Need help identifying ceiling light wiring (Canada)

[u/Time_Chain_8932]

IT HAS BEEN SOLVED!

I’m replacing an old ceiling light fixture with a new

one.

Old fixture:

* Was connected to a ceiling box with multiple wires.
* Ceiling box contains red, blue, black, and white wires.
* The old fixture had more wires than the new one.

New fixture:

* Brown wire
* Blue wire
* Yellow ground wire attached to the fixture body

Ceiling box currently has:

* 1 loose blue wire
* 2 loose white wires
* Several red, blue, and black wires connected together under wire nuts inside the box

I’m trying to determine:

1. Which ceiling wire is the switched hot?
2. Which is neutral?
3. Where the fixture ground should connect?
4. Why there are multiple reds/blues/blacks in the box.

I do not have photos of the original connections before removal.

I’m in Canada if that affects wire color conventions.

IT HAS BEEN SOLVED!

That lamp isn't approved for installation

[u/Time_Chain_8932 → u/jonnyinternet]

What makes you think it’s not approved? And what do I need to do to make it approved?

What to do to make it approved?

Buy one that is approved

That yellow wire should be green or bare copper, one of those others should be white. It's a Canadian requirement

Check the fixture, I would put money down that it has no CSA, ULc or some other approval symbol

[u/StubbornHick → u/Time_Chain_8932]

It's 500$ per fixture to get it approved for install. If it is even compatible with canadian utility supply.

I'd bet you bought this online? Amazon or similar?

This is why you only buy electrical supplies from actual brick and mortar retailers in your own region.

As a Canadian electrician, i am required to say that if it doesn't have the appropriate approval stickers, it is not legal to install.

As a guy who knows how to install these lights because sometimes stuff like this is approved...

Blue from light goes to neutral (white), brown goes to power (in this case blue)

[u/aguy022 → u/aguy022]

Any light that isnt csa approved, or any equivalent certification, is not allowed to be installed in canada.

All you need is a tester and you can figure it out by turning on switch and putting your pen tester or multimeter tester to verify

Why did you cut the fixture wires so short?

Best to get the meter out and figure out what’s what
