One Line or Single Line Electrical Diagrams

When ITU conducts an Arc Flash Analysis or Arc Hazard Study of your facility, our Professional Engineers will produce a One Line or Single Line Electrical Diagram of your electrical system. This exclusive drawing or drawing set will depict the the points involved in the electrical distribution of your power system and the single line representation of where each point is fed from and is connected to. The drawing will include the power utility transformer thru the main switch gear, distribution panels, and all electrical switch panels in your facility. The print will contain the basic circuit identification along with the arc flash energy, the fault currents, the flash protection boundaries, and the risk hazard category at each point on the drawing. This gives you the information as required by the NFPA 70E and OSHA guidelines. The drawing is a very useful tool for future electrical planning as well as everyday circuit identification and tracing as needed by electricians and maintenance operations and activities. This electrical drawing is presented to you as constructed during the arc flash analysis, and can be customized to your internal standards or needs by your drafting department.
