Could it be smoke from cooking or another source?

A burning electrical smell is distinct from organic combustion. If you can localise the smell to the switchboard area, it is electrical until proven otherwise. When in doubt, call us.

We had a sparking outlet last week and now the switchboard smells. Are they connected?

Quite possibly. A sparking outlet that hasn't been repaired can stress the upstream breaker over time. We see this pattern frequently. Both faults need addressing together.

The main switch trips when I smell burning. What now?

The main switch is doing its job — but the fault is still inside the board. Don't reset. Leave it OFF. Call us.

How quickly can you respond?

Switchboard burning smells are our highest priority dispatch — typical response 30–60 minutes across metropolitan Sydney 24/7. Call 0433 462 902 for an immediate ETA.

Will my house catch fire if I ignore a burning smell from the switchboard?

Yes — it can, and faster than most people expect. An energised terminal charring through its insulation can ignite the surrounding plastic and timber inside the meter box within minutes, and switchboard fires typically spread into the wall cavity before a smoke alarm triggers. Treat any burning smell at the board as a fire-risk emergency, not a wait-and-see situation.

Is it safe to stay in the house while I wait for the electrician to arrive?

If the smell is faint and there is no visible smoke, turn off the main switch if it is safe to reach, keep everyone away from the meter box, and wait in a part of the house well away from the board. If the smell is strong, intensifying, or smoke is visible, leave the property immediately and call 000 before calling an electrician.

How much does it cost to fix a burning switchboard in Sydney?

The cost varies depending on whether the fault is a loose terminal, a failed neutral link, damaged wiring, or a full switchboard replacement. Call Sydney Electrical Service on 0433 462 902 for a fixed-price quote — emergency call-out pricing is confirmed upfront with no hidden charges.

Who should I call first if I'm renting and my switchboard smells like burning?

Call an emergency electrician immediately — your safety takes priority over any landlord notification. Under NSW tenancy law your landlord is responsible for urgent electrical repairs, but the right order is: make the emergency call first, then notify your property manager or real estate agent straight after.

Do I really need a licensed electrician, or can I just re-tighten the terminals myself?

You must use a licensed electrician — in NSW it is illegal for anyone other than a licensed electrical contractor to carry out electrical work, including tightening terminals inside a switchboard. Beyond the legal risk, reaching into a board with the supply still live carries a lethal electrocution risk even for experienced tradespeople.

Castle Hill and Baulkham Hills include established 1980s–90s brick veneer suburbs alongside newer 2000s estates — meaning Hills District electricians need to handle both legacy aluminium-busbar boards and modern RCBO-protected installations within the same suburb.

In the Hills District, large modern homes, acreage and granny flats lean hard on three-phase boards feeding big air-con, pumps and chargers. A burning smell means one phase or connection is overheating under that demand, so kill the main switch and call us urgently rather than risking a melted board or an electrical fire.

⚠ 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 Cherrybrook

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.

Electrical work in Cherrybrook

Cherrybrook is a planned, family-oriented suburb built largely through the 1980s and 1990s, with consistent double-brick homes, plenty of two-storey designs and a good amount of underground power on the newer estates. The era means most boards are getting on in years — fixed-wired without RCDs on every circuit, often crowded after years of added pool, air-conditioning and kitchen-renovation loads. Sitting on the Ausgrid–Endeavour boundary, supply in parts of Cherrybrook is handled by your local network distributor, so we confirm the network before any connection work.

The big-ticket jobs here are switchboard upgrades with full RCD and surge protection, three-phase upgrades for larger two-storey homes running multiple aircon heads and EV chargers, and dedicated circuits for renovated kitchens and outdoor areas. On the underground-supplied estates we carry out Level 2 consumer mains and metering work, while the older overhead-fed streets often need point-of-attachment and service-line attention. We sort the network connection and the board in one coordinated visit.

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.
