Trying to wire in a light outside for a one way switch but the cable is 3 core and earth brown black Grey copper and the light only has 3 terminals L N and E.

We hope that this outline of wiring colour codes helps you out in your home or business. This cable consists of three cores – brown grey and black which are all Line colours and an Earth wire. Blue was Neutral so Grey is Neutral with Blue sleeve.

Cable D Fig 2 is a three core and earth this is the 3 wire control that links the two light switches together. Standard 2-core and earth 6242Y PVCPVC cabling can be used for the initial mains feed to one of the alarms in the circuit with the subsequent connections between the alarms having an additional Interconnect connection along with the Live Neutral and Earth connections. These colours are strongly advised but not mandatory.

Corewire that provides a connection to earth for safety and protection purposes for both end-user devices and metal objects and components in the installation. For wiring a two way switch 3 CoreEarth cable is used. If you are finding cables being marked its because they used the wrong cable and had to identify the ends.

And of course sleeving. For example any three-core 3CE or four-core 4CE power cable bought in Australia would follow the above colour codes. 3-core and earth 6243Y PVCPVC cabling can be used for interconnect cabling.

Standard 3 core and earth cable is sized. Black – Earth Sleeved green yellow AFAIK there is no regulation requiring the above colour coding I believe that it would be compliant to use the black core for neutral sleeved blue and to use the grey core for earth sleeved greenyellow. Before this change old wiring colours in the UK for 2-core wire were red live black neutral and earths are either bare or yellow and green whereas with 3-core cable live red blue neutral additional yellow and earth either bare or yellow and green.

Regional wiring colours may differ from those represented here. Phase 1 Brown Phase 2 Black Phase 3 Grey Neutral Blue Earth GreenYellow. I think earlier versions may have had white instead of yellow but thats going back to the early days of PVC cable.

The original light has a switch inside so the PIR can be overridden. Post March 2004 the UK standard was changed to Grey Black and Brown with a bare copper earth. Fantasia Ceiling Fans are sold as DIY products.

For installations using a double wall control 3 core and earth wiring is required. Red White dark Blue. This cable consists of three cores brown grey and black which are all Line colours and an Earth wire.

Wiring a three-way switch happens with the use of the 3 CoreEarth cable. 3 way light switching new cable colours 3 way light switch old cable colours. Connect the Line brown wire coming from the light together with the 3 CoreEarth cable black wire in to the L1 terminal of the two-way switch.

Twin and earth wiring is required for all installations except those using a double wall control. For three phase wiring our standard colours are. The earth core in the cable is normally just bare copper during installation this needs to be inserted through a Green and Yellow sleeve where the earth is connected to a fitting or appliance.

Due to the colours of 3 core cable brown grey and black certain conductors will need an appropriate blue or brown sleeve over them to denote their use within the circuit see diagrams below. Old multi-point radial lighting diagram using junction boxes. Fantasia ceiling fans run on standard lighting wiring.

COM on the first switch connects to COM on the second switch L1 on the first switch connects to L1 on the second and L2 on the first switch connects to L2 on the second. Phase 3 Yellow Neutral Grey Earth Green Greenyellow or bare Europe. 2 way light switch 3 wire system new harmonised cable colours 2 way switch 3 wire system old cable colours 2 way switch two wire control Three way switching.

We always used yellow for earth if using 3 core SWA for single phase so now use Black with GY sleeve. In my experience it was always Red Blue Yellow. Active Brown Neutral Blue Earth GreenYellow Multiphase.

Pre March 2004 the UK standard for 3 core and earth cable used in two way lighting was blue yellow and red with a bare copper earth. Connect the Line brown wire coming from the light together with the 3 CoreEarth cable black wire in. If you want a LNE cable it should be Brown Blue GY.

We recommend using the brown cable for the permanent live L the grey cable sleeved blue for the neutral N and the black cable sleeved brown for the switch-live SL. If you have a 3 core cable with Brown Black Grey its a 3 Phase cable ie no neutral. Colour-coded greenyellow striped may be bare within sheathed cablepre-2004.
