I want to install a light fixture on a box that's in the ceiling. I opened it up and I saw WAY MORE wires than I expected. I expected just a green, black and yellow wire.
Here are two photos of the wires.
Here's a close up.
Can someone explain what each of these wires do? I see a single green wire, a single blue, 4 green wires twisted together, 4 white wires twisted together, 4 yellow wires twisted together, and a single red wire that I can't pull out of the box. Which one do i use as my ground, live and neutral wire?
Just to give some context, I live in a condo in Toronto, Canada. The condo was completed in 2014. Thanks.

Some condos are multi-use, i.e., both residential/commercial mix, so maybe it's possible the yellow is a high leg, 277V for the common area lighting that is just there for "future development". Ask the building superintendents. They are usually filled with many great stories of advice.
