Hi I'm in need of some help i had a fuseboard changed to a dual split rcd protected board as our old one was way out date, the cables were extended using juction boxes and the correct cables have been used the terminations themselves have been terminated like for like too! When the electrician made it live the lighting circuits tripped the rcd, I've had a look on other websites about lighting circuits and faults it may possibly be and noticed most lighting circuits have 1 1/1.5mm twin and earth at the mcb yet mine has two? Could this be causing the problem ? Would like to know a little if I can as to why it would even have 2 in the first place it all looked origanal when he took the thing apart any help would be appriciated gcs
