Please also check the rules very carefully for ring mains and radial circuits. If a cartridge fuse is used it should be rated at 5amps if an mcb is used it should be rated at 6amps. These diagrams show various methods of one two and multiple way switching. First let s have a look at this wiring diagram describing a lighting circuit in its most basic form. We have and extensive collection of common lighting arrangements with detailed lighting circuit diagrams light wiring diagrams and a breakdown of all the components used in lighting circuits. Unlike the ring power circuit the lighting circuit does not form a loop returning to the consumer unit. It is also a requirement that all connected appliances must be individually fused usually within the 13a plug. The consumer unit is normally connected to the first lamp which in turn is connected to the second lamp and so on. Lighting circuits with fluorescent tubes. The cable used is a 1sq mm pvc twin core and earth rated for up to 12 amps.
It consists of a red insulated core for live black insulated core for neutral.
We have and extensive collection of common lighting arrangements with detailed lighting circuit diagrams light wiring diagrams and a breakdown of all the components used in lighting circuits. The ring circuit is made up of two radial circuits connected to the same series of accessories within the circuit. Please also check the rules very carefully for ring mains and radial circuits. The most basic circuit with only two wires at the switch. However in this guide we ll focus on the lighting circuit. Two way switching 2 wires.
You are limited in the length of cable you are allowed to use in both circuits. Go to back to content 5. All the light wiring diagrams are available in the old and the new cable colours to avoid confusion. Circuit of a 40w fluorescent tube with 40w ballast and starter. Two way switching 2 wires. It allows the appliance to be switched. Switching lighting circuit operating diagram. To avoid the house being in total darkness if a fuse should blow or trip lighting circuits are split into upstairs and downstairs. Earth wires are not shown. It consists of a red insulated core for live black insulated core for neutral.
If a cartridge fuse is used it should be rated at 5amps if an mcb is used it should be rated at 6amps. Using a ring or radial circuit to power lighting requires the use of a fused spur which is fused independently of the circuit the power is coming from. This is usually a distribution board of some sort. Supply switch and light. The ring circuit is made up of two radial circuits connected to the same series of accessories within the circuit. You are limited in the length of cable you are allowed to use in both circuits. Circuit with two fluorescent tubes 20w each with 40w ballast and two starters 20w each the fluorescent tubes are used particularly in factories offices for decoration and advertising or. To avoid the house being in total darkness if a fuse should blow or trip lighting circuits are split into upstairs and downstairs. The ring starts at the consumer unit also known as fuse box distribution board or breaker box visits each socket in turn and then returns to the consumer unit. Switching lighting circuit operating diagram.
You can see more about how a switched or fixed fused spur works in our project here. Circuit of a 40w fluorescent tube with 40w ballast and starter. It is also a requirement that all connected appliances must be individually fused usually within the 13a plug. The ring starts at the consumer unit also known as fuse box distribution board or breaker box visits each socket in turn and then returns to the consumer unit. This is usually a distribution board of some sort. The ring is fed from a fuse or circuit breaker in the consumer unit. The consumer unit is normally connected to the first lamp which in turn is connected to the second lamp and so on. In order to energise the light we need to connect it to the supply available. So before we get stuck in to some wiring diagrams start here to make sure you keep yourself safe. Unlike the ring power circuit the lighting circuit does not form a loop returning to the consumer unit.
The cable used is a 1sq mm pvc twin core and earth rated for up to 12 amps. Switches are shown as dotted rectangles. Using a ring or radial circuit to power lighting requires the use of a fused spur which is fused independently of the circuit the power is coming from. We have and extensive collection of common lighting arrangements with detailed lighting circuit diagrams light wiring diagrams and a breakdown of all the components used in lighting circuits. You are limited in the length of cable you are allowed to use in both circuits. This arrangement would typically be used in conduit and uses two wires. This arrangement allows the use of conductors with smaller cross sectional areas compared to a regular radial circuit arrangement. Lighting circuits with fluorescent tubes. Switching lighting circuit operating diagram. It is also a requirement that all connected appliances must be individually fused usually within the 13a plug.
The ring circuit is made up of two radial circuits connected to the same series of accessories within the circuit. The consumer unit is normally connected to the first lamp which in turn is connected to the second lamp and so on. Unlike the ring power circuit the lighting circuit does not form a loop returning to the consumer unit. Circuit with two fluorescent tubes 20w each with 40w ballast and two starters 20w each the fluorescent tubes are used particularly in factories offices for decoration and advertising or. A switched fused spur is also used when connecting a cooker hob dishwasher washing machine or fridge to the circuit. Switching lighting circuit operating diagram. This arrangement would typically be used in conduit and uses two wires. The ring is fed from a fuse or circuit breaker in the consumer unit. All the light wiring diagrams are available in the old and the new cable colours to avoid confusion. The ring starts at the consumer unit also known as fuse box distribution board or breaker box visits each socket in turn and then returns to the consumer unit.
