Self-Inspection Checklist

Guidelines: This checklist covers regulations issued by the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) under the general industry standards subpart S 29 CFR 1910.305 and the construction standards 29 CFR 1926.405 and 1926.441. It applies to all electrical use systems. This checklist does not cover installations in ships, watercraft, railway rolling stock, aircraft, or automotive vehicles other than mobile homes and recreational vehicles. In addition, this checklist does not apply to conductors that are an integral part of factory assembled equipment. The regulations cited apply only to private employers and their employees, unless adopted by a State agency and applied to other groups such as public employees.

check mark symbol Questions marked with this symbol may require the help of an outside expert.

Definitions of terms in bold type are provided at the end of the checklist.

This checklist does not address regulations dealing with open wiring on insulators, pull and junction boxes for systems over 600 volts, portable cables over 600 volts, transformers, and capacitors. If these conditions are encountered, consult the OSHA regulations.
