2-plug VS 3-plug power cords

When choosing between 2 Pin VS 3 Pin Plug Inserts, the key differences lie in safety and application scenarios.

2-plug power cord

2-Plug Power Cord: Consists of two wires – fire (L) and neutral (N). This power cord has no ground wire and is typically used for low-power devices.

It is mainly used for low-power devices that do not require grounding protection, such as some household appliances, lamps, and power tools.

If there is an electrical fault in the metal casing of the equipment, it may become electrically charged, leading to electric shock and other safety hazards.

3-Plug Power Cord

3-Plug Power Cord: In addition to the fire and neutral wires, a ground wire (G) is added. The grounding wire is intended to provide electrical safety protection for the equipment, preventing electric shock and other hazards due to equipment malfunction.Provides grounding protection, especially for high-power equipment or where the enclosure of the electrical equipment is metal. Examples include TVs, refrigerators, and electric cookers.
The grounding wire can effectively conduct the current charged by the equipment shell into the ground, thus avoiding personnel electrocution. Even if there is a leakage or short circuit in the equipment, the grounding wire can ensure safety.
This design complies with most national safety standards for high power electrical equipment (e.g., NEMA 5-15P in the U.S., CEE 7/7 in Europe, etc.).
