What should be checked before testing for ground in an AC circuit?

• A. Resistor resistance
• B. All connections are secure
• C. Voltage levels
• D. Insulation integrity

Answer: (B)

Ensuring that all connections are secure is critical before testing for ground in an AC circuit. If the connections are loose or improperly connected, it can lead to inaccurate readings and unsafe conditions. Secure connections help to ensure that the circuit operates correctly and that the ground reference is stable. This is essential for safety and reliability, as improper grounding can cause electric shock hazards or equipment failure. While checking resistor resistance, voltage levels, and insulation integrity are important practices in maintaining AC circuits, they do not directly influence the initial step of ensuring a secure connection before grounding tests. A secure connection guarantees that the circuit is complete and that the conditions for testing ground are optimal.
