Thank you

And i have a bigger problem involving possibly a fuse box and a leaky roof.

quick question... why does the neutral and earth has many joint wire together?. is it shared neutral?

Yes

Hi, anyone can identify which L and N wires goes to Load? because there is no Load marking on the switch itself. I only see only L1, L2 and L3.
The white colour wire is incoming Live from the DB and I need to find out which is the incoming N and out going L and N that goes to the Load.

PDL 20A switch


View from the bottom


View from the top

If you switch ON and the red light is ON, than the wire from DB is bottom. (2nd pic)

Cause the red light lamp attach to the TOP.

Like this ?


Yes, the red light is lighted. So the small led wire should be connecting L (load) to N (load) right?

yup. correct.

When switch ON, the load side have electric flow. Than will light up the light.

Thank you sifu,

Successfully replace the switch as per your guidance.

Hi all,

I have a noob questions to ask for help. I'm trying to figure out whether I can loop a power point for use like laptop or charge phone from existing light switch.

Is that possible to add that? Or still need wiring like neutral and earth.
Is a bit hard for me to get the neutral and earth wiring as it's all sealed inside a partition wall.

Thanks in advance.

Duplicated.

Not possible, you only have live wire.

What you want to do (for all intents and purposes) is not possible

Without N and E, not possible.

And the switch wiring also wrong connection. The COM should be L (yellow) and loop to another COM.

Red and blue should be at L1 each.

Not possible. This L circuit at the switch doesn't provide return neutral and earth required for 13A socket there.
The lights' N is connected only up to/at the light point.

Thanks all for the advise.
The connection are done by contractor 🤭
I'll correct it back then, really appreciate for the comments!
Thanks 🙏

Hi, how to connect this two core copper wire to the plug? i assume just connect either one of the copper wire to Live and Neutral, correct?

Depends on what is on the other end if its a lamp (based on the thin wiring) then either one will work.

Hi, I am facing an issue of identifying which wire color label. I am attempting to upgrade my Storage Water Heater switch to to Sonoff tx wifi smart wall switch. There are three colors Red, Blue & Black.

Can anyone help me match the wiring to the diagram please.

you cant use that switch.

max rated output only 2 amp.

water heater takes much more than that.

Is it?
What should be the power rating I need? Any suggestion of which Smart switch I would need for a storage water heater please?

Thank you
