Mell How do you calculate the current carrying capacity of copper cables in sq mm?
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 the current carrying capacity of 120 sq mm copper cable?
Current carrying capacity of 305A.
What is the current carrying capacity of 4 sq mm copper wire?
An electrician commonly used “formula”: as long as the copper wire, cross-sectional area per square millimeter can be safely through the rated current of 4–5A; 220V in single-phase circuit, power per 1KW, the current is about 4.5A; in 380V three-phase balanced circuit, power per 1KW, the current is about 2A.
What current can a 10mm cable carry?
A 10mm cable can carry between 40 and 70 amps of current. The conductor and ambient temperature play a large factor in the load capacity and the safety of the wiring. A wire that has a sheathed or armored thermoplastic outer coating is able to conduct a greater load than one without.
