This is a form of parallel wiring that has one cable usually twin and earth 6242y containing the live neutral and earth wires looping in and then out of leach light fitting. The loop in wiring system is straight forwards but has the disadvantage of making it difficult to replace the ceiling rose for a more modern style light fitting.

Loop in loop out wiring diagram. Line diagram of a one way lighting circuit using loop in ceiling roses fig 1. This diagram shows how the power is fed from the consumer unit to the first light and then to each consecutive light on the circuit hence it is named the circuit wire. Picture 1 shows the basic principle of wiring a loop in lighting system the most moderncommon. The principle is exactly the same as when looping at the ceiling rose or using a junction box. Every instrument in a loop drawing has an input calibration and an output calibration specified for the instrument. The favoured way of wiring recessed downlights is using the loop in loop out method.
The switch connects between the loop and live terminals so the live terminal is only live when the switch is on. Lighting circuits loop at the switch. This is a typical wiring diagram of a loop powered signal isolator get energy from the input and 4 wire transmitter detailed parameters of loop powered signal isolator ato s sinir 502e are in the product page. Cable numbers wire colours junction block numbers panel identification and grounding points are all shown in loop diagrams. Wiring diagram of loop powered isolator with external powered 4 wire transmitter. One cable lne either from the mains board or the last ceiling rose one cable lne out to the next ceiling rose and one cable lsl e that goes to the wall or pull switch within that room.
The in cable supplies power from the previous light or consumer unit. Explanation of above picture. Permanent live wires connect to the loop terminal and all earth wires connect to the earth terminal. Video explains the connection required within the ceiling rose one way switch and. This is a loop in method which can be useful where the light fitting only has three terminals or when using downlighters. Loop at the switch.
1a this is the most common loop in wiring arrangement you are likely to see. Some installations may have additional out cables. Student training aid for the connections required to wire a lighting circuit using the 3 plate loop in method. The power from the mains consumer unit runs into each ceiling rose and out again then on to the next ceiling rose. Lighting circuits loop in loop out. Loop in as the red wire from the feed cable the black wire coming back from the switch is connected.
It shows three cables. One way lighting circuit using loop in ceiling roses. The ceiling rose should be wired as shown below. For example in our loop drawing below pdt pressure differential transmitter 42 has an input. These are all connected in the same way to neutral earth and loop.
