Radial Lighting Circuit Wiring Diagram. You may find this wiring arrangement in older properties. This would be cable a in the diagram below fig 2 which shows how the ceiling rose is terminated.
Radial lighting circuit wiring diagram 3 way switching from junction box light circuit wiring diagram. It shows the components of the circuit as simplified shapes and the skill and signal associates in the middle of the devices. Old multi point radial lighting diagram using junction boxes fig 1 shows what is referred to as a radial circuit sometimes called a loop in or multi point radial lighting circuit.
Loop in as per diagram above.
The radial lighting circuit has 3 common wiring options which may be mixed at will. So before we get stuck in to some wiring diagrams. Radial or junction box wiring picture 2 below shows a typical radial or junction box lighting system a two core and earth cable runs from the consumer unit to a series of junction boxes one for each lighting point ceiling rose. The circuit is fed to each lamp fitting in turn and a separate cable connects from the fitting to the switch.
