Hi my brother in law has a crabtree split load board, the installation is fairly good, all bonded correctly and the cabling is tidy. Everything in the right place and tight.
The lights are on the non protected side and the sockets are on the protected side as they should be....
However, when the lights are turned on (this can happen on 2 separate light circuits) the rccb trips, and the protected sockets lose power. The lighting circuits however stay energised.
They have lived in the house for 2 years and have had builders in the whole time the board was installed just after they moved in by a sparks - family friend who is no longer a family friend (for other reasons...).
Having had a good look at the installation, the only 2 things I can see as causing this are a shared neutral or earth between the lighting circuits and a socket ring, or a faulty RCCB.
Anyone got any other possibilities? I'm going to pop round with some test equipment over the weekend to have a better look, but I'm having a hard time trying to work out what the poss causes are.
Thanks,
Kev
