Frequently Asked Questions (FAQs)
1. What are plug fuses for?
Plug fuses are safety devices designed to protect the electrical lead rather than the appliance itself. They act as deliberate weak links in a circuit and will 'blow' if an appliance or extension lead draws too much current due to an overload or fault, preventing damage or fire hazards.
2. What are the two types of plug fuses?
The two types of plug fuses commonly used are Type-SL and Type-TL fuses. These are medium-duty time-delay fuses. The only difference between them is the type of base they have: SL fuses have a rejection base, while TL fuses have an Edison base.
3. Does it matter what fuse you put in a plug?
Yes, it is crucial to use the correct fuse rating for a plug. The fuse rating should be compatible with the power rating of the device it is attached to. Most UK plugs are fitted with a 3 amp or 13 amp fuse, depending on the power requirements of the device.
4. How do you tell if a plug needs a new fuse?
To determine if a plug needs a new fuse, remove the fuse from its holder and inspect the fuse wire. If there is a visible gap in the wire or a dark/metallic smear inside the glass, the fuse is blown and needs to be replaced.
5. Will a plug work without a fuse?
No, a plug will not work without a fuse. The fuse plays a crucial role in protecting the circuit and the appliance from damage caused by excessive current. Without a fuse, the circuit would be at risk of overloading and potentially causing fires or damaging the electrical system.
6. How do I know what fuse my plug takes?
To determine the correct fuse for a plug, check the power rating of the appliance. The power rating is usually indicated on a sticker, printed, or embossed directly on the appliance. Match the power rating to the appropriate fuse. However, it is essential to consult the manufacturer's guidelines as there may be exceptions for certain appliances.
7. What happens if I put the wrong fuse in a plug?
Using the wrong fuse in a plug can have serious consequences. If the fuse rating is too high, it may not blow as intended during an overload or fault, potentially damaging the circuit or causing a fire hazard. It is crucial to use the correct fuse rating to ensure the safety and proper functioning of the electrical system.
