The 3 indicates RYB and .5 Neutral. In normal conditions,
power supplied is balanced. So, no neutral current flows.
But in case of small unbalanced condtions, low amount of
neutral current has been found and hence to provide the
path for it, neutral wire is provided with half of the
cross section that of phase.

What are stable systems?
