What amp fuse should I use?
If it’s a rewireable type plug and the original fuse size fitted by the manufacturer is not known, the recommended method is to use the 700W rule: For an appliance rated as 700W or less, a 3A fuse should be fitted. For appliances above 700W, a 13A fuse should be fitted.
How many watts can a 3 amp fuse take?
700 watts
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 many watts can a 10 amp fuse take?
2300 Watts = 10.00 Amp.
What amp fuse do I need for a vacuum cleaner?
A typical example is a vacuum cleaner that may be rated at less than 700W, but will require a 13A fuse to prevent the fuse from blowing when first switched on. BS1363 has standardised on just two preferred fuse ratings, 3A and 13A, however any fuse rating up to 13A can still be used.
Can you use a 3 amp fuse in a 13amp plug?
Yes of course there is. The cable or flex attached to the gas fire is purely to supply the ignition. The flex provided is not rated to 13A because the ignition requires very little current and so the flex requires protection by a 3A fuse.
How to select the right fuse for a control circuit?
This mistake can lead to compromised system integrity—impacting personnel and equipment safety. Find the right control circuit or supplemental fuse in three simple steps: Select the fuse type. Select from time-delay fuses for inductive loads or fast-acting fuses for resistive loads. Select the voltage rating required.
Why do you need a fuse on a PCB?
Fuses are ideal to protect wires and printed-circuit-board (PCB) traces from melting and fire. This can happen when shorts develop from abraded wires or magnet wire getting shorted from vibration and constriction due to ac magnetic fields. Another common failure is from electrolytic and tantalum capacitors, which can fail in a short-circuit.
How to choose a fuse for an overcurrent protective device?
Select the fuse type. Select from time-delay fuses for inductive loads or fast-acting fuses for resistive loads. Select the voltage rating required. The voltage rating must be equal to or greater than the circuit voltage for the proper application of an overcurrent protective device.
Why do you need to know about fuse selection?
Through proper fuse selection, you can minimize risks and failures so that an electronic product retains its competitive edge. Fuses are overcurrent devices that protect electrical and electronic devices by melting and opening a circuit to prevent excessive current from causing damage or starting fires. Fuses serve two main purposes:
