Twin wire neutral

neutralpower-engineering

I work in the power distribution industry and recently came across a 3-phase LV circuit with "twin-wired neutral" (i.e. two neutral cables inter-winded, therefore five cables total). What would be the point of such a neutral configuration? Would this be to carry more current due to neutral currents/unbalanced phases?

Cheers!

I think you are right, probably is to handle more current due to unbalance. Neutral cable's section for distribution transformer, should be the same as the phase conductor.
