Anything weird id usually neutral fault 😀

OK so found the issue. Tested circuits all fine in regards of ir tests. Rcbo ramp test 24ma so that was fine. Issue only happens when...

Yes it was tucked behind the din rail, CEF Leyland stock them. Better price than Fusebox just no 25a option yet.

Was the N fly lead tucked behind the Din rail by any remote chance? Where do you get Niglon RCBOs from in Preston?

It would be worth trying to identify a new RCBOs from a different batch date in case it's manufacturing fault.

Will let you know. It's a new board so all same manufacturer. Picking up new rcbo this morning and heading back there.

Have you ramp tested the 6A RCBO to see how sensitive it is? i.e. to give you some idea of what sort of "apparent leakage" current you...

But no current flow. Dp isolator is off as no immersion connected yet.

higher load, higher neutral voltage with reference to earth. more current flows N-E and trips the RCD/RCBO. see it more with higher...

I thought induction, but there is no load on the immersion yet. It goes from board to time clock then down to 20a dp isolator all new...

Check you haven't a neutral earth short in the immersion isolator switch. Is the immersion feed clipped immediately against a lighting...
