HOW TO CALCULATE THE SIZE OF CABLE COPPER & ALUMINIUM
Answer Posted / himadri nayak
Copper Wire
Single Phase/Circuit
Voltage 240
Power(W) 1000
Power Factor 0.8
Resistivity(at 15 c) 1.72E-08
Tempertature 35 C
Resistivity 3.096E-08(for copper)
Length(m) 300(phase+neutral)
Cross section(m2) 0.000006
Resistance 1.55
Load 5.21
Voltage drop 8.06
Percentage 3.36(Do not go above 3 %)
Actual voltage 236.64
Actual Current 5.28
This is a sample of how to calculate wire size for single phase copper wire. If you want contact me for the excel sheet for copper/Al, 3phase/1 phase calculation.
