Garage consumer unit rcd trips out

[Mr Karl E Taylor]

Yes

The two of the six are they wired so they both switch together on two way from each door have I interpreted this correctly? And is it a correct statement that it is only when you switch this bank of 2
lights it trips the RCD

 

[Toneyz]

Yes

Do these two lights that are 2 way switched together trip out the RCD with the other lights off?

Yes one of them did .so i swapped it over from one at the front of the garage and the other one to the one at the back of the garage taking them both off this 2 way circuit.
Made no difference it still trips the rcd with the light swapped over.
So my hunch is now they all have live supply going to them regardless of the switch and its the discharge going back to earth from one of them causing the rcd to trip out
