What is the correct sequence in hooking up the camlock connectors?

• A. Ground, neutral, then the phases
• B. Neutral, ground, then the phases
• C. Phases, ground, then neutral
• D. Ground, phases, then neutral

Answer: (A)

Grounding first is the main idea here. Establishing the protective earth path before anything else ensures the equipment’s enclosure is at earth potential and a fault can carry current to the ground, which helps any protective device trip quickly and safely. After the ground is secured, connect the neutral so the return path is in place, then finally connect the hot conductors to energize the circuit. This sequence minimizes shock risk because an ungrounded or live metal surface is not exposed while the system is still being wired. If you were to connect hot conductors before grounding, a fault could energize the enclosure without a reliable path to trip protection. If you connect neutral before grounding, you still risk unsafe conditions until the earth path is established.
