Any electrical works must always comply with current Electrical Regulations.
When fitting or have the installation of a new electric hob or cooker it must be connected to its very own circuit having its own fuse or circuit breaker. It is not acceptable to spur this appliance from another circuit.
For a new installation will mean a new circuit, a Part P qualified competent electrician can only carry out this work. A separate cooker cable must be connected to the mains from the cooker and the correct fuse incorporated.
An electric cooker demands a considerable amount of power and current due to the amount of heat they have to generate. For this reason a thicker cable is required along with a larger than normal fuse and a double pole isolation switch.
Double pole switch
A normal switch breaks the power in a live wire in the circuit turning something off and breaking the connection. A double pole switch also breaks the neutral connection along with the live connection reducing and worries of a residual current being present that may cause a shock when the switch is in the off position.
As a cooker is wired to its very own circuit the power supplying the cooker comes directly from the main consumer unit running through the switch. Due to the high level of current a cooker demands it is not necessary to run another cable back to the consumer unit to form a ring main. This means the cooker circuit is called a radial circuit.
Cooker control switch
A cooker control switch is the cookers main isolator and must be connected to the cooker. Depending on the power of the cooker will determine the size of cable required. The cooker control switch is on the wall flush and held inside a patress box very much like a switch or a socket.
Cooker control switches can incorporate a 13-amp socket and others can be just for your cooker. Some have red neon lights to show the cooker control switch is on or off. If a 13-amp socket is incorporated then an additional 5-amps will need to be taken into consideration in the circuit when installing switches and cables.
Terminal outlet cover plate
The cooker control switch is usually situated above the worktop next to the cooker to one side so to make it easy to turn it off or on and have to stretch over the cooker.
Once the cable is in the cooker control switch you can strip the cable insulation back preparing the cable ends. There are two sets of terminals and connections inside the cooker control switch. Incoming mains must be connected to the incoming terminal marked as mains and the outgoing cable must be connect to the outgoing terminal marked as load.
The load cable is connected to the terminal outlet usually situated behind the cooker and held inside a patress box on the wall very much like a switch or a socket. It acts as a junction box for the cooker cable to be connected to mains power.
A plate covers over the terminal outlet keeping the wiring covered for safety but allowing simple access when required. Once all connections have been completed the cable can be connected to the mains power ensuring the correct fuse is being used.
