And when the (four foot) diameter wires melt because they couldn’t handle the amounts of power drawn by the ridiculously overpowered ship’s systems? Well, she and the crew’ll be right back in her element—eating freeze-dried synthetic rations, huddling around oxygen candles for heat in a battered, underlit cargo bay, and drifting slowly between planets at sublight speed. 
(Seriously, though, maybe they shouldn’t have the antimatter reactor plasma directly feeding the light bulbs and computer terminals. They might not explode so often.)
Funny thing is, anyone’s that’s used three-phase 220v in an industrial situation knows: the wires can be smaller in diameter due to the higher current.
Who knows, perhaps plasma conduits in their uninstalled state are just really thin wires of di-copper that vaporize when the power is applied the first time.
This (bolding mine) is the test. And I think Scotty could go more than a week. He’d grumble about the weird non-standard mods, but he’d keep it together for as much as two weeks. 
You mean those big glowy pipes leading outta the warp core? 
No silly, those are the primary reactant feeds! (at a 1:1 ratio, as everybody knows…it was a trick question on one of Weasley’s tests)
Now you’ve got me thinking about a show with a ship that’s having to deal with, say, four or five of their kids while they’re off somewhere.
The horizontal glowy pipes, not the vertical ones! Stay focused!
It’s GREEN!
Shiney!
Kirk and Mal look up at the imaginary sky, rolling their eyes. Then, they happen to catch a glance at each other’s hotness from the corner of their eyes …
Wow. That big chair really allows for some – interesting-- positions, doesn’t it?
