Power infrastructure, engineered to the standard.
Nexus Grid Electrical designs, installs and certifies electrical infrastructure across residential, commercial and industrial assets. We engineer every circuit to AS/NZS 3000, model maximum demand before we cut a cable, and hand over documentation a verifier can sign.

We treat electrical work as infrastructure, and compliance as the spec.
Nexus Grid designs, installs and certifies electrical systems the way a verifier reads them: sized by calculation, protected by coordination, and documented for life.
Whole-of-asset capability
From a single power point to three-phase distribution and motor control — one licensed, accountable team across the stack.
Engineered, not estimated
Every job begins with a maximum-demand calculation and a load schedule. We size to the standard, not to a rule of thumb.
Compliance built in
AS/NZS 3000, 3008, 3017 and 3760 are designed in from the first drawing — and proven on handover with test results.
24/7 fault response
A monitored emergency desk with a median 18-minute metro ETA isolates hazards and restores supply, safely.
Every circuit starts as a wireframe — then resolves into certified reality.
We model the load schedule, circuit topology and protection grading in design long before a conductor is pulled. The result is an installation with calculated cable sizes, a coordinated discrimination plan and an earthing system that passes verification the first time.
Maximum-demand calculated
Load schedules to AS/NZS 3000 Section 2 size mains, sub-mains and switchgear correctly — no nuisance tripping, no overload.
Cable & voltage-drop sized
Conductors selected to AS/NZS 3008 with voltage drop held under the 5% Wiring-Rules limit across the run.
Tested & certified
Insulation resistance, earth continuity, polarity and RCD trip times verified to AS/NZS 3017 before energising.
Twenty ways we power, protect and connect your property.
From a domestic rewire to industrial motor control, structured data cabling and emergency response — engineered with the same analytical rigour.

Open specAssess. Design. Install. Certify.
A disciplined pipeline from site inspection to a tested, documented and compliant installation — accountable at every gate.
Assess
Site inspection, maximum-demand calculation and a load schedule establish a defensible design before a cable is cut.
Design
Circuit topology, cable sizing to AS/NZS 3008 and protection coordination produce a documented, verifiable plan.
Install
Licensed installation with correct segregation, IP ratings and earthing — built to the Wiring Rules, not to a budget.
Certify
Full testing to AS/NZS 3017, a Certificate of Electrical Safety and a documented as-installed record on handover.
