Electric Cable For Lighting Circuits

A lighting circuit can serve up to 12 x 100w bulbs.

Electric cable for lighting circuits. Electrical cable is in any building requiring electricity for the lighting and power. Type two lighting circuit. What size cables for lighting circuits. Introduction to lighting circuits.

There are many types of cable used to keep a building running choosing the right type and size of cable for the job is critical. This does not include the light switches which should be wired in switch wire which contains 2 red cores. The consumer unit is normally connected to the first lamp which in turn is connected to the second lamp and so on. The reason why the wiring of a lighting circuit is more complex than a power circuit is that each outlet or light fitting needs to be controlled by a separate switch.

Cable will be used for lighting. The first thing to do is to run a length of cable from the supply distribution board to the light itself. The cable sizes for domestic lighting circuits is usually 1mm or 1 5mm twin and earth cable aka two core and earth. Electrical wiring in the united kingdom is commonly understood to be an electrical installation for operation by end users within domestic commercial industrial and other buildings and also in special installations and locations such as marinas or caravan parks.

In most cases 1mm should be fine but depends on how many lights are on the circuit and how long the cable run is. One way of providing for this is to install a four terminal junction box in which the cable from a light and the cable from its switch can be connected to the circuit cable. Unlike the ring power circuit the lighting circuit does not form a loop returning to the consumer unit. Phase neutral and ground all three conductors reach to the terminal point of each luminaire and if it has a metal chassis the ground should be connected in the appropriate position.

Light pendants are mostly used in domestic environments but the principle of wiring is similar to all types of light fittings. It does not normally cover the transmission or distribution of electricity to them.
