If your power has gone out twice in a few weeks, and your switchboard switch trips immediately every time you try to reset it, that is not something to ignore. When it happens during or after heavy rain, water ingress into an outdoor fitting, light fitting, wall cavity, underground conduit, or damaged cable becomes a real possibility.
A breaker or safety switch that trips immediately after being reset usually means the circuit is detecting a fault. It should not be repeatedly reset. Turn off the affected circuit if it is safe to do so, avoid touching wet electrical fittings, and arrange a licensed electrician to inspect the installation.
For Five Dock homeowners, Russo Electrical provides residential electrical fault-finding services, including fault finding, switchboard upgrades, repairs, and urgent safety work. If your power is repeatedly failing during rain, call 0485 009 500 for the earliest available inspection.
Why This Pattern Is Concerning
One outage can sometimes be caused by a grid fault, a storm-related supply interruption, or a one-off overloaded circuit. But two complete outages in a short period—especially during heavy rain—suggests a recurring fault.
The fact that the switch at the switchboard kept tripping immediately is particularly important. A circuit breaker or safety switch is designed to disconnect power when it detects a dangerous condition. If it trips again straight away, the fault is still present.
A breaker that trips and will not reset should be assessed by an electrician. Repeatedly resetting it can mask the underlying problem and may allow overheating, arcing, or water-related deterioration to continue.
Could Rainwater Be Causing It?
Yes. Rainwater can enter electrical systems through several paths, particularly in older homes, homes with roof leaks, damaged outdoor fittings, poorly sealed wall penetrations, or drainage issues around the property.
Possible water-related causes include:
An emergency electrician should be contacted when water gets into electrics. Do not touch wet electrical equipment, and switch off power at the main switch if it is safe to do so.
Why the Switch Trips Only After Some Lights Are Turned Off
If power returned after you turned off some lights, the fault may be on one of those lighting circuits—or on a fitting connected to one of them.
For example, water may have entered a ceiling-mounted light, external wall light, sensor light, or bathroom exhaust fan. When that circuit is energised, moisture or a damaged component creates a fault path, causing the safety switch or breaker to trip. Turning off the affected light may temporarily stop the fault from completing its circuit.
That can make the problem seem resolved, but it is not. The underlying moisture, damaged fitting, or compromised cable may still be present—and it may worsen with the next period of rain.
Common Causes of Repeated Tripping
A tripping switch is a protective response, not the root cause. Common causes include:
Frequent breaker trips, flickering lights, unusual odours, warm outlets, and buzzing sounds may indicate an electrical problem. Repeated breaker trips can also indicate an overloaded circuit, short circuit, or a fault in the distribution board.
Warning Signs That Make It Urgent
Contact an emergency electrician promptly if you notice any of the following:
Burning smells, sparks, hot sockets or switches, and water ingress are recognised emergency electrical warning signs. Hot switch plates and outlet covers, buzzing sounds, overheated-plastic odours, and frequently resetting breakers are also listed by the CPSC as electrical safety warnings.
What to Do Right Now
If the power is currently working but the problem has happened more than once:
Do not keep resetting the tripping switch. Reset it only once if it is safe, and stop if it trips again.
Turn off the lighting circuits or circuits that appeared to trigger the fault, especially if power returned after you switched them off.
Avoid using outdoor powerpoints, garden lights, and wet-area fittings until they have been inspected.
Keep people and pets away from damp walls, ceilings, light fittings, and outdoor electrical equipment.
Do not touch wet switches, powerpoints, or appliances.
Check for visible water entry, such as ceiling stains, damp plaster, dripping fittings, or water near outdoor outlets—but do not open fittings or remove cover plates.
Call a licensed electrician and explain that the outage has happened twice, occurs during rain, and that the switchboard switch trips immediately when reset.
Turning off the breaker for the affected circuit and calling a licensed electrical contractor is recommended for overheating outlets, burning smells, sparks, and repeated breaker trips.
