[ricicle]

No - the cable itself

 

[Adam_151]

Imperial cable of core diameter four tenths of an inch (approx 81mm² if I've pressed the right buttons on the calculator!) for each of the three phase conductors with a neutral half that size ?

Almost Adam - just your calcs wrong (.4 csa )

 

[Adam_151]

Almost Adam - just your calcs wrong (.4 csa )

I thought imperial cable sizes were given as diameter and not CSA? like 7/0.029 is 7 strands of 0.029" dia which works out about 2.9mm² CSA

Or were both naming conventions in use at different times?

Anyway, that means then that the cable is about 250mm² as opposed to 81mm² what would use that much power all those years ago, something quintessentially British I suspect at least....

Thats just one of fourteen that size.

As for the usage - machine heating and hydraulic power
