Which of the following loads does not require a grounded conductor?

Question

Quizplus · Accepted Answer

A 2-wire, 240 volt load does not require a grounded conductor as it only requires two ungrounded conductors. Option A (2-wire, 120 volt) does not have a grounded conductor and is used for certain low-power devices, but generally, a grounded conductor is required for most 120 volt circuits. Option B (3-wire, 120/240 volt) does require a grounded conductor as it has both a 120 volt and 240 volt component. Therefore, the correct answer is Option C (2-wire, 240 volt).
