Electrical Documentation, Schematics and BOM Packages
Before installation starts, your team needs a single-line diagram, a device list and cable schedules that actually match the job — not a sketch on the back of an envelope. We turn your project brief into a coordinated documentation package your installer or procurement team can work from directly.
How the documentation package comes together
Requirements
You describe the building, rooms, existing situation and what you want to achieve — new panel, extension, smart-home automation, or a mix.
Concept draft
We prepare an initial layout and schematic for discussion, so you can react to a real drawing instead of a blank page.
Revision rounds
You comment, we refine — the single-line diagram, panel layout and schedules converge on what will actually get built. The number of rounds and timing depend on project scope.
Final package
You receive the finished documentation set — diagrams, schedules and BOM — ready to hand to an installer or procurement.
Why a complete package matters
Documentation ahead of installation
A coordinated design package means the installer arrives with a plan, not a guess — and procurement knows exactly what to order before site work starts.
Clean procurement
A device/BOM list means your buyer orders the right components once, instead of estimating quantities on site.
Faster on-site work
An installer working from a schedule doesn't stop to work out routing or numbering — it's already decided on paper.
Fewer surprises during installation
Conflicts between circuits, spare capacity and layout get caught on the drawing board, not halfway through a wall.
Coordination across trades
Power, low-voltage cabling (KNX, UTP) and smart-home devices are planned together, so routes and boxes don't collide.
A paper trail for handover and inspection
Clear documentation supports inspection and gives client, installer and electrician the same reference.
What's inside the package
The exact set of documents depends on project scope — not every order includes all of them.
- {'t': 'Single-line / schematic diagram', 'd': 'The concept drawing showing the electrical distribution structure — the reference your electrician builds from.'}
- {'t': 'Panel layout and schedule', 'd': 'Device arrangement inside the enclosure, with spare space accounted for future additions.'}
- {'t': 'Cable and circuit schedule', 'd': 'Every circuit and cable run listed with its purpose, delivered as an editable table so it can be updated as the project moves.'}
- {'t': 'Device / BOM list', 'd': 'The components the design calls for, structured so procurement can quote and order without re-deriving it from the drawing.'}
- {'t': 'Formats: PDF/DWG concept drawings, editable schedules', 'd': 'Diagrams are typically delivered as PDF or DWG; schedules and BOM as editable spreadsheet-style files your team can keep updating.'}
Frequently asked questions
Do we get every document listed here?
Not necessarily — the set depends on your project's scope and complexity. Larger or automation-heavy projects typically need more of the package than a simple panel swap.
What file formats do we receive?
Concept diagrams are usually PDF or DWG; cable, circuit and BOM schedules are delivered as editable spreadsheet-style tables so your team can keep using them after handover.
How is this different from as-built panel documentation?
This package covers the design stage — drawings and schedules produced before installation begins. As-built documentation is produced after the work is finished and reflects what was actually installed; see our panel documentation and cable management pages for that stage.
How much does it cost and how long does it take?
Both depend entirely on project scope and complexity — there's no fixed price or turnaround we can quote in general. Request a quote and we'll size it to your project.
Who does the actual installation and sign-off?
We deliver design documentation, not installation. The final connection, commissioning and sign-off is always carried out by a certified electrician under applicable national wiring rules.
