Mosman, Cremorne, and Neutral Bay harbour-side properties combine high property values with the typical Lower North Shore electrical patterns: large multi-circuit boards, extensive outdoor entertaining circuits, pool/spa/jacuzzi equipment, and the salt-air corrosion from harbour exposure.

Across the North Shore, big leafy homes and Chatswood strata towers are stacking EV chargers, data cabinets and home automation onto boards never built for that load. A burning smell means something is running hot under the demand, so isolate the main switch and call us before a melted neutral takes out the lot.

⚠ Stop — Call Immediately if You Notice Any of These:
  • Live arc fault at 230 V, capable of igniting surrounding combustibles in seconds
  • Smoke inhalation as plastic insulation pyrolises
  • Electrocution risk if you attempt to investigate inside the board
  • Wall and ceiling cavity fire propagating before smoke alarms activate
  • Visible smoke from the switchboard
  • Smoke seeping from a wall, ceiling, or floor near the board
  • Audible crackling, popping, or buzzing from the board
  • Visible flame or glow inside the board
  • Heat radiating from the wall around the board
  • Soot streaks above or beside the switchboard
  • A burning smell rapidly intensifying

About Burning Smell from Switchboard – Urgent Action Required

A burning smell from a switchboard is caused by a loose terminal overheating, an overloaded circuit, a failing neutral link, or degraded wire insulation inside the meter box. It becomes dangerous the moment charring starts — an energised connection can ignite surrounding plastics within minutes, so book an emergency response or call Sydney Electrical Service on 0433 462 902 now. If you can smell burning at the switchboard right now, switch off the main switch if it is safe to reach and keep all occupants away from the area. If smoke is visible, call 000 first.

What to Do Right Now in Mosman

  1. Get all occupants away from the board including pets.
  2. If smoke is visible, call 000 immediately. Do not attempt to investigate.
  3. If no smoke is visible, switch the main switch to OFF — only if you can reach it without putting your hand inside the board cover.
  4. Do not open the switchboard cover. Never under any circumstances.
  5. Do not use water on the switchboard even if smoke is present — it will spread the fault.
  6. If you have a CO2 fire extinguisher and smoke is present, only use it on visible flame after isolation, never inside an energised board.
  7. Open windows and ventilate the area if smoke is present.
  8. Photograph the switchboard from a safe distance for diagnostic dispatch.
  9. Call 0433 462 902 immediately — emergency dispatch is priority over any other job.

Electrical work in Mosman

Mosman is one of Sydney's older harbourside suburbs, and its housing reflects that. You'll find grand Federation and late-Victorian homes, plenty of interwar and Art Deco walk-up flats around the village and Military Road, and substantial harbourfront residences down toward Balmoral and the foreshore. A lot of these properties sit within heritage conservation areas, so meter boxes and switchboards often need to stay discreet and the original fabric left intact. In practice that means we regularly come across ageing rubber or VIR wiring well past its life, two-wire setups with no earth, and undersized fuse boards that need rewiring and proper safety switches to meet current standards.

Being right on the harbour, salt air takes its toll on outdoor switchboards, metering enclosures and consumer mains, so corrosion checks matter here. As an Ausgrid-accredited Level 2 ASP, we handle the network-side work too: overhead and underground service connections, point-of-attachment and consumer mains upgrades, metering, and three-phase supply for larger renovated homes. We also sort strata switchboards across Mosman's many flats and unit blocks.

Common Questions

A burning, fishy, plastic, or ammonia-like odour distinct from cooking smells. Many people describe it as "burnt insulation" or "hot wire" — it has a sharp, chemical character that doesn't disperse quickly.
Yes — if you can reach it from outside the board cover and you don't see smoke. Removing the load stops further heating. If you see smoke or fire, call 000 immediately and stay back.
No. Never. The internal busbars are live unless physically disconnected at the service fuse, and an arc flash from a 230 V or three-phase supply can cause severe burns and electrocution.
No — it can be more dangerous because the cause is still building. An intermittent smell often means a connection only heats up under load. Once the load increases sufficiently, the connection ignites without further warning.

Why Mosman Residents Choose Us

North Shore strata buildings — particularly the 1980s–90s mid-rise apartments through North Sydney, Crows Nest, and Chatswood — make up a significant share of our local work. We provide AGM-ready quote documentation and body-corporate-friendly scheduling as standard.
