Elementary, pnaban. Inform webmaster at www.siemens.com about the broken link problem of www.sea.siemens.com/busway/product/bus-spec-instal

I don't think a utility co. would require for single-core cable different colors. Some utilities require for low-voltage three or four-core cable different color for cores. Usually medium voltage cable sheath [jacket] is red colored.

The electrons will be confused, and may decide not to flow.

Not a big deal at all...in offshore oil and gas facilities that i have worked on, all our single core cables have the same outer sheath colour...

I am not too worried about the electrons losing the directions, as we do not use DC for high voltage transmissions...AC causes no net movement for the electrons, they merely oscillate back and forth about an equilibrium point in response to the alternating electric field...
