Very interesting. Sounds as if much of the wiring is done in 'capping and casing', so likely to be old vir cable. Little chance of earthing involved with lighting circuits, at least.

Yes I've found capping and casing run in notches in the joists. Sometimes a red and a black wire, sometimes just black wires. No earth and insulation looks a bit like the braided cloth type seen on some steam irons and the like.

Soundslike the old cotton insulated wiring. We have lots of it still in my area, the general rule of thumb here is if it passes an IR test leave it but as soon as you need to disturb it or work on a circuit then it's a rewire job.

Do you think it's possible that the supply was originally DC ? The last time I saw supply like that was on a private estate in Scotland which had its own generator for the lighting which was installed in the early 1920s.

Every chance it was DC. The few I've seen like these were on DC up until the end of the war.

Bloody hell, .... by the look of that fuse wire your up in the 100's of Amps!! lol!! Your fuse and tails look as if they could supply the street!! lol!!

there's still a lot of these in old tenemant buildings in Glasgow, very few in use but they got left there inside the front passage doors on the wall above head height just cut off and no longer in use....
