Plant-room shaped. Crew-friendly.

The electrical scope around HVAC plant is its own discipline — sized to nameplate, isolated to code, and wired so the mech crew can commission without a queue at the board.

01

Power to plant, day one.

Cable size and circuit count built around the unit nameplate — RLA, MCA, starting current. Sub-board space scoped before the install hits site, not after.

02

Isolation, code-compliant.

AS/NZS 3000 isolation at every outdoor unit, IP-rated for rooftop and external mounts, lockable where the standard asks for it. Documented per circuit.

03

Fire and BMS interfaces.

Smoke-control mode wiring, EWIS fan trip, BMS DI / DO termination — wired neatly, labelled, and commissioned alongside the mech crew.

04

After-hours, rooftop-ready.

Out-of-trading scheduling for occupied sites. We coordinate roof access, hoists, EWPs and base-building rules so commissioning day isn’t the day we discover the lift’s booked out.
