What electrical drafting actually involves

Electrical drafting documents how a system is wired, powered and protected — from single-line diagrams that show the overall power distribution down to the panel layouts, schematics and cable schedules an electrician or switchboard builder works from. Accuracy matters because these drawings carry compliance obligations: circuits, protection devices and equipment ratings have to align with the wiring rules and switchgear standards before anything is energised.

What we deliver

  • Single-line & schematic diagrams — power distribution, control circuits and protection coordination.
  • Switchboard & panel layouts — general arrangements and internal layouts to AS 61439.
  • Wiring & termination diagrams — point-to-point and loop drawings for installation and commissioning.
  • Cable schedules & equipment lists — sizing, routing and tray layouts.
  • Lighting & power layouts — for commercial, industrial and infrastructure projects.

Common questions

Do your electrical drawings meet Australian wiring rules? Yes. We draft to AS/NZS 3000 (the Wiring Rules) and AS 61439 for switchgear assemblies, with the relevant building-services standards applied for coordinated MEP work.

Can you work from a hand sketch or a marked-up PDF? Yes — a designer’s sketch, a redline on an existing drawing, or a previous DWG are all enough to start. We turn it into a clean, compliant drawing set.

How is an electrical job priced? Fixed-price per project based on the number and complexity of diagrams and layouts. The cost is agreed before work begins; we do not bill hourly.
