Hi All,
Hoping someone can give me some idea of where to investigate:-
I'm getting occasional (ie about once per fortnight) RCD trips, which happen at events on non-RCD circuits. I'll explain....
I have a split load CU, on a TNS system. Main and supplementary bonding is to 16th edition. Non RCD side of CU has cooker, immersion heater (turned off), smoke alarms, garage, central heating, two lighting circuits.
RCD side has upstairs ring, downstairs ring, kitchen ring, utility room radial on it.
The last 2 RCD trips have happened on the following circumstances:-
- Turning the oven off
- Turning off a light upstairs, bulb blew, RCD tripped.
Both of the circuits are on the non-rcd side. And i'm 100% certain the RCD tripped at the exact moment the two events happened.
Any pointers for investigation much appreciated.

I'm certain there is no crossed neutral, all circuits have IR > 200Mohm. I'm at a loss. Any ideas?
