IET Forums 13A fuse in 3A socket. yes but we only protect against a short circuit on the appliance, not normally a minor overload, a short circuit will remove any fuse or none, the overload will be handled at the appliance end of the cable which is the European approach with unfused sockets.
Is the 13A fuse the same as the 3A?
For a 700W unit or less, a 3A fuse must be installed. For devices over 700 W, a 13 A fuse must be installed. … A typical example is a vacuum cleaner with a rating of less than 700W, but which requires a 13A fuse to prevent the fuse from blowing the first time it is switched on.
What happens if you use the wrong fuse in an outlet?
Fuses are provided to protect the electrical system components. Instead of destroying the circuit in the event of a power surge, the fuse blows to protect it. …If you use an incorrect amperage fuse, the fuse will not blow as expected, damaging the circuit and causing a much higher repair bill.
Can you put a 3 amp fuse in a 13 amp fusible switch?
Yes you can . The merged leg merges into phase only and when switched, only changes phase.
What happens if I put a 13A fuse in a 5A socket?
Re: Can I use a 13A fuse in a 5A socket? no You must use a 5A fuse. Using a 13A fuse creates a fire hazard.
What happens when you put a top fuse in an outlet?
Replacing a fuse with a larger one will work, but will create a dangerous circuit. This could cause the equipment to fail, burn, or cause a fire. The fuse is designed as a safety device. It should not only be the right amperage, but also the right voltage and blow fast or slow.
What happens when you replace a fuse with a higher amperage fuse?
Replacing a fuse with a higher amperage fuse is a very bad idea and can cause fires. Fuses (and circuit breakers) are rated to blow or trip before any part of the circuit reaches dangerous currents.
Can I use a 13A fuse in a 3A socket?
No, it won’t. The only difference would be the current flowing under fault conditions. If the OP changes his lamp cord to a size that will withstand at least 13A under normal/faulty conditions, he could leave that 13A fuse in place until removed!
Does the fuse you plug into an outlet matter?
The device itself is equipped with a fuse to help protect the device. A power cable’s fuse should only be smaller than the maximum current capacity of the cable. So if you use a 20 amp cable, a 13 amp fuse will protect it.
Can I put a 3A fuse on a 13A fused branch?
Yes you can . The merged leg merges into phase only and when switched, only changes phase. 5
Is a 3A fuse the same as a 13A fuse?
A 3A fuse must be installed for a device rated at 700W or less. For devices over 700 W, a 13 A fuse must be installed. … BS1363 has only standardized two preferred fuse ratings, 3A and 13A, but any fuse rating up to 13A can still be used.
What devices use a 3A fuse?
Different types of fuses The plugs of devices with a maximum power of about 700 watts must be equipped with a 3 ampere fuse (red color). For example: 3A fuse – table lamp, floor lamp, TV, video, computer, blender, blender, refrigerator, freezer, electric drill, jigsaw, soldering iron.
Can I put a 3A fuse in a 10A socket?
A 10 amp fuse for a TV is overkill. Most TVs have a 2 or 3 amp fuse inside. Installing a 13A fuse in a 10A circuit can cause an overload or fire. Install the correct size fuse.
