Recommendation Lighting Circuit Cable

This type of wiring system does away with the need for junction boxes and separate cables to the lights.

Lighting circuit cable. All the necessary connections are made within the rose. Unlike the ring power circuit the lighting circuit does not form a loop returning to the consumer unit. All seems ok except for the lighting circuit.

There s a separate terminal in the rose for the switch cable neutral core which passes current directly to the live core of the pendant flex. The three conductors are laid side by side within a pvc. If you have longer lengths to cover 1 5mm squared cable can be used and the maximum length allowed using this is 110m.

Three core and earth cable. This is the standard format that will be used for the vast majority of your lighting circuit. With loop in wiring the main circuit cable from the consumer unit loops in and out of multi terminal ceiling roses from which individual cables run to the light switches.

In all lighting circuits a ground cable must be installed. It consists of a red insulated core for live black insulated core for neutral with a bare earth conductor between them. Each of the cores except the earth is covered in a layer of colour coded pvc insulation to allow identification these cores are then covered in an outer layer of pvc known as the sheath.

This type of cable is used for wiring two way light switches. This does not include the light switches which should be wired in switch wire which contains 2 red cores. Landing lights with a switch upstairs and down or intermediate switching the cable format below may be used.

The device is grounded. Using 1mm cable is allowed for up to 95meters of circuit length. Old colour twin and earth lighting circuit cable 3 core and earth cable if you have two way switching e g.
