Concept

In a 3-wire DC system, the neutral is at the midpoint between the two outer conductors. Therefore, the voltage between each outer conductor and the neutral is:

\(V_{outer-neutral}={V_{outer-outer}\over 2}\)

Calculation

Given the voltage between the two outer conductors is given as 300V.

\(V_{outer-neutral}={300\over 2}=150\space V\)
