Tree-heavy suburbs — Wahroonga, Killara, Pymble, Hunters Hill, Lane Cove — see the highest rate of overhead consumer mains damage in metro Sydney. East-coast lows and storm-driven branches account for hundreds of point-of-attachment and service-mains callouts every storm season.

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 Hornsby

  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 Hornsby

Hornsby's housing is a real mixed bag, and the wiring tells the story. You've got pockets of Federation-era and older character homes alongside the streets of 1960s-to-1990s brick-veneer houses that dominate the area, sitting on big leafy blocks backing onto bushland. The older stock is where we see tired switchboards with ceramic rebewireable fuses, aged rubber or early PVC cabling, and no RCD safety switches, all of which are worth bringing up to current standards. On the bushland fringe, where so much of Hornsby sits, neat cabling, sound switchboards and properly rated circuits matter even more, especially for anyone running pumps, sheds or detached studios down the back.

Closer to the station and through Waitara, the newer R3/R4 strata blocks bring their own work: common-property switchboards, sub-metering and three-phase supply for lifts and shared services. Bigger renovated and knock-down-rebuild homes often need a three-phase upgrade and a board rebuild to handle ducted air-con, induction cooktops and EV chargers. As a Level 2 ASP working on the Ausgrid network, we handle the connection side too: consumer mains, point-of-attachment and metering work that a standard electrician can't legally touch.

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.
