What is BS1362 fuse?
BS 1362 is the British Standard number for cartridge fuse links used in UK plug tops. BS1362 fuses protect the cables connected to domestic equipment against overloads or small overcurrents. They may also be used in appropriate single-phase installations (for example, fused spur connection units).
How many amps can a 13A fuse take?
Fig 1 BS1362 fuse characteristics. It may not be immediately apparent, but a 13A rated fuse is not designed to actually blow at 13A. In fact a 13A fuse will allow a current of 20A to pass indefinitely without blowing.
What does 13A mean on a fuse?
13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.
Is 13A and 3A fuses the same?
A 3A fuse is the safest to use and should be used for appliances at 700w or less. Appliances rated above 700w should use a 13A fuse. Be extra cautious when using a 13A fuse and try using a 3A fuse if and when it’s possible.
What fuse do I need for a fridge freezer?
3 amp fuse
Some appliances, such as lamps, televisions, computers, fridges and freezers generally require a 3 amp fuse.
Can you put a 20 amp fuse in a 13 amp plug?
A 20A fuse in a domestic 13A plug should never be used.
Can I put a bigger fuse in my amp?
Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components. A blown fuse indicates excessive current has entered the circuit.
Can I replace a 13A fuse with a 3A?
The 13A fuse is on the plug. The power rating is so low that we can quickly see that the fuse is too high and needs to be changed to a 3A one.
Can I use a 13 amp fuse for a freezer?
Are you overloading your electrical sockets? Some appliances, such as lamps, televisions, computers, fridges and freezers generally require a 3 amp fuse. However washing machines, dishwashers, microwaves, kettles, toasters and irons usually require 13 amp fuses.
Why does my fridge keep blowing a fuse?
Your fridge’s fuse can blow due to any the following reasons: A power surge causes a temporary increase in the electricity travelling through the circuit. Some fuses are designed to withstand short bursts of high electricity, while others are not. Overtime, the fuse itself may simply weaken.
Can I replace a 13 amp fuse with a 5 amp?
You are mistaken. If 13A is the maximum allowable, then it could well be the case that the normal operation of your heater is > 5A, which would blow your 5A fuse immediately. It’s not safe to operate a heater without the appropriate fuse.
How do you check to see if a fuse is blown?
Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
What is a BS1362 fuse used for?
BS 1362 is the British Standard number for cartridge fuse links used in UK plug tops. BS1362 fuses protect the cables connected to domestic equipment against overloads or small overcurrents. They may also be used in appropriate single-phase installations (for example, fused spur connection units).
What is the power dissipation of a 13A fuse?
BS 1362, the British Standard for plug fuses, specifies a maximum power dissipation of one watt when carrying the rated current. The actual current, where a BS 1362 fuse will blow, is about 1.66 times the rated value, so for a 13A fuse this will be 21.6A.
What is the actual current of a 1362 fuse?
The actual current, where a BS 1362 fuse will blow, is about 1.66 times the rated value, so for a 13A fuse this will be 21.6A. Fig 2 Damage to plug caused by overloading.
What is the size of a 13 amp plug top fuse?
13 Amp / 13A plug top fuse (the highest rating fuse that can be fitted to a UK plug top), made to the British Standard BS1362. Dimensions : length 25.4mm (1 inch), diameter 6.3mm (1/4 inch).
