Our SM#160 bow thruster draws about 485 Amps when it is running. The exact power calculation is complicated because the voltage is not steady at 24 volts, but drops quickly, and significantly, under this load. The reason the wire looks undersized by standard calculations is that it operates on a very short duty cycle, so heating of the wire is minimal. If you were to try to push 500 Amps through that wire for an hour, you'd have a real problem.
