I had a new CU installed in 2021 - dual RCD. This morning I was using the toaster and the RCD tripped, taking out several circuits including the downstairs ring. I have two questions as this is all new to me.
How easy would it be to split the downstairs ring so that the kitchen and living areas downstairs were on separate sides of the CU? Would a new ring need to be installed? Things like the alarm box, router, digital phone etc. went off and took some time to reactivate.
I don't quite understand the physics behind why the toaster tripped the RCD. I have read several old posts on the forum saying that burnt bits and other debris in the toaster can cause this, but why? No fault in the toaster or wiring, so what exactly caused it? I did shake out quite a bit of stuff, plugged it back in and now it's fine.
Yes, I am sure that it was the RCD that tripped (not the breaker) and yes, I did have an EICR before the CU was installed.
