ELECTRICAL WIRING DEVICES 1.7
Share:
| Technical name ELECTROBLOCK 1.7 is a tool for architects and designers, electricians, and cost estimators working in Archicad®. The library is designed to provide professionals with the most convenient and efficient software solution for implementing project ideas related to electrical systems.
The library is designed to provide a range of benefits and improvements, such as design convenience and efficiency, accuracy and consistency through sets of Symbols that comply with standards and documentation requirements for electrical installations, as well as improved collaboration and data exchange among different project participants: architects, designers, electricians, cost estimators, and engineers can use the same library, which promotes more effective collaboration, eliminates inconsistencies, and ensures a single, unified source of data for the electrical systems within the project.
The history of the development and distribution of electric power across different countries has led to the emergence of many different standards for models of electrical wiring devices and their representation on architectural plans. GDLfragments has undertaken an effort to analyze and describe the full range of standards currently in use—both for product models and for drawing symbols—in order to identify and unify their common aspects. The Electrical Wiring Devices 1.7 library is presented in configurations that generalize these historically established differences in standards:
International standards from Europe and many other countries are used as a general reference.

Symbols in the context of the GDLfragments Wiring Devices 1.7 library are a group of .gsm files that the user assigns to each mechanism or device as a general symbol. Depending on the selected mechanism, the “Electrical Wiring Device” object places the corresponding symbols on the plan. Mechanisms can use two symbols: for surface-mounted, and for flush-mounted installations. The switching occurs automatically based on the selected installation type. For convenience, the Symbol Sets by kit and the symbol file index matching tables are provided below, which should be considered when configuring your own symbol sets.
The Wiring Devices 1.7 library provides a set of standard symbols based on the selected package. Users have the option to create custom symbols or symbol sets and link them either through a table or individually. It is highly recommended to familiarize oneself with and utilize the standard symbols, as well as to organize documentation according to established norms. Adhering to these standards during the design phase ensures clarity and consistency in electrical plans, enabling architects, electricians, engineers, and other professionals to easily understand and interpret the plans. This practice guarantees the correct installation and operation of electrical equipment.
The graphical symbols conform to the requirements of the IEC 60617 standard, “Graphical Symbols for Diagrams”, which is widely used in the European Construction Documentation System and in numerous other countries around the world.
Graphical symbols comply with the requirements of GOST 21.210—2014
