Ok, probably a simple answer, or maybe not but let me ask anyhow.
On a typical 3-phase, 4-wire, 480/277v system with a 100A rated panelboard and a 100A rated main circuit breaker. The panelboard is used for lighting load operating at 480V.
The lights are single phase, 480V.
The connected load between phases A and B is 40A
The connected load between phases A and C is 30A
The connected load between phases B and C is 30A
What would the current be on the conductors supplying power to the panelboard?
In other words with the above connected loads...
A phase would draw _____ amps?
B phase would draw _____ amps?
C phase would draw _____ amps?
Is there a simple formula to calculate the individual currents on each phase?
