We had several 400-amp three-phase cables for shore power on my submarine. As I recall, each cable weighed about 10 pounds per foot. It took a working party to move them.
At first, I read that as “for short power”.
Sounds about right. 400A requires 600 kcmil copper (1" diameter) which is about 3 pounds per foot - so 9 pounds just for the main conductors. Add is a safety ground, insulation (what voltage was that at?), and protective cladding and you’re likely over 10 pounds.
Glad my memory checks out! It was 450 VAC.
Well I don’t know what to tell you; a search on 400 amp jumper cables returns plenty of examples that are nowhere near being foot-thick.
The double tick " is inches (or seconds if you are talking lat/lon)
So 1 inch diameter cable.

The shore power cables being discussed each contained three (3) 400-amp conductors to carry three-phase AC current. Each conductor was about 1” (one inch) in diameter. The whole cable weighed about 10 pounds per linear foot of cable length (so 10 feet of cable weighed about 100 pounds).
Nobody said the cables were a foot thick. With the insulation and protective cladding, the whole cable was actually about 3-4 inches in diameter.
Sorry; my vision is getting THAT bad.
“Forget this! Fuck the napkin!”
“Aww, the oceanic crust and the continental crust are getting married!”
I’m thinking about the tsunami it’ll trigger if their lifting tackle parts and the crust retreats to its resting state almost instantly.
Gonna be epic. Epic fail.
And so it was that the one ring came back to the surface once more, and the cycle began anew.
Who says geology is not a practical science?
Data: I know of no one who said that, Professor.
Fuck
You up for another trip to Mt Doom?
This time I’ll take the bus.
Maybe take an eagle…

Yeah, definitely shades of LotR.
