Light with 3 Power cables problem


Postby xian » Tue Aug 07, 2007 4:11 pm

Hi All,

Today I bought a bog standard light fitting from Homebase with 3 wires and a terminal block with 3 opposites.

I got home, cut the power and took off the existing ceiling fan / light that was there. Now I am stumped as there are 3 power cables, each with three wires, and one of the black wires has a red band on it (indicating the switch i assume). I have tried all three cables in the jacks seperately and in most combinations I can think of but they either result in the circuit tripping or nothing happens.

If you could possibly offer any advice I would be very grateful.

Many thanks in advance

YOUR 3 CABLES I PRESUME ALL TWIN CABLES, RED , BLACK, + EARTHS. ( AS U SAY 3 POWER CABLES 3 WIRES )
EARTHS GO TOGETHER IN A TERMINAL BLOCK, AND SHOULD BE
SLEEVED WITH GREEN AND YELLOW SLEEVING.
REDS ARE CONNECTED TOGETHER PUT IN A TERMINAL BLOCK AND TAPED UP ( THESE R PERMANENT LIVES ).
THE BLACK WITH RED TAG IS YOUR LIVE SWITCH WIRE.
THE TWO REMAINING BLACKS ARE NEUTRALS.
OK NOW THEN , AT YOUR FITTING TERMINAL BLOCK YOUR BLACK WITH RED TAG ( SWITCHWIRE LIVE ) GOES TO BROWN OF TERMINAL BLOCK,
YOUR BLACKS ( NEUTRALS) GOES TO BLUE OF TERMINAL BLOCK, AND
YOUR EARTH ( GREEN AND YELLOW) GOES TO GREEN AND YELLOW OF FITTING. VERY VERY IMPORTANT THIS CONNECTION IF FITTING IS CLASS 1 METAL. MUST B EARTHED !
