Which action helps prevent crossarm misalignment when moving the outside phases?

• A. Moving the outside phases in sync
• B. Moving only one phase at a time
• C. Dropping the transformer
• D. Using a longer boom

Answer: (A)

Synchronizing the movement of the outside conductors keeps the crossarm and insulators in their proper orientation. When both outer phases are moved together, the forces on the crossarm stay balanced, so the arm doesn’t twist or tilt and the insulators stay aligned with the hardware. Moving them one at a time can introduce unequal loads, causing the crossarm to rotate or become misaligned and potentially creating gaps or binding with adjacent hardware. Dropping the transformer isn’t related to keeping the crossarm aligned, and using a longer boom doesn’t address the alignment issue. Keeping the outside phases in sync is the reliable way to prevent misalignment during the move.
