What should be done regarding service conductors that travel horizontally within 3 ft of accessible surfaces?

Service conductors that travel horizontally close to accessible surfaces must maintain a certain vertical clearance to ensure safety and compliance with the National Electrical Code (NEC). This requirement is in place to prevent accidental contact with the conductors, which could pose a risk of electric shock. Keeping the vertical clearance helps ensure that the conductors are not accessible to individuals in normal circumstances, reducing the likelihood of an unsafe interaction.

In the context of the NEC, service conductors must adhere to specific height guidelines that are established to protect both people and property. If the conductors are too low, they could become a hazard, particularly in locations where people frequently pass or work. Therefore, maintaining the proper vertical clearance is essential for ensuring the safety of the installation and the code's compliance.

The other options do not specifically address the requirement for vertical clearance in this context. Lowering the conductors might not always be feasible or safe, insulating them is not the primary concern in this case, and stating that they do not need any special treatment contradicts the NEC's safety standards. Ensuring adequate vertical clearance is the best practice for protecting individuals from potential electrical hazards.
