I was called to an office in a field today (tt system)
The led lights and sockets (separate circuits ) still have power when switched off at the switches ( lights on dim and socket neon half bright)
I did a ze test at the board and had to replace the earth rod.
The reading at the board is now okay but when i plug in my kewtech meter to do the zs the RCD trips
It also tripped on x1 trip test but failed to give a reading (it said NIL)
They have had loads of different unqualified electricians working in there and its a busy office where do I start?
