I'd be interested to see how connections like this would actually carry the high fault current that they are supposed to. What sort of filler is that, in that piece of NM cable?. It looks like it would burn pretty readily.
Wasn't the cold water allowed to be used as a GEC/EGC up until prior to '93 NEC? When did the 5' rule come up for point of connection to water? It was the way it was done for a while, not sure when that 'while' was though. It seems 40's- 60's.
Trumpy, that filler is craft paper, still used in romex, and other cables.

I remember dad using that cast-iron pipe. To seal it they rammed tow (oakum) and boss-white, (a mix of powdered chalk and linseed oil), in the annulus, followed by lead-wool hammered in with a wooden spoke. Another American pipe used in the UK at that time (late forties) was made of paper-pulp and molten tar,(made in a vacuum), with the ends taper machined. It was brilliant- light, strong & supple with foolproof joints- just hammered together with a dolly. Then upvc arrived. Alan
