## Can a 5 amp fuse instead 3?

No.

The current rating of a fuse means the fuse will open when the rating is hit.

…

Fuses protect the equipment being used as well as the power side of the circuit.

If you need to use something NOW and the fuse is a 3 Amp slow blow you could use a 5 Amp fast blow without much worry..

## 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.

## Can I use a 13a fuse instead of a 3a?

For an appliance rated as 700W or less, a 3A fuse should be fitted. For appliances above 700W, a 13A fuse should be fitted. … BS1363 has standardised on just two preferred fuse ratings, 3A and 13A, however any fuse rating up to 13A can still be used.

## 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 10amp fuse in 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. If there’s a short-circuit it’ll be more than 5 amps, or 13. …

## 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 amp 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 much current can a 13 amp fuse take?

BS 1362 Fuse Operation Characteristics In fact a 13A fuse will allow a current of 20A to pass indefinitely without blowing.

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

You’ll usually find the fuse rating on the side of your fuse, which will be given in amps. Fuse rating is the amount of current needed for the fuse to blow or break. When this happens, it stops the electrical power from flowing through the electrical circuit.

## What size inline fuse do I need?

If your amplifier has an internal fuse, then your inline car amp fuse should be a little bit larger. For instance, you might want to use a 25 or 30 amp inline fuse if your amp has an internal 20 amp fuse.

## 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.

## 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.

## Can I use a 2 amp fuse instead of 1 amp?

The real answer is NO. The manufacture put a 1 amp fuse in the unit because the typical draw is much less than the 1 amp and the fuse blow will be an indication of trouble coming.

## Can I replace a 5a fuse with a 13a?

not it’s not. the device can’t take more than 5A that’s why it has a 5A fuse. if you put a 13A fuse in the device might take upto 13A before the fuse blows and more than likely you’ll fry it.

## How do you size a 3 phase circuit breaker?

For 3-phase loads, you divide the VA by the nominal voltage and by the square root of three (approximately 1.732). If your total 3-phase load in a 480V system is 50,000VA, what size breaker do you need? 50,000VA ÷ (480V × 1.732) = 60.2A.

## How do I know what breaker I need?

Circuit breakers have markings stamped on the side of them and are usually located inside the panel cover door. There is a label that will tell you what type of breaker is needed for installation in that particular panel.

## How do I know what size circuit breaker to use?

To calculate the breaker size, simply divide the adjusted wattage by 240 volts to find the rated amperage needed for your subpanel. Often, the result is not a common circuit breaker size. and you can simply round up to the next higher size of the breaker.

## How many outlets can be on a 15 amp circuit?

eight lightsTypically, you can have no more than eight lights or electrical outlets on a 15-amp circuit.
