Any professional sparks about, question, just working on my mates house & switched his old fuse based consumer unit to a split load box, all connected up fine & working, except the rccb, its crabtree split load rccb on of course split load busbar, has top/bottom neutral & I am assuming its an in/out neutral that seperates the neutral circuits from the standard unprotected circuits, so I then stuck mcb on the protected side & wired in a circuit, but as soon as I turn mcb on the rccb trips every time, tried different circuits, lights, ring etc, no matter what it has connected the rccb trips, I got another one but havnt tested yet but they're fairly reliable so thinking maybe its a wiring issue
Any ideas?
Could it be a bad earth, as the main earth comes of the gas pipe from the ground & cable isnt that thick of diameter, do you think it needs an earth stake & larger cable for decent earth or reckon its a fecked rccb cause I can of course turn it on but whenever current passed through it trips.
Any help would be much appreciated.
Thanks.
