Which of the following is true about the installation of service conductors?

The installation of service conductors must use proper fittings for attachment to ensure safety, compliance with the National Electrical Code (NEC), and the structural integrity of the installation. Proper fittings are crucial because they provide secure connections that help prevent mechanical damage and degradation over time. Using the correct type of fittings also ensures that the conductors are adequately protected from environmental factors and properly grounded, reducing the risk of electrical faults and hazards.

Furthermore, adherence to these requirements correlates with maintaining a safe work environment and minimizing the likelihood of electrical accidents. The overall goal is to ensure the reliability of the electrical system while upholding safety standards as stipulated by the NEC. The other options provide guidelines that are not accurate or do not address the necessary safety measures required for a proper installation.
