Which of the following is NOT a recommended practice for circuit installations?

Mixing grounding conductors with power circuits is not recommended as a practice for circuit installations. Grounding conductors serve a specific purpose, which is to provide a safe path for electrical fault currents to reduce the risk of electrical shock and fire. When grounding conductors are improperly mixed with power circuits, it can lead to several issues, including potential safety hazards, interference with the effective operation of grounding systems, and non-compliance with electrical codes.

In contrast, using appropriately rated wiring for the load ensures that the wiring can handle the current without overheating, thereby preventing potential failures. Ensuring that junction boxes are accessible is crucial for maintenance and safety, allowing for easy access to electrical connections. Installing Ground Fault Circuit Interrupters (GFCIs) in wet locations is essential for protecting against electrical shock, as these devices are designed to cut off the electrical supply when a fault is detected. Each of these practices enhances the safety and reliability of electrical installations, while mixing grounding conducts with power circuits undermines these important objectives.
