What should NOT be done when attaching conductors to a mast?

• A. Use proper coupling materials
• B. Ensure clearances are maintained
• C. Attach where the coupling is below the last point of securement
• D. Install with adequate strength supports

Answer: (C)

When attaching conductors to a mast, it is crucial to adhere to proper installation practices to maintain safety and compliance with the NEC. One important aspect of this is the positioning of conductors in relation to the last point of securement. Attaching conductors where the coupling is below the last point of securement is not advisable because it can lead to excessive stress on the conductors and connections. This positioning may affect the integrity and reliability of the installation, as it does not provide adequate support and could result in sagging or damage to the conductors over time. Proper support and securement above the coupling point ensure that mechanical forces, such as tension from wind or weight from the conductors themselves, do not negatively impact the connection or lead to potential hazards. In contrast, using proper coupling materials, ensuring that clearances are maintained, and installing with adequate strength supports are all practices that align with safety and compliance regulations, promoting a secure and reliable electrical installation.
