How do setup the center tapped transformer provided for 120VAC on the primary and 30VAC on the secondary?

I think the center tap on the transformers are always 1/2 the whole transformer. You could use two different transformers to do effectively the same thing.

not exactly what I mean, I just want to take the center tapped transformer that comes with circuit lab and make it give me 120VAC on the primary and 30VAC on the secondary, I need to know how to set the parameters for this part to give me this functionality.

@Big-Chuck,

The CL transformer symbol can be confusing.

The series of circuits: below attempt to provide help on understanding how to use and understand the transformer symbol in CL.
