Hi, I've just started an apprentice course so very green but I've been faced with this issue and can't work it out.
Two way light circuit in a garage each controlling 8 x 70w fluorescents. I've never seen a two way wired this way and need help understanding it. Each switch is identically wired and has a 3core + earth and a 2 core + earth inside the back box.
In each switch earth from 4 core and 3 core are connected together.
Re 4 Core, brown is connected to L2, black has brown sleeve and connected to L1, Grey has blue sleeve and connected to neutral from 3 core. Brown from 3 core is connected to common on switch.
I can't work out how this is functioning as a two way as there seems to be two 3 cores for load in? Also I need to remove one of the switches and put an occupancy sensor in which just has a live, neutral and switch live so unsure how to wire it.
Can anyone help me?
Thank you.
