Full title and description

DIN 18015-1:2020-05 — Electrical installations in residential buildings - Part 1: Planning principles (German: Elektrische Anlagen in Wohngebäuden - Teil 1: Planungsgrundlagen). This part gives the fundamental requirements and guidance for planning electrical installations in residential buildings (single-family, semi-detached, terraced and multi-family dwellings), including buildings with partial commercial use; it updates references to current rules and includes guidance on documentation and integration of energy storage.

Abstract

Part 1 of the DIN 18015 series sets out planning principles for electrical power supply and distribution in residential buildings. The 2020 revision updates normative references, clarifies requirements for earthing and protective measures, adds guidance on surge protection and the integration of energy storage, and expands recommendations for documentation with examples in a new annex. It is intended to be used together with relevant VDE and grid-connection application rules where applicable.

Scope

The standard applies to the planning of electrical installations in residential buildings and can be applied by analogy to buildings with comparable requirements. It covers the supply connection, main lines, internal distribution, earthing and equipotential bonding, protective measures (including recommendations for overvoltage/surge protection), and documentation of the installed system. The standard does not specify transmission technology for communication applications; it is intended to be used alongside applicable VDE rules and grid-connection application rules.

Key topics and requirements

• Planning principles for power supply and distribution in dwellings (layout, load considerations, feeder/main distribution).
• Requirements for earthing, main earthing busbars and protective equipotential bonding (references to DIN 18014 and network operator requirements where relevant).
• Guidance and requirements for overvoltage / surge protection, including considerations for the mains/utility connection and selective protection measures.
• Integration considerations for energy storage systems and other building energy technologies (planning and documentation implications).
• Expanded documentation requirements for the executed installation with examples provided in a new annex (Annex C in the 2020 edition).
• Cross-references to applicable VDE rules and network-connection application rules (e.g., VDE‑AR‑N 4100) for grid interaction and coordination of protective devices.

Key technical changes and emphases in the 2020 edition are described in the DIN information and industry summaries.

Typical use and users

Primary users are electrical planners, consulting engineers, architects, installation contractors and building owners involved in the design, specification and verification of electrical installations in residential buildings. Authorities, building inspectors and network operators may also use the standard for reference when assessing compliance of planning documentation and protective measures.

Related standards

The document is part of the DIN 18015 series (other parts address minimum equipment, wiring and component placement, and special topics such as airtightness). It is intended to be used together with national electrical installation rules and VDE standards; important related references include DIN 18014 (earthing), VDE application rules and grid-connection rules such as VDE‑AR‑N 4100 for requirements in the pre-meter/main-supply area.

FAQ

Q: What is this standard?

A: DIN 18015-1:2020-05 is the DIN standard that provides planning principles for electrical installations in residential buildings (Part 1 of the DIN 18015 series).

Q: What does it cover?

A: It covers planning-level requirements for supply, distribution, earthing and bonding, protective measures (including surge protection), and documentation for electrical installations in dwellings; it also updates references to current grid and VDE application rules and adds guidance on integrating energy storage.

Q: Who typically uses it?

A: Electrical planners, consulting engineers, installers, architects, building owners and authorities involved in residential building electrical design and acceptance.

Q: Is it current or superseded?

A: The 2020-05 edition is the current edition and supersedes DIN 18015-1:2013-09. As of the latest available catalogue information the 2020 edition remains the active version. Users should always confirm status with the DIN catalogue or national standards body for the most recent updates.

Q: Is it part of a series?

A: Yes — it is Part 1 of the DIN 18015 series on electrical installations in residential buildings; other parts (for example Part 2 on minimum equipment and Part 3 on wiring and equipment disposition) cover complementary topics.
