Step 1: Single Line Diagram

 

 

 

 

 

 

 

NFPA 70E requires up-to-date single line diagrams. This information is essential for documenting, troubleshooting and communicating information about your power systems. To meet this requirement, we can conduct a comprehensive site survey that will be used to update your existing single line diagrams or complete any unfinished electrical system drawings.

NFPA 70E (2015)

205.2: A single-line diagram, where provided for the electrical system, shall be maintained in a legible condition and shall be kept current.

 

Locating Sources. Up-to-date single-line drawings shall be considered a primary reference source for such information. When up-to-date drawings are not available, the employer shall be responsible for ensuring that an equally effective means of locating all sources of energy is employed.”
