Electrical power symbols are used in engineering diagrams to represent components such as motors, generators and electrical connections. These standardised symbols allow engineers to interpret and design electrical systems efficiently.
This page provides a reference for commonly used electrical symbols in power and control diagrams based on recognised engineering standards.
Electrical symbols are graphical representations of electrical components used in schematic and wiring diagrams. They provide a universal language for engineers to communicate circuit design and system functionality.
The symbols shown below are generally based on BS 7845:1996 , BS 3939 and BS EN 60617
The diagrams are produced using symbols .. The number of symbols are very large and
BS EN 60617 includes many fields from power generation to solid state electronics.
The symbols below are just a selection related to the fields related to general engineering provided as a
general guide/ For details showing proportions and sizes reference to the standards is necessary
See related pages for additional engineering symbols including process flow diagrams, piping symbols and surface finish symbols used in technical drawings.
