What is the voltage between either of the non-wild leg hot lines and neutral in a 230-volt grounded delta system?

In a 230-volt grounded delta system, the voltage between either of the non-wild leg hot lines and neutral is indeed 115 volts. This is because of how the delta configuration operates and how the neutral is established.

In a grounded delta system, one of the phases is connected to ground, which can be thought of as providing a reference point. Because the total system voltage is 230 volts, each phase is at 230 volts relative to the ground. However, the grounded phase (or neutral reference) effectively divides the voltage seen by the non-grounded phases. Since the voltage in a delta system is distributed equally, the voltage between any non-grounded leg (also known as the hot leg) and the grounded leg (neutral) is half the total line-to-line voltage of 230 volts.

This division results in a voltage of 115 volts between each hot line and neutral, which aligns with standard practices for household and light commercial electrical distribution in many systems. Thus, this item illustrates the relationship between voltage levels in certain configurations, emphasizing the underlying principles of wiring in such electrical systems.
