What is the nest wiring diagram for a 3-wire system?

The wiring diagram for a 3-wire system typically includes a hot wire (black), a neutral wire (white), and a ground wire (green or bare copper). The hot wire carries the electrical current, the neutral wire completes the circuit, and the ground wire provides safety by grounding excess electricity. It is important to follow the specific wiring instructions for your particular system to ensure proper installation and safety.
