Hey there everyone, I have a question hopefully you can help with. A job where ive fitted a new circuit on to the fuse board is having problems with the RCDs. Its a split load board so has the Line and Neutral supply into the 100amp main fuse from there Neutal up to the neutral bar and Line over to a 80amp RCD, from there is a Neutral feed from the same bar as the 100amp neutral and a Neutral to a seperate neutral bar for that RCD and another Neutral and Line that goes onto a 63amp RCD which then has a Neutral going to another bar for that RCD.
When the 80amp RCD trips the 63amp RCD stays up which it should, but when the 63 amp RCD trips it takes out the 80amp 1 to. I dont understand why. Any help would be much appreciated
