Need electrical wiring help

[Joemit7850]

Hi

 

I replacing my existing T5 batten on my cove ceiling to LED strip light.

 

I notice the previous electrician had this wiring connection

 

2 black wire (N) - 1 connector

1 red wire (L) - 1 connector

2 earth wire (E) - 1 connector

 

instead of 1no of each N,L,E from my LED.

 

How do i connect?

you cannot connect the led to ac directly, it will go kaput. Unless you bought ac led strips. Else you will need a transformer to step down 230v ac to 12 v dc. Power rating of 12v power supplies depends on length of led strips. Hope that helps. :)

sorry, forget to add, i had led driver as well 24V

however, is the AC to the led driver parts which i am confuse as normally only 3 core.

Does your LED driver comes together with the LED strip/blubs?

If not do check the voltage requirements for the LED blub/strip first as connecting 24v to a 12v device will kill it.

 

Normally LED driver will have 1 input (which is for the AC source) and 1 output (which is stepped down to DC 12v or 24v for your case).

Just connect your wires accordingly and it'll work. Some LED drivers have only L and N input, so you can actually ignore the E cable, thought it is good to have the E connection as well.

The output will be + or -, so just reverse the cables if it does not light up.

Just connect the N,L,E of the Led driver accordingly, dont have to worry about the 2E and 2N wires, leave them as it is, its either looped to the next circuit in the house or a return circuit to the distribution box. Do not disconnect any of them.

i had tried to connect them normally but keep on trip when switch on

but when i connect them directly to 3 pin plug, it works...

so i quite sure the wiring is correct

no...the led is separ from the led...

If the current connection of works with your T5 tubes, i really don't see why it can't work if you'd connected it correctly to the LED driver... beats me..

I can only think of some wires bring shorted to E that causes the trip.

But interchanging between L and N does not matter.

 

Another cause of tripping could be overloading (slim chance). Since there are 2 pairs of L cables, need to trace where the other cable is connected to and see the load there.

 

Was there any dimmer at the light switch?

no dimmer for this switch, but this use to come with IC controller which to control different light on pressing the switches

however, i had taken out the IC controller..

ya..is quite straight forward but just couldn't work...think i have to ask my technicial tomorrow.

Trip means shorted or wrong connection.

 

Try to take upload some pictures of current and LED lights.

 

Maybe that will will be better.

 

The older CFL tubes, with ballast and starter type to convert to LED drop in tube, will have a few more steps to complete the circuit.

 

For one to one T5 to LED should be quite straight forward.

 

 

Dont give up yet.
