Electrical schematic diagram of various layouts, such as panel board layout, terminal box /junction box layout, duct layout (useful at the time of erecting the machine or panel boards), termination of the cables on the machine layout, and other layouts are useful for the assembly of the electrical panel boards, and electrical assembly on the machines. Electrical control circuit diagrams deals with the logic interlock controls as per the design and operational requirements of the machine with safeties and I E rules/mandatory norms. Electrical power circuit diagrams deals with the power inputs to various electrical equipment /appliances, as per the design requirements of the machine, while fulfilling safety norms for the machine and equipment and to the people working on the machines.
