Lighting Circuits using junction boxes - John Ward . Junction box sizes. Although a 5A junction box is suitable for a lighting circuit (even if on a 6A circuit breaker), it is generally much easier to use 20A types. These are larger and have more space for the wires. There is very little difference in price between the 5A and 20A types, so there is no point in using the 5A ones, unless the
Wiring Diagrams For Lighting Circuits - Junction Box Method . Wiring diagram of a one way lighting circuit using junction boxes (fig 1). fig 1 The junction box should be wired as shown below. fig 2 Explanation of above picture.

Junction Box Wiring ! diagram - Connecting cables using a junction box Creating a Spur using a Junction Box If you want to spur off from a current circuit to provide power to a new socket of light, again, make sure the power is off and the circuit is isolated and wire your junction box using the method below. One Way Lighting Junction Box - Diy How To . One way lighting circuit using junction boxes . Line diagram of a one way lighting circuit using junction boxes (fig 1). fig 1 . The junction box should be wired as shown below. fig 2 . Explanation of above picture.

This would be cable A in the diagram below (Fig 2) which shows how the junction box is terminated. This live feed now loops back out of the junction box (cable B, Fig 2) and feeds power to! the next ceiling light in the radial circuit (junction box B,! Fig 1). This repeats for each light in the circuit until we reach the last light.
