Question

A conduction with a white insulation may be used as an ungrounded circuit conductor____. The conductor is contained in a cable.

I. if used for a 12-volt door chime system wiring.
II. if marked with black tape where visible or accessible and used to connect a 240-V pump
III. if marked with red tape where visible or accessible and used for a traveler from a 3-way
IV. if marked with blue tape where visible or accessible and used to feed the hot to a switch

Answer 1

A conductor with white insulation may be used as an ungrounded circuit conductor if it is marked with black tape where visible or accessible and used to connect a 240-V pump. The other options mentioned in the question are not correct.

Step-by-step explanation:

This allows the white insulation to be identified as a hot wire. The other options mentioned in the question, such as using red tape for a traveler from a 3-way switch or using blue tape to feed the hot to a switch, are not correct. These color markings are not standard for identifying a white-insulated conductor as a hot wire. Therefore, the correct answer is option II: if the white insulation is marked with black tape where visible or accessible and used to connect a 240-V pump.
