In systems with ungrounded conductors, what is the voltage from each ungrounded conductor to the neutral?

In systems with ungrounded conductors, the usual voltage found between each ungrounded conductor and the neutral is typically 60 V. This is based on standard electrical systems, particularly in North America, where the common configuration for lighting and power circuits utilizes a voltage of 120/240 V.

In these systems, the ungrounded conductors are primarily at line voltage, which is often split into two phases. When considering one ungrounded conductor, it will show a voltage of 60 V when measured against a neutral point, as the neutral serves as a return path and is effectively at ground potential in these assessments. This structure ensures that the voltage remains manageable and conforms to safety and operational standards.

When examining the other provided options, the values are not representative of standard configurations in ungrounded conductor systems, which makes them less applicable in this context. Thus, identifying 60 V as the voltage from each ungrounded conductor to the neutral aligns with the established norms in electrical training and practice.
