Hills District homes face a combination of modern appliance density, EV/solar integration complexity, and three-phase capacity questions that drive the typical electrical work we deliver across Castle Hill, Baulkham Hills, Kellyville, Bella Vista, Cherrybrook, and surrounding suburbs.

⚠ 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 Castle Hill

Get all occupants away from the board including pets.
If smoke is visible, call 000 immediately. Do not attempt to investigate.
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.
Do not open the switchboard cover. Never under any circumstances.
Do not use water on the switchboard even if smoke is present — it will spread the fault.
If you have a CO2 fire extinguisher and smoke is present, only use it on visible flame after isolation, never inside an energised board.
Open windows and ventilate the area if smoke is present.
Photograph the switchboard from a safe distance for diagnostic dispatch.
Call 0433 462 902 immediately — emergency dispatch is priority over any other job.

Common Questions

What does an overheating switchboard smell like?

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.

Should I switch off the main switch if I smell burning?

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.

Can I just open the board to look inside?

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.

The smell is mild and intermittent. Is that less dangerous?

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.
