The Different Types of Locking Extension Cords and Their Uses

Locking extension cords are used to provide electrical power to devices and equipment. They are designed to stay securely in place and prevent accidental disconnection. Here are some of the different types of locking extension cords and their uses:

1. NEMA L5-20: This is a 20-amp locking extension cord with a twist-lock connector. It is commonly used with industrial equipment and appliances that require a higher amperage rating.

2. NEMA L6-30: This is a 30-amp locking extension cord with a twist-lock connector. It is commonly used with large machinery and equipment, such as air compressors, welders, and generators.

3. NEMA L14-30: This is a 30-amp locking extension cord with a twist-lock connector that has four prongs. It is commonly used with generators and other equipment that require a high amperage rating and a neutral connection.

4. NEMA L15-30: This is a 30-amp locking extension cord with a twist-lock connector that has three-phase power. It is commonly used with industrial equipment that requires three-phase power.

5. NEMA L5-30: This is a 30-amp locking extension cord with a twist-lock connector. It is commonly used with industrial equipment, such as power tools, pumps, and compressors.

6. NEMA L6-20: This is a 20-amp locking extension cord with a twist-lock connector. It is commonly used with industrial equipment that requires a higher amperage rating.

7. NEMA L21-20: This is a 20-amp locking extension cord with a twist-lock connector that has three-phase power. It is commonly used with industrial equipment that requires three-phase power.

In summary, locking extension cords come in various types with different amperage ratings, twist-lock connectors, and three-phase power capabilities. They are commonly used with industrial equipment and appliances that require a high amperage rating and a secure connection. It is important to choose the right type of locking extension cord that meets the requirements of your equipment and ensures safe and reliable electrical power.
