Verify Secure Connection and Prepare for Wiring

What happens here

Once the captive screws are manually tightened, perform a final visual inspection. Ensure that every screw head is completely flat against the breaker and that the breaker is perfectly touching the busbar. This confirms a great and secure electrical connection. Verify that the circuit breaker remains in the 'OFF' position for safety. The circuit breaker is now mechanically and electrically installed and ready for the load wiring (e.g., MC cable) to be connected to its terminals.

Goal: Ensure a perfect connection and readiness for final wiring.
