Nec 410.143(d)

Okay. I read the above section of the NEC and I still can't believe what I'm reading. It state's:

Secondary circuit outputs shall not be connected in parallel or in series.

Well if it's not connected in series and parallel then what configuration is used?
Is there some configuration that the college textbooks did'nt explain? What else could a circuit be if it's not series or parallel? A combination series-parallel circuit perhaps?

Context my friend, context.

410.143 is about transformers and (D) prohibits connecting two or more transformers in parallel to increase current or series to increase voltage.

That's why you need a diagram.
