What tests must be performed on each electrical circuit after installation of wiring?

The requirement to perform continuity, ground, and insulation resistance to ground tests on each electrical circuit after installation of wiring is fundamental to ensuring the safety and functionality of the electrical system.

Continuity testing verifies that the electrical connections are complete throughout the circuit. This is crucial for ensuring that the circuit can deliver power as intended without any interruptions due to poor connections or broken wires.

Ground testing is essential for safety. It ensures that the grounding system is correctly installed and functioning, which protects both personnel and equipment from electrical faults by providing a safe path for fault current to travel.

Insulation resistance testing to ground assesses the integrity of the insulation materials used in the wiring. This test checks for any potential leakage paths to ground, which could not only lead to equipment failure but also create hazardous conditions. High insulation resistance indicates that the wiring is properly insulated and there are no breakdowns that could lead to shorts or shocks.

The combination of these three tests provides comprehensive assurance that the electrical system is safe, reliable, and ready for operation, making this answer the most appropriate choice for the question.
