How To Wire A Lighting Circuit In A House

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

How to wire a lighting circuit in a house. You must use the brown slewing to indicate the switched line wire. The circuit is fed to each lamp fitting in turn and a separate cable connects from the fitting to the switch. Once you have mastered the basics. Loop in as per diagram above.

To wire this circuit 2 wire cable runs from the dimmer to the light. This does not include the light switches which should be wired in switch wire which contains 2 red cores. Once connected the light pendant should look like this click to enlarge. Here you can see there is a cut in the line wire connected to lamp 3 so the bulb is switch off and the rest circuit is working.

The other wire from the dimmer is spliced to the black cable wire which runs on to the hot terminal on the light. Without it the blue wire indicates a neutral wire. Once you have read the safety tips a good place to start is by getting up to speed on the basic radial lighting circuit. To wire a light in your home start by switching the appropriate circuit in your fuse box to off so you can work safely with the wires.

The radial lighting circuit has 3 common wiring options which may be mixed at will. Next twist together like colored wires coming from the fixture and the wall or ceiling such as black with black and red with red then screw a wiring cap over the exposed ends. Push the long wire through the hole in the top of the special green wire connector and connect the remaining wires to it by twisting the connector clockwise until it s tight. Leave one bare ground wire long and snip the rest to 6 in.

Once you know this every other lighting circuit will be easy to wire because the principles are the same. Fold the ground wires neatly into the back of the box photo 11. 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. Another major defect of series lighting circuit is that as all lamps or bulbs are connected between line l and neutral n accordingly if one of the light bulb gets faulty the rest of the circuit will not work as the circuit will be open as shown in fig below.

Lighting circuits typical lighting circuits are designed as 15 amp 120 volt or 20 amp 120 volt. Using 1mm cable is allowed for up to 95meters of circuit length. If you have longer lengths to cover 1 5mm squared cable can be used and the maximum length allowed using this is 110m. Planning the electrical circuits for a home will depend on a few factors such as the location or area of the home where the circuits will be installed and the devices that will be connected to the circuit.

The source is at the dimmer and the hot wire is spliced to one hot wire on the device.
