Original Version
Rule 46
| 46 | Vertical Strength Requirements |
In computing vertical strength requirements the loads upon poles, towers, foundations, crossarms, pins, insulators and conductor fastenings shall be their own weight plus the superimposed weight which they support, including that of wires and cables under the loading conditions of Rule 43 plus that which may be added by difference in elevation of supports. The resultant of vertical and transverse loadings on conductors shall be used in determining the allowable and working tensions or sags in accordance with Rule 43 . In addition to the above a vertical load of 200 pounds at the outer pin position shall be included in computing the vertical loads on all crossarms. All members of structures shall be constructed to withstand vertical loads as specified above with safety factors at least equal to those specified in Rule 44. |

Final Version
Rule 46
| 46 | Vertical Strength Requirements |
In computing vertical strength requirements, the loads upon Lines (See Rule 22.1) shall be their own weight plus the vertical loads which they support under the conditions of Rule 43, together with the effect of any difference in elevation of supports. On structures with crossarms or guard arms, the vertical loads on the structure shall include a load of 300 lbs. at one end of one of the arms. Safety factors shall apply as specified in Rule 44. |
