Final answer:
NM cables cannot be stapled on edge, as this could damage the insulation and the cables itself. They must be secured with proper staples or straps in accordance with the NEC. The correct answer is false.
Step-by-step explanation:
The student is asking whether it is true or false that NM (nonmetallic) cables can be stapled on edge. NM cables cannot be stapled on edge as it can potentially damage the cable and its insulation. Therefore, the correct answer to the student's question is: b. False
When it comes to NM cables, they should be secured and supported in accordance with the National Electrical Code (NEC). They are typically secured by staples or straps that are intended for cable support, ensuring the cables are not pinched or compressed. This assists in preventing physical damage.
Regarding the other questions provided as references, the query about high-voltage wires is false—they are not wrapped in insulating material; they are bare and held aloft by insulators. Tension is indeed a result of opposite forces in a connector, and in a circuit diagram, it is false that the voltage is the same at every point in a given wire.
