Good Day,
Is it electrically correct (in terms of wiring standards) to use the shield wire in a cable as Ground(-).

There may be issues with ampacity and voltage drop in the event of a ground fault.

In case of single core power cables, it is also a practice to earth the shield wire only at one end to avoid derating the cable while sizing.
Shield wire, in either of the above cases, may help clear the cable phase-to-earth fault faster but that is only incidental.
The shield wire is not considered in the Earth grid sizing calculations.

Yeah, but if he's talking RS-232 - give it a shot. It's done all the time.
