Lighting Circuits Explained
Each house should ideally have at least two lighting circuits.
Lighting circuits explained. Examples of the wiring found at ceiling roses on radial junction box installations are given on this page radial circuits. These days the loop in system predominates though individual circuits often combine the two for the most economical use of cable. The live is interrupted by the switch wiring and the circuit is carried on to the next junction box. Whilst this system is rarely used now it is much less complicated for the consumer to connect new light fittings.
A cable is run from the junction box to the light usually via a ceiling rose. All type of light switches explained. Lighting circuits are wired in two different ways using either junction boxes or loop in ceiling roses. The second system in popular use is the junction box circuit or system.
Type one lighting circuit. 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. Basics of uk lighting circuits connections to ceiling rose and light switch. Each protected by a 5 amp fuse or 6 amp trip in the consumer unit.
How to wire a light. Unlike power circuits lighting circuits are always of the. Series parallel circuits explained. The requirements of a lighting application often dictate what type of circuit can be used but if given the choice the most efficient way to run high power leds is using a series circuit with a constant current led driver.
All types of lighting circuits in old and new cable colours. Radial circuits are used for lighting there is one lighting circuit on each lighting mcb lighting circuits are usually on a 6a mcb or 5a fuse though 10a can be used with some extra restrictions now removed in the 17th edition of the wiring regs for large circuits however if the area served is large more 5a or 6a circuits would in most cases be preferable.
