I'm abit confused...

Can someone guide me, I need to DIY my ceiling light replacement....?

Please do not DIY if you even not know how to differentiate green, blue and black in the first place.

Hire electrician to do the job, electricity can be dangerous, if not know to handle it.

Standard
Black - live
Blue - neutral
Green - earth.

green = ground
blue = neutral
black/red = life

most importantly the main switchbox is off n use test pen to detect any power leak...

there is no fix standard on wiring color code, different country different std

for single phase,
normal 3 core wire:
Brown=L
Blue=N
Green=E

wire pull by electrician/ provided by developer:

red/yellow/blue=L
Black=N
Green=E

That's the confusing part...


red/yellow/blue=L
Black=N

or

Blue=N
Black=L

1) Write down the colour code on existing connector
2) Check whether any indication there.
3) Normally Earth should be Green
4) Use Test Pen to check, if LIGHT UP meant is LIVE
5) The list one should then (without light up when use Test Pen) should be neutral

* Please correct if wrong statement

most important is have a, working test pen...

and also some basic common sense... and ur all good to go

for malaysian wiring colour code

Red/Yellow/Blue - Live

Black - Neutral

Green - Ground/earth.

but for electrical appliances (plug/fluorescent fitting) it's depend on the country of origin.. it's a little bit different like.

Brown/red - Live
Blue/black - Neutral
green - ground.

u better hire a electrician, pay then settle

what i do is use a test pen to find the live wire

The problem is electrician not even bother to pick such small job...



Gonna 'force' my contractor to settle for me...

easy rules:

Earth= always green
Neutral= No colour, ie black or white
Live= Coloured except green!

the different colour of live wire used by the electrician is to differentiate type, zone etc...

Thanks all for the help. I "survived" and successfully installed my ceiling light via DIY.

Very helpful information, indeed!

Good thread indeed. Last time, I tried to install my own lamp, just 1 lamp (the wiring is there already, hanging on the ceiling), i googled around and it's very confusing but i managed to do it ..

for lamp fittings, Neutral and Live is not important. Both connected to the terminals anyway. Just make sure the earth wire is not connected to one of the terminals or the Live not connected to the metal body...

who suggest replace a light need to hire a electrical man?? so malaysian... lols..

replace the light is js a piece of cake la, even ah poh can do that. most important is don't forget to switch off the power first.

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 :



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?




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.

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.

how you guys connect the wires together?
using those terminal blocks

or these electrical caps?
