What is one reason why regular inspection of insulation is vital?

Regular inspection of insulation is vital primarily to monitor for visible signs of damage. Insulation plays a crucial role in maintaining energy efficiency and safety in electrical systems. Over time, insulation can be subject to wear and tear due to environmental factors, physical damage, or degradation from heat and moisture.

By conducting routine inspections, technicians can identify issues such as cracks, fraying, or discolouration that signal compromised insulation. If these signs are left unaddressed, they can lead to reduced insulation effectiveness, which could result in energy loss, overheating, or even electrical failures. Detecting damage early ensures that appropriate measures can be taken to repair or replace the insulation, maintaining the overall integrity and safety of the system.

While the other options touch on important aspects of insulation maintenance, the core reason for regular inspections centers on identifying damage that could impact performance and safety.