What an Electrician Will Investigate
A proper diagnostic visit is more than resetting the switchboard. The electrician will aim to identify the circuit causing the fault and the reason behind it.
They may check:
They may also use insulation-resistance testing, circuit isolation, and systematic fault-finding methods to narrow down the affected section. This is important because a symptom at a light fitting can sometimes originate from damaged cable, a junction box, or a connection elsewhere on the circuit.
Is This an Emergency?
It can be. Even if power is currently restored, the combination of repeat outages, immediate tripping, and heavy rain means the fault may still be active or likely to return.
Treat it as urgent if:
Emergency electricians are commonly needed for burning smells, scorch marks, buzzing or crackling, hot sockets or switches, water ingress, and a total loss of power affecting only the home.
If the power is currently stable and there are no burning smells, sparks, heat, or water near fittings, it may be possible to arrange the earliest available diagnostic appointment rather than an after-hours emergency call-out. However, do not use the affected lighting circuits or outdoor fittings until they have been checked.
Call-Out Fees and Diagnostic Charges
Call-out and diagnostic fees vary depending on the time of day, urgency, travel distance, and complexity of the fault.
A typical diagnostic visit may include:
The diagnostic fee may be separate from the repair cost. For example, if the electrician finds water in an outdoor light fitting, the diagnostic visit identifies the issue, while the repair may involve replacing the fitting, resealing penetrations, repairing cable, or upgrading protection.

Why You Should Not DIY This Fault
Electrical faults involving water, repeated tripping, or unknown circuits should never be handled as a DIY project. Opening a switchboard, light fitting, powerpoint, or wall cavity can expose live parts and may make the situation more dangerous.
In NSW, all electrical wiring work must be carried out by a licensed electrician, regardless of the cost or type of work. It is also a breach of the Home Building Act 1989 to carry out electrical wiring work without a licence or certificate.
After completing electrical work, licensed electricians in NSW must provide a uniquely numbered Certificate of Compliance for Electrical Work (CCEW) to show that the work has been tested and complies with the regulations. From 1 July 2026, CCEWs must be submitted through the Building Commission NSW eCert portal; handwritten and PDF forms are no longer accepted.

Sample Message to Send Russo Electrical
You could send the following message when booking:
Hi Russo Electrical,
We have experienced two complete power outages over the past few weeks. During the latest incident last night, there was heavy rain, and the switch at the electrical switchboard kept tripping immediately when we tried to reset it. After turning off some lights, we were eventually able to restore power.
We are concerned there may be an electrical fault, potentially related to rainwater entering an electrical fitting or wiring. Could you please let us know your earliest availability to investigate, along with your call-out fee and diagnostic charges?
The power is currently working, but the affected lighting circuits have been left off. Please let us know whether this requires an emergency call-out or the earliest available diagnostic appointment.
Thank you.
Frequently Asked Questions
Is it safe to keep resetting the tripping switch?
No. If it trips immediately after being reset, stop resetting it. A breaker that will not stay on should be assessed by an electrician.
Can rain really cause a power outage inside my home?
Yes. Rainwater can enter outdoor fittings, roof spaces, wall cavities, underground conduits, or damaged wiring. Water ingress is an emergency electrical situation.
Why did power come back after turning off lights?
The fault may be on one of the lighting circuits or connected fittings. Turning off that circuit may have removed the fault path temporarily, but it does not repair the underlying issue.
Should I use the lights that were switched off?
No. Leave them off until a licensed electrician has inspected and tested the circuit.
What if the power goes out again tonight?
If there are burning smells, smoke, sparks, heat, or water near fittings, treat it as an emergency. Otherwise, switch off the affected circuits, do not repeatedly reset the breaker, and call Russo Electrical for urgent attendance.
Final Thoughts
Two power outages in a few weeks, immediate switchboard tripping, and a pattern linked to heavy rain are strong reasons to arrange an electrical inspection. The fault may involve water entering a fitting or wiring, a damaged lighting circuit, a failing safety switch, or a switchboard issue—but it should be diagnosed properly rather than reset repeatedly.
