About N1
01 / 03

We are a senior electrical engineering team powering data centres and large construction.

We design, build and commission the switchboards, generators and distribution that critical facilities depend on.

Every circuit is tested, documented and handed over, ready to perform from first energisation.

What we do01 / 04

Four disciplines. One team accountable from first drawing to final energisation.

We specialise in the electrical work where the cost of failure is highest. Our engineers stay with a project from concept to close-out, so the people who design your system are the people who commission it.

Approach01 / 04

Design, build, commission, hand over. One continuous line of responsibility.

  1. CAD workstation displaying a dense electrical schematic

    Design

    01

    Load studies, single-line diagrams and coordinated documentation that anticipate how the site will be built.

  2. Switchboard under construction on a workshop bench with a part-terminated loom

    Build

    02

    Switchboards, reticulation and containment installed by crews who understand the design intent.

  3. Load bank connected to a distribution board with heavy test cables

    Commission

    03

    Staged testing through to integrated systems, with load banks, witness points and recorded results.

  4. Bound binder and USB drive on a steel bench beside a framed certificate

    Hand over

    04

    As-builts, test records, O&M manuals and certification delivered complete, on the day.
