110v temporary lighting questions

[dave19]

Hi Guys,

Not long in the game and even newer to temporary lighting.
Normal and emergency lights are up. The emergencies have a 4 core (black core for battery). However some of the normals also have 4 cores (not sure why).
Anyway we are using a 4 core cable to feed these lights as they are being switched. How to I connect these in the junction box at each fitting ?

what junction boxes are they? are they gregs/klik roses?

Spider boxes

Just to add they are being switched via a sensor

What's a spider box?

JB feeding 7 lights. 8 cables into it, hence arachnid.
