Final answer:

Both Technician A and Technician B are correct in their statements regarding the wiring of main service panels.


Explanation:

Technician A is correct because the main service panel is indeed usually bonded to the grounding bus, ensuring safety by providing a path for fault currents to ground.

Technician B is also correct. In a normal home installation, the neutral wire carries the return current, and ideally, no current should flow through it, as it is at the same potential as the ground.

Therefore, Both Technician A and Technician B are correct regarding the wiring of main service panels.
