# Question: What Amp Fuse Do I Need?

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

As others have said, your LED lights will draw little amperage so based solely on the lights being used in these circuits, you could probably get away with 5 amp fuses.

This is correct.

The fuse is there to protect the wire in the event of a short circuit, not there to protect the devices connected to the circuit..

## What happens if you use the wrong amp fuse?

Fuses are present to protect the components of the electrical system. Rather than destroying the circuit when there is a surge of power, the fuse blows to protect it. … If you use a fuse with the wrong amperage, the fuse won’t blow as intended, damaging the circuit and resulting in a much larger repair bill.

## 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.

## Can I use a 13 amp fuse instead of a 10 amp?

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.

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

Fuse rating = (watts/volts) x 1.25 Say the calculated fuse rating is 2.2679 amps, use a 3 amp fuse. Say the calculated fuse rating is 4.9431 amps, use a 5 amp fuse.

## What are 5 amp fuses used for?

Some circuits in older houses might contain Fuse Wire instead of Fuses. If this is the case in your house, you should use 5 amp wire for a lighting circuit, 15 amp for an immersion heater circuit, 30 amp wire for a ring main or cooker circuit (for cookers up to 12 kw).

## What FUSE do I need for 12v?

There are 3 types of 12v fuses I recommend. They are Spade Fuses, ANL fuses, and Re-settable Breakers. Spade fuses are the fuses that you’ll commonly find in your car’s fuse panel and are typically for items run out of your distribution block and less than 30 amps (in our case.

## What appliances need a 5 fuse?

Domestic Appliances Fuse Ratings Coffee maker – 5 amp. Dishwasher – 13 amp. DVD player – 3 amp. Electric blanket – 3 amp.

## How do I choose the right fuse?

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).

## Can I use a 5 amp fuse instead of a 3 amp?

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 many watts can a 5 amp fuse handle?

1150 WattsMultiply the voltage by the amps and this will give you the maximum number of Watts you can place on the circuit. 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.

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

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.
