Where is the first crossarm gain cut from the top of the pole?

The correct measurement for the first crossarm gain cut from the top of the pole is established at 12 inches. This is a standard practice in pole installation where the crossarm gains, which are notches cut into the pole to support crossarms, are placed at a consistent height to ensure structural integrity and optimal performance of the pole in supporting wires or cables.

By setting the gain cut at 12 inches, it factors in both the effective height for the crossarm connection and the stability needed to withstand various environmental conditions. This standardization is critical for ensuring that poles are set uniformly across installations, which strengthens the reliability of the overall network supported by these poles. The other measurements, while they may relate to different construction or installation practices, do not align with this typical 12-inch standard for crossarm gain cuts.
