HELP with electrical substation

[anagerlo]

Hi, I'm writing to ask how it's done.

This is the circuit I made:

and this is the teacher's:

I don't know how to do this:

nor this one:

I put 3 switches but in theory, I would have to configure those 63A, this would represent a board. On the other hand, I don't know how to do this:

• the "green box" that encloses the 3 variable resistors.
  
  I attach my work and the teacher's pdf.
  
  Thanks in advance, I look forward to your responses
