Basic Requirements for Electrical Installations

摘要

The rules in Art 110 aren't difficult to interpret, so why are Code violations so common? Article 110 contains some of the most important but neglected parts of the Code. It also answers these basic questions: 1. How should conductors be terminated? 2. What kinds of warnings, markings, and identification does an installation require? 3. How much working clearance is enough? It also covers the general requirements for the examination and approval, installation and use, access to, and spaces about electrical equipment. In addition, it lists general requirements for enclosures intended for personnel entry (manholes, vaults, and tunnels).
