Which of the following is a component of a successful repair on a live main?

A successful repair on a live main relies heavily on the competency and preparedness of the individuals involved in the operation. Properly training personnel ensures that they have the necessary knowledge and skills to handle repairs safely and effectively. Trained personnel understand the intricacies of working under pressure, following safety protocols, and employing the correct techniques and tools for the repair job.

In contrast, using outdated methods, ignoring safety protocols, or employing inadequate tools could lead to hazardous situations, ineffective repairs, or even failures that can result in further damage or injury. Therefore, the emphasis on properly trained personnel is crucial in ensuring the repair is conducted efficiently, safely, and in compliance with industry standards.
