outdoor light

[bigQ]

Hi
can anyone help me please.
I have put up a outdoor light. (Not pir, just normal on/off).
I fed a cable from an existing rose.
Live to the centre connectors.
neutral to the neutral connector( not the sleeved live).
earth to earth..
this is fed into the outdoor light, which has a block connector in it.
this has a line, neutral and earth , retrospectively wired into each block.
I have wired the cable from the rose, into the light, with each wire connected (Line-Line, Neutral - Neutral and Earth to Earth).
I have then fed a cable from the light connectors, wired as above.
This then leads to a switch, line to Com, neutral, sleeved live wire. To L2. Earth to the pattress.
when I turned the power back on, the light worked, (switch was in the on position).
when I flicked the switch, it tripped the mcb.
Does it matter which connection the live switch, sleeved wire goes into, L1 orL2.?
Have I connected it up wrong somewhere?.
Thanks in advance

Yes you have wired it incorrectly. Look in the Wiki and you will find a circuit


You will need a 4 way terminal block at the new lamp.

Neutral from rose to neutral in new lamp ( TB 1 )

Live from rose to brown wire to switch ( TB 2 known as loop ) Does NOT connect to new lamp.

Blue wire from switch ( switched Live ) to live on new lamp ( TB 3 ) This should have a brown sleeve on it as it is switched live and NOT a neutral

Earths all joined in TB 4

What you did was connect the switch across the live and neutral which put a dead short across the supply hence the MCB tripped.

So just make sure I've got this right.
1.my wiring at the rose is correct.
2. I need a 4th block in the light, it only has the three.
in this 4th block, I connect the line from the feed cable from the rose, to the com connector in the switch. ( would it be ok to connect the switch wire and feed cable in a block at the lamp for this?)
3. The neutral from the feed cable, to the neutral in the lamp.
4. The blue (switched live) to the live wire in the lamp.
5. Connect the cables earths, to the earth in the lamp.
