  • What code is it? 

    Code? is that something that should concern the DNO? The service looks perfectly ok, as the "tester" comments, a low impedance. Although obscured, the method of bonding the two lead sheaths together is likely to be as was done in those days, a 7.029 plumbed between the cables, and "improved" with a 951. 


    Have I missed anything? Oh yes, the ISCO cut-out, the fusing as far as the curious are concerned, N/V, (not verified) Out of scope of the BS7671.
