Trying to understand this, as it really baffles me. In short, what does the RCD do? Background to question:
The other night our power went off momentarily and tripped the RCD. I could not put the RCD back up - something was forcing it to stay off. So I turned off all sockets and the RCD then worked again. But, have since turned all back on again, and no problem. All the while, the lights all stayed on - so lights not on same circuit as RCD? That I get. This is where it gets weird.
A neighbour sent an SMS after the power cut with the same problem (she lives alone and was worried I think). Power cut, then sockets not working, but lights OK.
Now, I assumed that the power cut / surge (whatever it was) upset one of my appliances, but after turning everything off and on again (OK, not everything, I didnt turn off the central heating controls, but everything else in all rooms was turned off) it was OK.
But, if a neighbour had exactly the same problem, this suggests that not an appliance (unless a coincidence?). Houses were built at the same time, so have same fuse box / consumer unit.
I am just trying to understand what might have happened. Does the consumer unit have some sort of time delay in it? Or does turning sockets off lead to a reset? #confused
