I been a while since I've done one of these,
Let me know if there is some thing I might have missed Or confused
208Y/120v system feed to a control / small power cabinet
3PH loads
4- Heater @ 18000 watts total or 18000 VA PF~1
1- Power supply @ 5000 watts or 5000 VA PF~1
8- 1/3Hp 208v motors @1.6 FLA +25% to 14A overall. (on VFD'S)
Single Phase Load
4 Circuits at 600 VA, Computer/ small fan, control power = 2400VA total
Calc.
All VA load
25400 VA /(208Volts *1.73) = 70.58 AMPS
+ motors 14 Amps + 84.6 Amps
84.6 A *1.25 + 105.73 Amp
Will install
{125A Breaker W/ #1 wire feed}
