More electricity needed by a cooker requires a thicker cable than for a table lamp.
I assume you mean a cooker switch, which should be fed from a 40A MCB in the conmsumer unit and with 6mm cable
An electric cooker cable is designed to handle higher power loads and is typically thicker and more robust compared to a bulb cable which is thinner and designed for lower power applications like lighting. Additionally, an electric cooker cable may have different connectors and insulation ratings as it is meant for higher temperature environments.
To answer this question the voltage of the cooker is needed.
6 mm twin and earth
To join the pair of cable trays.
The voltage is always determined by the device. (in this case a slow cooker).However, having established what voltage to supply to the device, the cable must be suitable for the voltage used. Everything in the chain of power transmission, must be rated for the correct voltage. Cables, plugs, fuses etc.
For a cooker oven with a maximum of 2600 watts, a 2.5mm cable is recommended to handle the load safely. This size of cable is commonly used for appliances with this power rating and will ensure that the electrical supply is properly distributed without overheating the cable. Be sure to consult a qualified electrician for installation to ensure safety and compliance with wiring regulations.
A cable joint is where multiple cable join together! Here's an XLPE cable joint(for other types of cable theres an other type of joint example: for a steel cable for bridges theres an iron/steel joint):
Red - active, (commonly known as your live cable) Black - Neutral Green - Earth
It is located on the side of the engine where the cruise/accelerator cable and A/T kickdown cable all join together.
The largest size of twin and earth cable available is typically 16mm² in the UK market. This size is commonly used for higher current applications such as cooker circuits or shower circuits.
