Looked at a job today and found something which I believe to be odd.
TNCS system with tails out of the new smart meter into a small henley block. Then 1 set of tails only from the henley block into an old square d cu. The thing I found odd is that the henley block has what I assume is a DNO lead seal.
The customer has asked for a new circuit, so my plan would be to split the tails and install a new CU with RCD etc.... Where would I stand with cutting this seal to gain access to the henley block as it is after the meter.
My understanding has always been anything after the meter (or DNO isolator) is customer owned and thus fair game.
