1. Conductor blowout analysis is conducted in accordance with thecriteria of the National Electric Safety Code (NESC).

2. Conductor blowout measurements are calculated at mid-span whereworst-case conductor displacement occurs.

3. Where total road ROW is less than 200' and poles are less than 15'from ROW line, TP-115B structures shall be installed.See Figure 3B for details.

4. Proposed conductor size is 336 kcmil ACSR, Linnet.
