Fine Beautiful Electrical Lighting Circuit
Once you have mastered the basics we take a look at the two way switch arrangement.
Electrical lighting circuit. Electrical lines which include lighting circuits begin from the main distribution panel of the installation and each line contains three conductors. A single 5 6 amp circuit can cope with up to twelve 100 watt lamps it is usual in a multi storey house to have at least one lighting circuit for each floor even if the number of lamps are less than 12 on each level. Introduction to lighting circuits.
Each house should ideally have at least two lighting circuits. A lighting circuit can serve up to 12 x 100w bulbs. The cable leaves the consumer unit and.
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. Supply switch and light. Each protected by a 5 amp fuse or 6 amp trip in the consumer unit.
In modern domestic properties in the uk the main electric lighting circuits are separate from the power ring main circuit. The l line also known as live or phase is connected to the first lamp and other lamps are connected through middle wire and the last one wire as n neutral connected to the supply voltage then. Two way switching 2 wires.
Earth wires are not shown. This is usually a distribution board of some sort. L and n indicate the supply.
Phase neutral and ground. These diagrams show various methods of one two and multiple way switching. If you have longer lengths to cover 1 5mm squared cable can be used and the maximum length allowed using this is 110m.
