Just been doing a contract job for a contractor that is working on an NHS site, senario: two story block student flats, two D.B's one on each floor, fed in pyro some 50 m run no bigger than 6mm, only earth was of inadequate size off the conduit box terminal, so this contractor has put in two 16mm earths but taken them to two earth spikes therefore mixing earthing arrangements ie its now earthed as a tt would be but mis supply at source is tnc-s.
And one other thing a new water heater has been fitted and it required 3 x 3.3 immersions wiring to it, in the haste of the job their gaffer forgot and when we told him it required this he told us to wire these off the ring main...which we did not, that aint right in my eyes is it ?
