Posted By Topic: 3C NS PEC submain

Mar 26 2018 12:41

In a single phase PEC submain comprised of three cores plus screen ... with red=phase, white=PEC(GY), and screen=neutral ... is there any advantage sleaving the blue to black as a neutral conductor? Will removing the flow of current in the screen result in a cooler cable?

I would be using the screen as earth, and sleeve the blue as neutral.
As originally intended for 3ph use, the screen would have been earth in any case.
