WitrynaTo apply a manual derating, divide the load by the derating factor from NEC, and enter the new load value in the calculator. Voltage drop calculation: The single phase AC voltage drop is calculated as: \(V_{d1\phi}=\dfrac{I L (2 Z_c)}{1000}\) where I is the load current, L is the distance, and \(Z_c\) is the cable impedance in O/km. WitrynaDetermine the load factor by observing the load factor chart below. Ex. Assume that the leg angle will be 60°. The load factor for 60° from the load factor chart is 1.154. Multiply the load factor times the minimum weight to be supported by the leg, i.e. 1000 pounds times 1.154=1154 pounds. The rated sling capacity needed is then 2308 (1154× ...
