True or False: Failure of conductor insulation is a cause of failure in high-voltage and low-voltage electrical wiring.

The statement is true; failure of conductor insulation can indeed lead to failures in both high-voltage and low-voltage electrical wiring. Insulation serves a critical role in protecting conductors from environmental damage, electrical stress, and unintended contact with other conductive materials.

When insulation fails, it can create a direct path for electrical current to travel where it shouldn't, leading to short circuits, equipment damage, electrical fires, or even personal injury. This risk is present regardless of the voltage level, so insulation integrity is vital in all wiring systems. Therefore, indicating that failure of conductor insulation does not contribute to failures in electrical wiring would be inaccurate.

Understanding the importance of proper insulation and the potential consequences of its failure is essential for ensuring safe and reliable electrical installations.
