This can cost valuable resources and time.

If this happens, you have to source for another professional to figure out what the problem is, and then fix it. It can also result in the development of a new issue and can bring done the whole electrical system, putting occupants of the building at risk of having elevators and HVAC units become useless. Errant sparks and electrical fires become major risks.
Inability of the maintenance worker to appropriately read electrical prints can bring frustrations. This means understanding locations of circuits and outlets and the correlation that exists. In diagnosing problems and ensuring that all components are working properly, maintenance workers are required to understand the print down to the last detail in order to follow the instructions exactly and proficiently. Maintenance work may involve fixing or replacing major parts, motors, control systems, light fixtures, and other items in the electrical system. It can be difficult for a maintenance worker to understand where different components are located, especially in large buildings and some of the affected components are difficult to reach. Maintaining electrical equipment and systems involves troubleshooting problems and repairing broken equipment. Installation of electronic systems is less complicated than the maintenance part of it.

Why Maintenance Workers Need to Know How to Read Blueprints As such, interpreting the plans and understanding what the prints are saying can be difficult to those who lack comprehensive print reading training. To read electrical blueprints one must understand the flow of the circuit, identify critical nodes, understand Ohm’s Law, and have a deep comprehension of the National Electrical Code. You may know that the inverter is represented by a triangular symbol but if you don’t know what follows after that, you don’t really have an idea of how the system is structured.ĭetails like wire or cable specifications belong elsewhere in a separate documentation. It can be easy to look up the diagram but wrapping your head around the actual meaning is a little harder. The symbols do not look anything like the components they represent and the lines may not resemble the actual physical layout of the components. In some cases, a line can run between components without being connected to any of the components. Each electronic component has a symbol and the connection between specific component terminals is represented by the lines. Many individuals find it difficult to read and understand electrical blueprints, mainly because the prints just show lines and symbols. Reading Electrical Prints Can Be Difficult Should there be a problem with the building’s electrical system, the electrical print will help maintenance technicians to troubleshoot and fix the problem. These components include wires, light switches, receptacles, wires, light fixtures and any other stuff that will be electrically powered. The print is like a simple roadmap that shows where components are located, the connections, and the wire paths between the components. Tags: electrical blueprints, how to read electrical blueprintsĪn electrical print is a technical drawing that shows how the electrical system in a building is going to be constructed and how electrical components will be connected to get a certain function.
