Notes:
- Minimum 50' pole height.
- Engineer must specify the size & number of down guys and anchors depending on conductor design tension, line angle, available down guy lead and span length. Refer to T&D Guideline 4-6 and Compatible Unit Sections A and G.
- Crossarms to be set to split the angle in the line. Guy should be set in the plane of the crossarm if possible.
- This assembly is intended for primary conductors with a maximum working tension of 2,500 lb/Ø or less. For deadending conductors with a maximum working tension between 2,500 lb/Ø and 4,000 lb/Ø refer to Assembly Unit 12F392.
- New overhead double circuit construction is allowed in rural areas only. Refer to T&D Guideline 4-23-7.0 — Design Practices for Constructing Double Circuit Lines.
