    Lead sheathed 2 core lighting circuits /EIC

    Evening All, I'm changing a CU from rewirable to 6 x RCBO in a Victorian flat.

Thanks for any pointers, Pete

    Hi, I have wired a 2 core inline lamp switch that has no markings for the terminals but not sure it's correct. There are 2 raised terminals in the centre but each has only one inlet/screw, so I used the terminals at the side but it isn't working. Thanks in advance.
