How do you calculate load carrying capacity of a cable?
How do you calculate load carrying capacity of a cable?
Cable Capacity
- 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.
What is current carrying capacity of a wire?
Current carrying capacity of a wire is defined as how much load a conductor can carry (In amperage). When the current flows through the conductor a certain level of heat generates which can further increase up to the melting temperature of the insulation or insulating material.
