Reviving an old thread to get advice from sifus.......
I jut bought bout 3 dozen lights for new house, mostly ceiling mounted led panels.
The shop's installer say standard rate is RM15 to install one light.
I reckon each job will require : 2 screws to fit light to ceiling, connect 2 wires, pop the cover back.
Most of the ceiling is plaster ceiling board. Drilling not a problem.
So I am thinking to DIY myself.
Before I fried myself or burn a row of houses, can sifus check if I got the theory part right :
Most of my lighting points like this :
[attachmentid=4125683] [attachmentid=4125699] [attachmentid=4125701]
Q1
The middle wire can be red, yellow or blue. I think this is the wireman's way to identify each 'loop'
Correct?
Q2
So the Black = Neutral; Red/Yellow/Blue = Live; Green is Earth.
Correct?
[attachmentid=4125688]
Q3
The LED lights has 2 tiny blue wires. These are to be connected to the Neutral (Black) and Live (R/Y/B)
Which way also OK. Correct?
Q4
No need to use Earth (Green) wire.
Correct ah?
Q5
There are two black and green wires each because of looping. Just leave them alone. Don't pull out.
Correct?
Q1 = that is live wire. Not loop. And probably a 3phase wire. Which each color represent R, S, T. I jut bought bout 3 dozen lights for new house, mostly ceiling mounted led panels.

Q2 = correct.
Q3 = if the wire have same color, that mean no polarity. Which way also can.
Q4 = if your downlight casing is metal, you need to ground it. In case the light short and somebody touch it.
Q5 = correct. If you pull out, others light will not light.
