About

Electrical and solar work, from the drawing to the last torque

As an electrical engineer, I work on medium and low voltage installations as well as ground-mounted and rooftop photovoltaic plants. My scope covers study, sizing, installation, commissioning and maintenance.

What makes an installation last is neither the equipment alone nor the speed of execution: it is the consistency between the drawing, the tagging, the protection and the documentation handed over to the client. That consistency is what I aim for on every job.

  • New projects and existing installations to be diagnosed
  • Compliance upgrades, extensions and system evolution
  • Strict tagging and a technical file handed over at completion

Method

How I run a project

Every job follows the same sequence, from the first site visit to the handover of the file. You always know where the work stands and what is left to do.

  1. 01

    Site survey & study

    Site visit, survey of existing systems, load schedules and single-line diagrams.

  2. 02

    Sizing & design

    Selection of protection, cables and switchgear, calculations and the execution file.

  3. 03

    Installation & testing

    Assembly, tagged wiring, connections, verification and controlled energising.

  4. 04

    File & follow-up

    As-built drawings, tagging, operating instructions and a maintenance schedule.

Deliverables

What you receive at the end of the job

Ask for a sample file

Technical file

Single-line and as-built drawings

Drawings that reflect the installation as it was actually built, not as it was originally planned.

Tagging

Circuit labelling and identification

Every outgoing circuit, wire and protective device identifiable without opening the panel.

Operation

Operating instructions & maintenance plan

Isolation procedures, inspection intervals and the points the operator should watch.
