Question 129Electricity & Electronics - 1st Asst/Chief

The correct answer is D) fixed contact. The fixed contact is the stationary part of an electrical circuit that remains in a fixed position, while the moving contact is the part that moves to make or break the connection. In the illustration EL-0033, the component labeled "C" represents the fixed contact, which is the stationary part of the electrical circuit that the moving contact connects to. The other options are incorrect because: A) a trip bar is a mechanical device that trips a circuit breaker, B) a connection terminal is where wires are connected, and C) the moving contact is the part that moves to make or break the connection, which is a different component from the fixed contact.
