- For Cu Wire Current Capacity (Up to 30 Sq.mm) = 6X Size of Wire in Sq.mm. Ex. ...
- For Cable Current Capacity = 4X Size of Cable in Sq.mm, Ex. For 2.5 Sq.mm = 4×2.5 = 9 Amp.
- Nomenclature for cable Rating = Uo/U.
- where Uo = Phase-Ground Voltage, U = Phase-Phase Voltage, Um = Highest Permissible Voltage.
How do you calculate the current carrying capacity of a wire?
How is current carrying capacity calculated?The formula for calculating current carrying capacity is:I = permissible current rating.∆Φ = Conductor temperature rise in (K)R= Alternating current resistance per unit length of the conductor at maximum operating temperature (Ω/m)More items...
