Are you ready to become a lineworker? Heard about the National Electrical Safety Code but not sure what it is and why it applies to electrical lineworkers? Let’s look at the NESC and what you should know about it to be a successful electrical lineworker.

What is the National Electrical Safety Code?

The National Electrical Safety Code (NESC) is published by the Institute of Electrical and Electronics Engineers. This safety standard covers basic provisions for safely installing, operating, and maintaining electrical conductors and equipment. This also includes rules for construction, maintenance, and the operation of electrical supply and the electrical lines, telephone, Cable TV, and railroad signal systems.

For electrical lineworkers, the NESC is a safety standard for safe installation, operation and maintenance of electric power utilities, substations, and power lines both overhead and underground. The NESC also sets the minimum safety standards for power companies and electric utility companies to properly inspect their power lines, maintain power lines, to trim trees near power lines and prevent downed power lines causing electric shock injuries.

What is the National Electrical Code or NFPA 70?

The National Electrical Code (NEC) is a U.S. standard for safe installation of electrical wiring and equipment. It is published by the National Fire Protection Association (NFPA). NEC use is commonly mandated by state and local law.


The National Electrical Safety Code and National Electrical Code both safeguard electrical installation. They overlap regarding property and premises wiring systems. Knowing both standards can help protect lives and property.

Both codes are governed by the American National Standards Institute (ANSI). However, they are different and serve different purposes. The difference between the National Electrical Code and the National Electrical Safety Code is that the NEC focuses on electrical systems within homes and business, whereas the NESC focuses on large electrical power systems that supply power to those homes and businesses. Fortunately, they both work together to keep everyone safe that is exposed to electrical wiring, systems, and equipment.
