NESC
The NESC is revised every 5 years with the purpose of providing formal standards, safety-oriented work practices and practical guidance for the safeguarding of persons during the installation, operation, and maintenance of electrical/communication supply lines and equipment employed by utilities such as public or private electric supply companies, communications providers and railways. NESC rules contain the basic provisions, under specified conditions, that are considered necessary for the safeguarding of the public, utility workers (employees and contractors), and utility facilities.
