Tripping next doors RCD

[bgec]

Hi to all The other day I found the fault on a ring main this was repaired and when I was testing the circuit (RCD Test) the neighbour came over and said that his RCD kept tripping I was confused When I tripped the RCD in the house with the test it tripped next door at the same time to me that is wrong
I will be honest I have not much experience with TT systems and this is a new one on me too

Thanks Guys

The only way I can think of is that they somehow share or have a cross-connection on a L or N?

Hey.

This sounds really quite serious, I would get on to looking at this ASAP perhaps a call to youe DNO may be in order too. From what your saying any fault current that originated in one property could transfer to the other one and if bonding isn't up to scratch the someone may get hurt!!

Cheers.
