New Extension Lighting Problems


Postby francomac » Fri Dec 30, 2011 10:33 pm

Hi guys looking for abit of help here. Im currently building a side extension onto my house. Just got to the stage of wiring up the lighting circuit. Im using a wylex 6a type B breaker with 2 core 1.5mm cabling.

Ive wired up the lights to a 4 terminal 20A junction box.Which I'm sending down to switch back up and into light. The lighting circuit itself is around 15-20 metres long. Heres the problem i have when connect into the board the 6a breaker keeps tripping. So i started fault finding and the wife was getting kinda pissed with the power on power off scenario so i connected the lights to some cabling and a plug and plugged the lights in temporary. When i did this the lights worked perfectly. circuit was complete and fine. So i went back to the board took my tails out of the 6a breaker and inserted into the spare 32a breaker i have in my board and again the lights worked perfectly.

To test if it was the new 6a breaker that was faulty i disconnected an existing light circuit that i know the breaker is working fine and still the breaker tripped.

In my circuit is only four lights and four switches so i can't see why the 6a breaker should be tripping.

Any advice would be greatly appreciated as I'm totally bamboozled.

Cheers

Frank

francomac,
If the mcb is tripping without the lights on then there is wiring fault. If all your cable runs are unbroken between the junction box, switches and lights then have a check on the wiring in the junction box. Also check you haven't put a nail or screw through the cables.

all the cable runs were complete no nails etc..
i moved the 6a breaker to the other side of the board and it all works well for now.
