Voltage Drop Calculation Report
Generated on May 15, 2025
Circuit Parameters
System Type: Single-Phase
Supply Voltage: 240 V
Load Current: 200 A
Circuit Distance: 150 ft
Conductor Material: Copper
Wire Size: 2/0 AWG
Power Factor: 0.95
Calculation Results
Voltage Drop: 5.89 V
Voltage Drop %: 2.45%
Voltage at Load: 234.11 V
Power Loss: 1178 W
Within Limits: Yes (≤3%)
Calculation Method
Formula Used:
Single-Phase: VD = 2 × I × R × L × PF
Where: VD = Voltage Drop, I = Current, R = Resistance, L = Length, PF = Power Factor
Code Compliance Notes
• NEC recommends maximum 3% voltage drop for branch circuits
• Total voltage drop (feeders + branch circuits) should not exceed 5%
• Voltage drop affects motor starting and equipment performance
• Consider load growth and future expansion when sizing conductors
