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.
