What is the function of the circuits in the three parts of the transformer?

1. On the diagram, at point A of the transformer, a black wire is connected to the terminal; at point B, one black wire and a yellow-green colored grounding wire are both connected to the terminal. What is the function of the wires at points A and B? Is the grounding wire at point B the one that must be connected to ground on the secondary side of the transformer? 2. Are the two wires at point C used to measure the current of the two motors?
1. The current transformer has S1 and S2 terminals; power enters at S1 and exits at S2, and S2 must be grounded, which is why there are two wires connected to S2 ； 2. The two wires at point C are indeed used to measure the total current in these two circuits
