Lighting Wiring Consideration.

Zoomup
I am going to use some Henley Paper Insulated House Wiring cable for a lighting circuit. The manufacturer is W.T. Henley's Telegraph Works Company Ltd., Holborn Viaduct, London E.C.1.I am using their Section CA catalogue.

The cable is called YT type. It is paper insulated house wire.


I am thinking of using 3.029 inch twin cable. It is rated at 7.8 Amps. I will use a 5 Amp fuse in the fuse box.


Q1. What is the cable outer covering made of?


Q.2. What is the weight of the cable per 1,000 yards in cwt?


Q.3. What is the price per 1,000 yards.


The year is 1927, the month June.


Z.


Edit. Some minor typos corrected.

    informed guesses, based on old cables seen in the past, and the historical price of other things plus a bit.

    I assume you mean 3/ .029"  so three strands, each strand is 29 thou in diameter. closest modern would be 1.5mm2, but it is stranded as 3 strands of 0.5mm2

    So

    Silk or cotton braid.

    about 1CWT.   (8 stones 112 pounds, lets call it 50 kilos for 1km length.) I'm assuming the copper is most of the weight, and perhaps 20-30% more for the paper and silk.


    between and £10-£15 ?


    Coal Fire heated soldering iron iron tinned and ready to sweat the joints, with a roll of empire cloth tape at your side to make good eh Z ?

    Still, no lighting CPC to worry about for another 40 years... How much cable design changed in those decades, and how little in the 50 years since ?
