What is one common cause of electrical faults?

One common cause of electrical faults is insulation failure due to age or damage. As electrical insulation ages, it can degrade due to factors such as heat, moisture, and mechanical stress, leading to cracks, breaks, or other forms of compromise. When insulation fails, it can result in shorts, ground faults, or unintended current pathways, which can create safety hazards and system failures. Understanding the importance of insulation integrity is crucial for maintaining electrical systems and preventing faults.

While other factors can contribute to electrical faults, they are often not direct causes in the same way that failed insulation can be. For instance, overheating of electrical components can indeed lead to faults, but it is frequently a consequence of other failures, such as inadequate insulation or poor circuit design, rather than an independent cause.
