How to Safely Plug Electrical Appliances: 3 Core Cable, Fuse Sizes, and Wiring Colors Explained for Kids
Poppy Taylor robshaw
@poppytr4949
Wiring and Electrical Safety
Proper wiring is crucial for electrical safety. Each wire in a three-core cable has a specific function and must be connected correctly:
- The blue wire, known as the neutral wire, carries current out of the appliance and connects to the left terminal in the plug.
- The brown wire, called the live wire, brings current into the appliance and connects to the right terminal in the plug.
- The green and yellow wire, referred to as the earth wire, is a safety feature that directs excess current to the ground.
Highlight: Always remember the 3 core and earth cable colours: Brown for live, blue for neutral, and green/yellow for earth.
The fuse is a crucial safety component positioned between the live pin and live terminal. It has a low melting point to prevent fires by interrupting the circuit if too much current flows.
Definition: Mains electricity is the power generated by power stations and distributed through the National Grid. In the UK, it operates as an alternating current with a frequency of 50Hz and a potential difference of about 230V.
Example: When choosing a fuse for your appliance, consider its power rating. For most small kitchen appliances, a 3 amp fuse is suitable, while larger appliances may require a 13 amp fuse.
Understanding these concepts is essential for safely using electrical appliances in your home, especially in areas like the kitchen where multiple devices are often used simultaneously.
Understanding Plugs and Electrical Safety
Plugs are essential components that allow electrical appliances to be safely connected to power sockets. They consist of several key parts, each serving a specific purpose in ensuring safe electrical usage.
Definition: A plug is a device that allows electrical appliances to be safely connected to a power socket.
The three-core electrical cable is a crucial element of a plug, providing a safe passage for electricity. It contains three wires, each with a specific function:
- Live wire : Carries current into the appliance
- Neutral wire : Carries current out of the appliance
- Earth wire : Provides a safety path for excess current
Highlight: Understanding the function of each wire is crucial for safely plugging electrical appliances in kitchen and other areas of the home.
The fuse is another critical component of a plug, designed to "blow" if too much current passes through it. This safety feature helps prevent electrical fires and damage to appliances.
Vocabulary: A conductor is a material that allows charge to move easily through it, such as copper wire. An insulator, on the other hand, is a material that doesn't allow heat or charge to move through it easily, like rubber.
The plug also features a cable grip that keeps the wires securely in place, ensuring a stable connection and preventing accidental disconnection.
Example: When wiring a plug, always ensure the live, neutral and earth wires are connected to the correct terminals. The live wire goes to the right, the neutral wire to the left, and the earth wire to the top.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
