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

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.

The junction box effectively replaces the ceiling rose with the ceiling rose, the IN cable supplies power from the consumer unit or previous junction box, and the OUT cable connects to the next junction box. These cables have permanent live, neutral and earth wires switch connects between the permanent live and the sw..See more on flameport

Switch loop through (the circuit connects to each switch in turn, and a separate cable goes from the switch to each lamp) Junction box loop in, where the termination and feed connection are done at junction boxes, and cables run to switches and lamps from there. The diagram is shown with 6A lighting fuse and 32A ring circuit MCB.
Surewire - Pre-wired Maintenance Free Lighting Junction Boxes
Surewire are pre-wired maintenance free lighting electrical junction boxes that have been designed and developed to be a replacement for single junction boxes, the loop-in ceiling rose system and downlighter junction boxes. They aim to be the new standard for wiring a lighting circuit.

Type one lighting circuit. The second system in popular use is the junction box circuit or system. Power is taken from the consumer unit to the first junction box. The live is interrupted by the switch wiring and the circuit is carried on to the next junction box. A cable is run from the junction box to the light, usually via a ceiling rose.
