Hi, would like to seek for opinion from any electrician with experience here.

I am in the midst of arranging to renovate my house (three phase wiring terrace if it matters)

living room has 4 lighting points total, one switch = two points. total 2 light switches.

I engaged with a general contractor, I wanted to make total 8 lighting points for 8 surface lights instead of the original 4. Means 1 switch = 4 points. He said cannot for this type of LED light because will cause tripping, but the lighting shop people tell me it doesn't matter how many lights I put since they're all LEDs they don't draw much power anyway. He said must create new lighting switch from the distribution box.

1 LED surface light = 36W

Can anyone please advice me if contractor is right or lighting shop ah? icon_question.gif thanks!

On the box:

So you mean total 2 switches, when you switch on 1 switch then 4 lights will on ?

HI, checked the db, it says 10A, wires look thick too. In your opinion do you think this is fine? Thank you so much for your input

You want single 10A MCB to connect 8 units LED light each unit 35w?

And apparently 2 fans also. Overload?

If 6 lights + 2 fans?

Shop people are right.

LEDs, fans all low wattage, would not cause trip.

Something like this contractor also don't know, better change contractor.

10A x 240V = 2400W

80% 2400W = 1920W

36 x 8 = 288W + 2 fans still below the 1920W.

Should not be a problem.

Thank you very much for your feedback! I appreciate it very much. Is there a certain type of wire thickness that I need to insist for the contractor to use?

I see, going by this chart I guess I don't need to insist any type of wiring thickness then, thank you!
