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.

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 Pennant Hills

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 Pennant Hills

Tucked into Hornsby Shire's bushland edge, Pennant Hills is a settled family suburb where generous gardens and big homes are the norm. Much of the stock dates from the post-war and 1970s building boom, with plenty of original wiring and modest switchboards still in service decades later. As these homes are extended or modernised, the existing electrical capacity quickly falls short of what a contemporary household with multiple split systems, a workshop and high-draw appliances actually demands.

We spend a lot of time here upgrading switchboards with proper RCDs and circuit breakers, rewiring older runs of perished cabling, and stepping homes up to three-phase to handle the load. On the network side, as a Level 2 ASP accredited with Ausgrid, we look after consumer mains, overhead and underground service connections and storm-damaged point-of-attachment repairs, common given the heavy tree canopy. Heritage-style and rebuilt homes alike benefit from a properly sized, safe supply.

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.
