That would be wrong as the 30mA is at the socket and not for the circuit. -

I very much doubt it’s faulty but it did look 2nd hand Your mothers house has existing faults

Tim Howard reacted to mainline's post in the thread Single or DP RCBO (Debate continued, split from "old fuseboard" thread) with Like.
DP rcbo is most beneficial in a TT earthing system where an upstream rcd is being used.

Tim Howard replied to the thread Completing test sheets on circuits. With rcd protection and and rcd socket outlet.Sure I meant his colleagues were suggesting listing 30ma as the RCD for the circuit, creating the wrong impression.

Tim Howard replied to the thread Completing test sheets on circuits. With rcd protection and and rcd socket outlet.I agree with you, you should record the protective device and additional protection provided for the entire final circuit. Otherwise...

Tim Howard replied to the thread Single or DP RCBO (Debate continued, split from "old fuseboard" thread).I used to think that DP RCBOs were more essential than they in fact are. Detection is the same. A L-E fault is isolated. An N-E fault...

Can but more often than not the tripped RCBO is the circuit with the fault

That’s true but a DP rcbo will isolate the circuit that causing the trip where as an SP one won’t.

Tim Howard replied to the thread Single or DP RCBO (Debate continued, split from "old fuseboard" thread).It's quite easy to talk at cross purposes here. The point about RCBO boards is the N's are joined upstream of the RCBO test coils that...

most likely you've got a fault that was always there before the board was changed, however the old one couldn't detect that fault so was...
