Which of the following is a requirement for the conductor insulation testing procedure as per Wendy's specifications?

The requirement that the resistance must be higher than 1 mega-ohm is crucial for conductor insulation testing. This threshold ensures that the insulation integrity is sufficient to prevent current leakage, which could pose safety hazards or lead to equipment failure.

In practice, a minimum resistance value of 1 mega-ohm indicates that the insulation is in good condition, helping to protect both the electrical system and any personnel who may come into contact with the equipment. Values below this mark can suggest degradation of insulation material or potential failures, necessitating further investigation or remediation before the system can be safely operational.

While other options may contain elements relevant to electrical work, they do not specifically address the required resistance level that ensures safety and functionality as highlighted in the specifications.
