According to the IEC 309 clocking system, where is the keyway positioned for all female connectors and receptacles?

• A. 12:00
• B. 3:00
• C. 6:00
• D. 9:00

Answer: (C)

In the IEC 309 clocking system, the keyway is designed to ensure proper alignment and safety in the connection of electrical equipment. For all female connectors and receptacles, the keyway is systematically positioned at the 6:00 position. This standardization allows for uniformity across different devices, making it easier for users to connect and disconnect equipment without the risk of misalignment or damage. The choice of the 6:00 position is particularly important because it establishes a consistent reference point, ensuring that connectors can only be inserted in the correct orientation. This design helps to prevent user errors during connection and also enhances safety by reducing the likelihood of electrical accidents. By adhering to the IEC 309 standard, manufacturers and technicians can ensure interoperability between devices while maintaining high safety standards.
