Overview of electrical CAD drawing standards

Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service. If there is no terminal designation assigned by the manufacturer to the device, arbitrary terminal designations shall be assigned and shall be explained in the table or in referenced supporting documents.

Connection diagrams, tables and lists IEC EN series Open data communication in building automation, controls and building management – Home and building electronic system – Part 1: At the IEC Function-oriented of the normative documents listed below.

Units —A1 and —A2 are provided with socket outlets whereas unit —A3 is provided with non-removable cables —W1 and isc, each ending with a plug, —X1 and —X2 respectively.

This part of IEC provides rules and guidelines for the classification of documents based on their characteristic content of information. Classification of objects and codes for classes. The number of cores of a cable is noted in a column, adjacent to the cable number and the spare cores in the last column on the same line. Cable diagrams, tables and lists Figure 20 shows an example with three units —A1, —A2, and —A3.

IEC 61082-1 General Requirements – Amendment 2.pdf

Conductors carrying named signals shall have the signal designations shown at one end of the connecting line on diagrams intended for installation, operation, or maintenance.


CAD lettering of the Latin alphabet, numerals and marks. Electrical drawings and schematics niranjana roy – bsc electrical engineering revision 3 website: If devices are located above each other at several levels, these devices may be shown in the diagram as flipped, turned, or moved in such a way that the devices can be seen by the user of the diagram.

This means that you will have to visit the homepages of your local authorities or websites like www. Switching and peripheral equipment.

The symbol dash — indicates that there is no connection. Preparation of instructions for use — Structuring, content and presentation — Part 1: Low-voltage switchgear and controlgear.

This old standard is being replaced by:. This standard is relevant for documents in all technical areas which are in use during the life cycle of a plant, system or equipment. Metadata elements and information reference model.

Survey of electrical CAD drawing standards

Frre codes shall be in Figure 4 shows a number of examples of how accordance with IEC Revisions British Standards are updated by amendment or revision. The information for the cable end of —W has been supplemented with an item designation for the remote end.

Unit connection diagrams and tables 3. Guidelines for the application of graphical symbols. It is identical with IEC Figure 21 shows an example of a cable table for the same equipment as that shown in Figure Connection points Item —W Figure 9 shows an example of an interconnection diagram using partly single-line representation for the same equipment as depicted in Figure 8. Terminal connection diagrams and tables 5. Structuring of technical information and documentation.

Parts 1 — 6: Other information may be included as free or as Terminals shall be clearly indicated but symbols for appropriate, and shall be included to the extent that terminals need not be shown unless special conditions require their depiction.


Information about the external connections among units need not be included, but references to the appropriate interconnection diagram or table may be provided.

Screened cable —W with frer twisted and screened pairs 2 3 Two cables, interlaced on the diagram; The cable cores of cable —W connected to terminals 11, 12, 14, 16, and 19, those of cable —W connected to terminals 13, 15, 18, 19, and Figure 10 shows an example of an interconnection diagram in which the prefabricated cable —W3 is terminated by means of a connector at each end.

Construction drawings – Designation systems. Connection documents are used when assembling, 2. ISO series — Process measurement control functions and instrumentation – Symbolic representation.


This standard provides rules for the composition of designations and names for the identification of signals and signal connections. Classification and designation of documents 61802 plants, systems and equipment – Part 1: Low-voltage switchgear and controlgear assemblies – Part 1: Some parts of the series are under revision.

Information about the internal connections in the units need not be included, but appropriate references for example reference to unit connection diagram or table or references to internal components by means of their item designationsmay be provided. We share information about your activities on the site with our partners and Google partners: Terminals shall be represented and identified by the terminal designations marked on the device or, as with a dual-in-line package or gree electronic tube, assigned by the manufacturer or by convention.
