Common Mistakes to Avoid

1. Incorrect Wiring

Reason: Connecting wires to the wrong terminals can lead to malfunctioning outlets, electrical shocks, or even fires.
Solution: Double-check the wiring diagram and ensure that the hot, neutral, and ground wires are connected to their respective terminals.

2. Ignoring Grounding

Reason: Failing to properly ground the outlet leaves electrical appliances and users vulnerable to electric shocks.
Solution: Always connect the ground wire to the grounding terminal, ensuring a safe path for stray electricity.

FAQs
