What is so cord?

SO cord, also known as service cord or portable cord, is a type of electrical cable used for temporary power supply in industrial, commercial, and residential settings. It is flexible, durable, and capable of withstanding harsh conditions, making it suitable for various applications.

Key features of SO cord include:

1. Conductors: SO cord typically consists of multiple stranded copper conductors, which provide flexibility and enhance electrical conductivity.

2. Insulation: The conductors are insulated with a high-quality thermoset material, usually ethylene propylene diene monomer (EPDM) rubber. EPDM offers excellent resistance to abrasion, chemicals, oils, and extreme temperatures.

3. Jacket: The insulation is protected by a sturdy and heat-resistant jacket, typically made of chlorinated polyethylene (CPE). This jacket provides further resistance to water, sunlight, and impact damage.

4. Voltage and Capacity: SO cord is available in various voltages and capacities to suit different power requirements. Common options include 120V, 208V, 240V, and 480V, with amp ratings ranging from 10A to 100A or higher.

5. Color Coding: To easily identify different conductors, SO cord usually follows a color-coded system. The standard color code includes black for hot conductors, white or gray for neutral conductors, and green for grounding conductors.

6. Flexibility: The design and construction of SO cord allow for easy bending, installation, and movement, making it ideal for temporary power supply in construction sites, concerts, outdoor events, and temporary installations.

7. Compliance: SO cord is manufactured to meet various industry standards and safety regulations, such as those set by the National Electrical Code (NEC) in the United States.

When using SO cord, it is essential to follow proper installation practices, including keeping it away from sharp objects, excessive heat sources, and heavy traffic areas to prevent damage.

Overall, SO cord provides a reliable and versatile means of temporary power distribution, offering the flexibility and durability needed for demanding environments.
