7/.029 Twin & Earth Cable.

Zoomup
I have a job to update an old installation. It was probably installed initially in the 1960s. There are many radial circuits that would have run to just one socket outlet, probably a 15 Amp type with round pins. The cable is in excellent condition and I will retain the radial circuits and use 16 Amp R.C.B.O.s for each radial circuit.


The wonderful thing about the cable is that it is so flexible. Also the live conductors have seven strands and the earth has three stands of wires.


Wonderful British made cable, unlike the tough 2.5mm2 metric stuff.

    Obviously when copper was insulated with P.V.C. the tinning process was then unnecessary.

    But standards probably took a while to catch up - as far as I recall all the imperial copper conductors were tinned even though the insulation had been PVC for years. As I recall they only dropped the tinning when they moved to metric (and solid conductors for the smaller sizes).
