To open a circuit breaker, you typically move its handle or control mechanism to the OFF position. Based on the provided reference, this specific type uses a rotary handle.
Steps to Open the Circuit Breaker
According to the reference information, the process for opening this particular circuit breaker is straightforward:
- Locate the circuit breaker handle. It should be in the I (ON) position, indicating the circuit is currently closed and power is flowing.
- Turn the rotary handle counterclockwise.
- Continue turning until the handle reaches the O (OFF) position.
Turning the handle counterclockwise from the I (ON) position to the O (OFF) position effectively opens the circuit, stopping the flow of electricity.
Understanding the Positions
Circuit breakers often have markings to indicate their status.
| Position | Status | Action Implied |
|---|---|---|
| I (ON) | Closed Circuit | Power is flowing |
| O (OFF) | Open Circuit | Power flow is interrupted |
Note: The reference also mentions closing the circuit breaker involves turning the rotary handle clockwise from the O (OFF) position to the I (ON) position.
Always ensure you understand the specific type of circuit breaker you are operating, as mechanisms can vary. However, the fundamental concept of moving from an 'ON' to an 'OFF' position to open the circuit is standard.
