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.

    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 ?

    Well Mike, if you did need a C.P.C. (or earth wire) the company can supply A Wiring System With Bonding Wire. Catalogue Section BJ. It is called The Henley Wiring System With Bonding Wire. The wires "Carry their own protection" in the form of a separate earth conductor integral to the cable. Class EZ is for single cables with bonding wire.

    Twin cables with bonding wire is Z2EF . And a triple cable with bonding wire is Class Z3MF.


    The wires are tinned copper. Insulation is vulcanised India rubber. 


    The test pressure was 1,000 Volts for 15 Minutes after 24 hours immersion in water at 60 degree F. (15.6 degrees C).


    Available on 50 or 100  yard drums.
