For example,let’s calculate the wire size of a 100-meter-long copper wire for a single-phase circuit when it must supply 30 amps of current with a 10 V voltage drop allowed: A(mm²)=2 × 1.7241×10-8Ω·m × 100 m × 30 A/10 V× 1,000,000 ...
To calculate the wire size for a 3 phase electrical system, multiple the result for a single-phase supply by √3/2. How do I calculate AWG wire size? Here's how you calculate AWG (American Wire Gauge) from the diameter of a wire: Find the ratio (R) of the wire diameter to either...
