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.
