Switchboard Upgrades
Ceramic-fuse board swap on a 1970s brick veneer
Homeowner in Strathfield had breakers tripping every time the kettle and toaster ran together. We pulled the old board, installed a modern enclosure with individual RCBOs on every circuit and re-terminated the tails.
Outcome
New compliant board, CCEW issued, zero tripping since.
A terrace in Strathfield South had a warped, weather-damaged meter box on the front facade. We coordinated the Ausgrid outage, relocated the meter, upgraded the board and weatherproofed the new enclosure.
Outcome
Meter moved, board upgraded, heritage frontage preserved.
Owner in Homebush wanted 28 halogens replaced with dimmable LEDs before summer. We spec'd matched trailing-edge dimmers, swapped fittings room-by-room and left clean plaster cut-outs.
Outcome
28 LEDs installed, ~90% lighting energy saved, no flicker.
Kitchen renovation in Homebush West needed even task lighting over the island plus dimmable ambient. We laid out fittings on a 1.4 m² grid, installed pendants over the bench and wired a two-scene dimmer.
Outcome
Bright, even lighting, two dim scenes, no shadow zones.
New Tesla owner in Burwood needed a home charger. We ran a dedicated 32 A RCBO circuit from the switchboard, mounted the Wall Connector in the garage and configured load balancing so the main never trips.
Outcome
7 kW home charging, CCEW issued, ~40 km range per hour.
Homeowner in Croydon with a 6.6 kW rooftop array wanted to charge only from excess solar. We wired a Zappi charger, added the CT clamp on the mains, and configured Eco+ mode so the car sips only spare PV.
Outcome
Free daytime charging from surplus solar, app-managed schedules.
Family in Croydon Park needed a quiet fan in the main bedroom. We removed the existing rose, installed a DC fan on a rated bracket and wired a dedicated wall controller — no pull-cord dangling.
Outcome
DC fan installed, 6-speed wall control, near-silent running.
Alfresco area in Concord needed an outdoor-rated fan over the dining table. We ran a new outlet from a nearby circuit, sealed the ceiling penetration and installed an IP-rated fan with remote.

Outcome
Off-peak restored, hot water back on schedule, meter re-sealed.
Owner in Rhodes replaced a failed 315 L storage tank with a Reclaim heat-pump. We ran the new dedicated circuit, decommissioned the off-peak feed and coordinated the plumber for changeover.
Outcome
Heat-pump wired, CCEW issued, up to 75% less power for hot water.
Living room in Canada Bay was re-arranged and the TV needed to move to the opposite wall. We chased a new outlet into the plaster, ran RG6 quad-shield to the roof antenna and installed a wall-plate.
Outcome
Clean single-outlet install, no visible cabling, full HD/UHF signal.
Home office in Abbotsford needed hard-wired data for two desks. We ran Cat6 from the study back to the modem, terminated on RJ45 wall plates and tested to 1 Gbps.
Outcome
Two 1 Gbps data outlets, tidy runs in the ceiling, no wireless drops.
New tenancy in Drummoyne needed a full electrical fitout inside a two-week window. We handled lighting design, GPO layout, data drops, sub-board, emergency lighting and the exit signs.
Outcome
Fitout complete, CCEW and compliance certificates issued, opened on time.
A home in Ashfield had one shared RCD covering the whole house, tripping every time two appliances ran together. We split the board into individually RCBO-protected circuits and left the mains fed by RCBO.
Adding a ducted air conditioner in Summer Hill overloaded the old fuse-based board. We upgraded to a modern enclosure with extra ways, added a dedicated RCBO circuit for the new unit and re-tested every circuit.
Outcome
New board with spare capacity, dedicated air conditioning circuit, CCEW issued.
After a Haberfield home had its ceiling insulation topped up, the old downlights were no longer insulation-contact rated. We swapped every fitting for IC-rated LEDs safe to cover with insulation.
Outcome
Insulation-safe LEDs throughout, no fire-risk clearance gaps.
A kitchen renovation in Lidcombe wanted shadow-free benchtop lighting. We ran low-voltage LED strip under the overhead cabinets, hid the driver inside the pantry and wired it to the existing downlight switch.
Outcome
Even benchtop lighting, no visible wiring, single switch control.
A new EV owner in Enfield wanted faster charging than single-phase could offer. We confirmed three-phase supply was available, ran a dedicated circuit with the correct RCBO and mounted an 11 kW charger in the carport.
Outcome
11 kW three-phase charging, CCEW issued, full charge overnight.
A Belfield household bought a second EV and needed a matching charger beside the first. We checked available switchboard capacity, added load management between both chargers and ran the new circuit.
Outcome
Two chargers sharing capacity safely, no board upgrade needed.
A bedroom in Campsie only had a bare batten holder and no fan. We installed a fan-light combo on a proper ceiling brace, wired a separate fan and light control and patched the ceiling rose.
Outcome
Fan and light on separate switches, ceiling properly braced.
High-void fan with extension rod for a raked ceiling
A living room in Kingsgrove had a raked ceiling too high for a standard fan mount. We fitted an extended down-rod, confirmed blade clearance and wired a wall control within easy reach.
Outcome
Fan mounted safely at the right height, smooth wall control.
Ahead of a sale in Earlwood, the vendor needed alarms brought up to current standard. We replaced ageing 9V units with interconnected 10-year lithium alarms in every required location and issued a compliance statement.
Outcome
Fully compliant alarms ahead of settlement, statement issued for the contract.
A rental property in Canterbury had alarms that weren't interconnected, falling short of NSW rental rules. We hard-wired and interconnected alarms across every level so one trigger sounds them all.
A bathroom addition in Hurlstone Park needed power for a new continuous-flow electric hot water unit. We ran a dedicated high-amp circuit from the switchboard and installed the correct isolator at the unit.
Outcome
Dedicated circuit installed, continuous hot water, isolator compliant.
Lukewarm water in a Dulwich Hill home traced back to a failed thermostat in the electric storage tank. We isolated the circuit, replaced the thermostat and element cutout, and confirmed safe operating temperature.
Outcome
Hot water restored, safe thermostat cut-out confirmed.
A home office in Lewisham kept losing power for no obvious reason. We traced it to a loose neutral connection in a downstream junction box, re-terminated the joint and tested the circuit under load.
Lights flickering across two rooms in Petersham pointed to a wiring fault. We traced a shared neutral between circuits back to the switchboard, separated the wiring and confirmed steady voltage on both.
A safety switch in Newtown kept tripping whenever it rained. We isolated the fault to water ingress in an outdoor power point, replaced it with a weatherproof IP-rated unit and resealed the cable entry.
Outcome
Weatherproof GPO installed, RCD no longer trips in wet weather.
An audible buzzing from the switchboard in Leichhardt was reported before it got worse. We found a breaker with a degraded internal contact, replaced it and thermal-imaged the board to rule out other hot spots.

Outcome
Independent metered supply approved and connected.
High winds in Balmain East pulled the point of attachment away from the roofline. We repaired the mounting, restrung the service line to the correct tension and cleared it for reconnection.
Outcome
Attachment point repaired, service line reconnected safely.

Outcome
Full perimeter coverage, 30-day recording, remote alerts enabled.
A Chiswick homeowner wanted their existing cameras and a new doorbell camera on one system. We integrated the doorbell into the existing NVR, ran a dedicated PoE line to the front door and tested the combined recording.
Outcome
Doorbell and existing cameras unified on one recording system.
A new split system in Liberty Grove needed its own protected circuit rather than sharing an existing GPO. We ran a dedicated RCBO circuit from the switchboard to an isolator beside the outdoor unit.
Outcome
