fuse used for?

Domestic Appliances Fuse Ratings Coffee maker – 5 amp.

## What are 3 amp fuses used for?

Different types of fuses Plugs 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 I know what size wire to use?

Wire is sized by the American Wire Gauge (AWG) system. Wire gauge refers the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter.

## Which side of fuse is hot?

Fuses can be used either way around, there is no difference between the ends. Except after it has blown, then you can put a multi-meter across the fuse and the end that is being supplied with power will be positive (hot) while the other end will be zero volts (cold).

## 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).

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

Fuse rating = (watts/volts) x 1.25Note the power of the appliance – usually in the appliance manual,Note the voltage (240 volts in the UK).Use the next highest fuse rating after the calculation. Say the calculated fuse rating is 2.2679 amps, use a 3 amp fuse.

## What size Fuze do I need?

The fuse rating should lie somewhere between these two values to allow normal operation but blow on overload. For example, if the normal expected current draw is 10A and the cable size is 25A, then a fuse rated at 15A would be appropriate.

## Can I use a 3 amp fuse instead of a 2.5 amp?

Yup. The fuse is there to protect the wiring and 3 amp is well within the supply wire’s capability. Re: Radio calls for a 2.5 amp fuse.
