Neat Household Lighting Circuit

You can also see that another live and neutral wire go to the next.

Household lighting circuit. As you can see a basic lighting circuit consists only of three components. Duplex gfci 15 20 30 and 50amp receptacles. Once you have read the safety tips a good place to start is by getting up to speed on the basic radial lighting circuit.

The live feed from the consumer unit fuse board. Sometimes called a loop in circuit this shows how power is distributed around the lighting circuit via the ceiling roses or junction boxes and how to wire a light switch into the circuit. This is where you can control the same light via two switches.

This is usually a distribution board of some sort. Multi point radial lighting circuit old cable colours fig 1. Unlike power circuits lighting circuits are always of the radial type.

If your lighting circuit has all the cables terminate in ceiling roses rather than junction boxes please refer to one of the following instead. To avoid the house being in total darkness if a fuse should blow or trip lighting circuits are split into upstairs and downstairs. However in this guide we ll focus on the lighting circuit wiring.

Please also check the rules very carefully for ring mains and radial circuits. The neutrals are connected together using a terminal connector. The cable leaves the consumer unit and runs to each outlet position before terminating at the last fitting on the line.

Once you have mastered the basics we take a look at the two way switch arrangement. You are limited in the length of cable you are allowed to use in both circuits and long spurs could make you exceed the limit. Instead of taking the feed wire from the consumer unit to the ceiling rose it is taken to the switch.
