        Selecting and Dimensioning of Cables and Wires

        by Herbert Schmolke

        This compact paperback guide assists you in selecting cables and wires in accordance with technical specifications and standards, and in calculating their requirements. The book focuses on the selection of cables and wires: for protection against overcurrent in accordance with DIN VDE 0100-430, for special loads, with special properties, and with regard to special features in the planning and installation of cable and wire systems. The 9th edition of this classic has been updated throughout. Among other things, the revision takes into account the current DIN VDE 0298-4:2023-06 “Use of cables and insulated conductors for power installations” and DIN VDE 0100-520:2023-06 “Installation of low-voltage systems: Selection and installation of electrical equipment - Cable and conductor systems.” Six formula-based tables are also available for download online: for current, cable, and line calculation, for checking the line cross-section, and for determining the rated current of overcurrent protection devices.They enable most of the calculations covered to be performed in a very time-saving manner.

        KNX/EIB Engineering Tool Software

        Safe Installation and Changeover from ETS5 to ETS6

        by Michael Körmer, Willi Meyer

        Smart home solutions are in vogue, but require precise knowledge of the underlying hardware and software. Those who do not deal with ETS programming on a daily basis sometimes find it difficult. Instead of relying on memory and colleagues' knowledge for setup, this book helps as a step-by-step guide: the overall process of programming and commissioning KNX/EIB projects based on the current Engineering Tool Software (ETS) is covered. This enables you to follow all the necessary steps before, during and after processing with ETS5 and ETS6 "in one piece". The book takes into account the current state of the software based on ETS5 as well as ETS6. From the determination of requirements to the documentation, the necessary knowledge is conveyed. All actions with the discussed software tools are illustrated by screenshot, which ensures a good comprehensibility. For practical understanding, the complete project of a single-family house is also presented step-by-step and richly illustrated. This book will help you especially with the following questions: What are the basics of KNX hardware and software? What basic knowledge do I need specifically for ETS5 and ETS 6? What are the differences and similarities between the two KNX tools? How do I lead an extensive KNX project to success? (Practical example)
