How to

How to use a single‑line diagram template.

  1. 01Start at the service head

    Name the incoming supply (voltage, main fuse/isolator rating) — the AI places the main switch and meter.

  2. 02Add main protection

    Describe the main isolator and RCD/RCCB; the AI uses the correct IEC symbols and ratings.

  3. 03Branch the final circuits

    List each circuit (lighting, sockets, kitchen, EV charger) with its MCB/RCBO rating and cable size.

  4. 04Export for certification

    Export PNG/SVG for the electrical installation certificate or inspection submission.

FAQ

Questions about single‑line diagram templates

What is a consumer unit single-line diagram?

A diagram of a domestic distribution board showing the main switch, RCDs, and the MCBs/RCBOs protecting each final circuit, with cable sizes and ratings.

What is the difference between an MCB, RCD, and RCBO?

An MCB protects against overcurrent (overload/short circuit). An RCD protects against earth leakage (shock). An RCBO combines both in one device for a single circuit.

Which standard applies to residential wiring diagrams?

IEC 60364 is the international base standard. Regional variants include BS 7671 (UK), NEC (US), and REBT (Spain). ChatDiagram uses IEC symbols and you specify the regional ratings.
