I have just fitted a Dual RCD split board consumer unit to an existing installation. I wired the upstairs lights to one side and the downstairs lights to the other but when the landing light was switched on the RCD tripped so I looked inside the switches and the feed to the downstairs switch was shared with a hall light.I suspected an imbalance triggering the RCD. I then connected both upstairs and downstairs to the same RCD but had the same problem ,also with the other RCD. Does anyone have any suggestions please?
