Hi guys, looking for abit of help.
Carried out a consumer unit change today, carried out all dead testing etc, all came back ok.
New board is a twin 63a RCD.
With the following configuration both RCDS tripped straight back out.
RCD 1 *upstairs lights
*Downstairs sockets
*Boiler
*Bathroom Low voltage
RCD 2 *Downstairs lights
*Upstairs sockets
*Cooker
If I swapped the upstairs lights over to RCD 2 however + then swap the downstairs lights to RCD 1 there were no problems.
I did find some kind of neutral interconnection via insulation resistance testing between upstairs and downstairs light circuits. which came back as 0.03 ohms.
Any ideas as to whether this would cause the RCDS to trip as described above and if so what the best possible way of tracking the fault would be?
Any help would be much appreciated.
Regards. Rich
