////// Mission
We design, install, test and maintain the electrical systems behind towers, plants, hospitals and data centres. One accountable team from the 11 kV intake to the last socket outlet.

Remote monitoring
We see the fault
before you do.
Every maintenance contract includes metering on your main LV panels. Our control room watches voltage, frequency, power factor and harmonics around the clock and dispatches a crew when a reading drifts.

What we power
From intake
to outlet.
Most outages trace back to a gap between trades. We hold the full chain in one contract: design, supply, installation, testing and the maintenance that follows.

Five stages.
One team.
The same project engineer stays with you from the first site survey to handover, and the same team answers the phone when you need maintenance.
01
Survey
Site walk, load schedule review and existing-condition report within 72 hours.
02
Design
Single-line diagrams, cable sizing, discrimination studies and authority drawings.
03
Install
Certified crews, permit-to-work control and daily progress reports.
04
Commission
Witnessed testing, protection settings and full as-built documentation.
05
Maintain
Planned maintenance, remote monitoring and a 24/7 emergency line.

About Nexaris
Twenty years of
keeping the lights on.
We started in 2006 as a twelve-person fit-out crew. Today Nexaris is a 480-strong, MV-licensed contractor with its own panel factory, testing division and a 24/7 remote monitoring centre.
Why clients
stay with us.
Electrical work is invisible when it is done well. Our clients notice us twice: when a project is handed over on time with complete documentation, and when something fails at 3 a.m. and we are already on the way.
Seventy-eight percent of our work comes from repeat clients, and most of our 340 active maintenance contracts started as a single installation project.
Safety
Zero-harm sites
Permit-to-work on every job and 3.4 million hours without a lost-time injury.
Ownership
One point of contact
A named project engineer who stays from survey to handover.
Evidence
Test, record, hand over
Every circuit tested, every result logged, every drawing as-built.

Solutions by industry
Built for the load
you actually run.
A hospital theatre, a cold store and a residential tower have very different failure costs. We design around yours.
Selected projects
Energised,
tested, handed over.
A sample of recent work. Every project shown was delivered with full as-built drawings and a test pack.
Client view
“They energised a 4 MVA substation over a weekend shutdown and we opened on Monday as planned.”Facilities Director, 42-storey mixed-use tower

Before you call
Common questions.
How quickly can you send a quote?
For most fit-out and maintenance work we quote within three working days of the site survey. Large MV projects with design scope take one to two weeks.
Do you handle authority approvals?
Yes. We prepare and submit drawings, attend inspections and coordinate the utility connection and energisation.
What does a maintenance contract include?
Quarterly inspections, annual thermographic survey, breaker servicing, remote monitoring where fitted and a guaranteed 4-hour on-site response.
Can you work around live operations?
Yes. We plan shutdowns for nights and weekends and use temporary generators so hospitals, hotels and data halls stay running.
