Ok I got this scenario 120/208V 3Φ 4 wire
Panel ----------------------------light---------------------light---------------------light
|------100 ft-----------------------|---------50 ft ----------|---------50 ft ----------|
------------------------------------- 8 A ---------------------- 8 A ---------------------- 8 A
And these are my calculations
Branch #1
VD = (√3/2 * K * load * length) / cmil
VD = (√3/2 * 12.9 * 24 *100) / 10380
VD = 2.58V
Voltage at load # 1 =117.42 V
VD% = 2.15%
Branch #2
VD = (√3/2 * K * load * length) / cmil
VD = (√3/2 * 12.9 * 16 *50) / 10380
VD = 0.86V
Voltage at load # 2 =116.56 V
VD% = 0.72%
Branch #3
VD = (√3/2 * K * load * lenght) / cmil
VD = (√3/2 * 12.9 * 8 *50) / 10380
VD = 0.43V
Voltage at load # 3 =116.13 V
VD% = 0.36%
Total Voltage Drop = 3.225%
i am in the right track
Best regards
