Heating element power controller max voltage - Star configuration

[PreLC]

Hello PLCs.Net!

We have 3 elements in a star configuration, and each of the elements are rated for 20kW 120V - This is all I know about the heaters so far.
The limiting voltage on the power controller is 208V, 167A and 60kW.

Can someone show me the math involved here? Do the numbers seem correct?

Thanks!

Not sure what you are asking,


208v/1.732(square root of 3)for star connection = 120v phase to star point
Simple ohms law will verify the current
