Question: What Amp Fuse Do I Need?

Do I need an inline fuse for LED lights?

These LED lights draw less amps than your standard incandescent lights.

You should not need a circuit breaker of in line fuse.

However, you can install an inline fuse if you feel that you need one..

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.

Can I use a 15 amp fuse instead of a 10 amp fuse?

Yes, the 15 Amp fuse may be sized for a device in that particular circuit, and the 10 Amp fuse may be very short lived.

How do I choose a motor fuse?

Motors should be fused with a time-delay fuse rated 175% of the motor’s full load operating amperage, 250% of the full load operating amperage if a circuit breaker is used. The wire to a motor must be rated to carry 25% more amperage than the motor draws when operating at full load.

What is a 5 amp fuse used for?

Domestic Appliances Fuse Ratings Coffee maker – 5 amp.

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 do I know what amp 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 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.

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

You should use at least a 100A fuse. The fuse at the batt. is to protect the power wire.

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.

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.

Is using a higher amp fuse bad?

In general, NO. Replacing a fuse with a higher-amp fuse is a very bad idea and can lead to fires. Fuses (and circuit breakers) are rated such that they blow or trip before any part of the circuit gets to a dangerous current. … Fix the underlying problem, and you won’t have any more blown fuses.

What kind of 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.

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.

What size fuse should I use?

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.

What is 3 amp fuse 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.
