Location of implementation for: <br />• GAP OF POLE-TOP GROUND <br />OR PHASE <br />~ Add'dional ~ <br />Vertical Spacing 18" <br />10' Wood <br />Crossarm <br />Neutral Wire <br />_S Wood <br />Figure 2: Typical Eagle-Safe three-phase pole configuration using a dropped 10-foot <br />crossarm creating a gap between the pole-top ground or phase and the phases on the <br />crossarm. <br />Dropping a crossarm an additional 27 inches may require shorter spans or taller poles to <br />maintain safety clearances, adding to the structures cost. A common alternative to <br />dropping the arm is to use a 10-foot crossarm and lowering the arm only an additional 12 <br />inches. This provides the recommended 60 inches of separation without using taller <br />poles and is the most economical method to raptor-proof a structure. <br />4.18-6 Revision Date: 2/11/05 <br />Revision No.: MR-70 <br />
