Power Keeps Tripping? What It Means and What to Do Next
- Luke Herman
If your power keeps tripping, it is more than just an inconvenience. Repeated power tripping is your electrical system’s way of signalling that something is wrong, and continuing to reset the switchboard without understanding the cause can put your home at risk.
In Perth homes, power tripping is commonly linked to overloaded circuits, faulty appliances, earth faults, deteriorating wiring or problems within the switchboard itself. While some causes are minor, others can indicate serious electrical faults that should not be ignored.
This guide explains why electricity keeps tripping, what it usually means, when it becomes dangerous, and when it is time to call an electrician.

What happens when your power trips?
When your power trips, a safety device within your switchboard shuts off electricity to part or all of your home. This device may be a circuit breaker, RCD or fuse, depending on the age and setup of your electrical system.
Power tripping occurs when the system detects too much electrical load, a short circuit, an earth fault or unsafe current flow. The purpose of this shut-off is to prevent damage, overheating or electric shock.
Occasional tripping can happen, but frequent or unexplained tripping should always be investigated.
Why does my power keep tripping?
If your power keeps tripping, there is usually an underlying fault rather than a random issue. The most common causes electricians see in Perth homes include the following.
Overloaded circuits
Overloaded circuits are one of the most common reasons electricity keeps tripping, particularly in older homes.
Each circuit is designed to carry a specific electrical load. When too many high-power appliances run on the same circuit, the breaker trips to prevent overheating. This often happens with heaters, air conditioners, ovens, cooktops or multiple appliances connected through power boards.
If power tripping occurs at the same time of day or when certain appliances are running, circuit overload is a strong possibility.
Faulty appliances
A single faulty appliance can cause ongoing power tripping, even if everything else appears normal.
Appliances with damaged cords, internal faults or moisture damage can leak current and trigger safety devices. If your breaker trips when a specific appliance is plugged in or switched on, stop using it immediately and have it checked.
Earth faults
Earth faults occur when electricity escapes its intended path and travels through the ground or surrounding materials. This is particularly dangerous because it increases the risk of electric shock.
RCDs are designed to detect earth faults and cut power instantly. If your power breaker keeps tripping and will not stay on, an earth fault is a likely cause and should be addressed urgently.
Loose or deteriorating wiring
Loose wiring is a serious cause of repeated power tripping and is often found in older Perth homes or properties with poor previous electrical work.
Loose connections can cause intermittent power loss, heat build-up, arcing behind walls and increased fire risk. This type of fault cannot be safely diagnosed without professional testing and should never be ignored.
Switchboard or breaker faults
Sometimes the issue is not the wiring or appliances but the safety device itself.
Old or worn circuit breakers can trip unnecessarily or fail to handle normal electrical loads, particularly in switchboards that have not been updated to suit modern usage. Repeated tripping can also point to issues within the switchboard, especially when RCDs and circuit breakers are ageing or no longer responding accurately to faults.
If a breaker trips with nothing plugged in or will not stay reset, the switchboard may need inspection, testing or upgrading by a licensed electrician.
Why does my power keep tripping with nothing plugged in?
When electricity keeps tripping with nothing plugged in, the cause is almost always within the fixed electrical system rather than anything you are using day to day.
Common causes include earth faults in wiring, deteriorated insulation, moisture ingress, failing circuit breakers or wiring faults hidden behind walls, ceilings or within the switchboard itself. These issues can develop gradually and are often not visible, which is why power tripping can seem random or unexplained.
Resetting the breaker repeatedly will not resolve these faults and can place additional stress on the electrical system over time. Professional testing is required to safely locate the source of the problem, confirm whether wiring or switchboard components are involved, and prevent the issue from escalating. This is where an experienced electrician, such as our team at P Herman & Co, can identify the fault accurately and ensure the system is made safe.
Is it dangerous if my power keeps tripping?
Yes, it can be.
While circuit breakers are designed to protect your home, repeated power tripping is often a warning sign, not a solution. Ongoing tripping may indicate overheating wiring, electrical arcing, increased fire risk or electric shock hazards.
If you notice burning smells, warm switch plates, buzzing sounds or scorch marks, stop using the affected circuit and arrange an inspection immediately.
A preventative electrical safety check can identify risks before they escalate.
What should I do when my breaker keeps tripping?
If your power breaker keeps tripping, follow these steps:
- Turn off or unplug appliances on the affected circuit to reduce electrical load.
- Reset the breaker fully to the off position, then switch it back on.
- Reconnect appliances one at a time, watching to see if the breaker trips again.
If the breaker trips again, stop resetting it. Repeated tripping indicates an underlying fault that requires professional testing. At this point, it is safest to contact our team at P Herman & Co to inspect the circuit, identify the cause and ensure your electrical system is operating safely.
Never force a breaker to stay on. If it continues to trip, it is doing its job by protecting your home.
Can I fix power tripping myself?
In some cases, very minor issues related to electrical load can be managed without professional help. For example, if your power trips only when several high-power appliances are running at the same time, redistributing those appliances across different circuits may reduce the load and prevent further tripping.
However, repeated power tripping is rarely caused by a simple overload alone. Faults involving wiring, switchboards, earth leakage, moisture ingress or failing safety devices cannot be identified or repaired safely without specialist testing equipment. These types of issues often sit behind walls, ceilings or inside the switchboard and are not visible to the homeowner.
Attempting to diagnose or repair electrical faults yourself can increase the risk of electric shock, equipment damage or fire, particularly if the underlying issue involves deteriorated wiring or earth faults. If your breaker continues to trip after basic load checks, or trips with nothing plugged in, a licensed electrician is required to locate and fix the cause safely.
How to reduce the risk of power tripping
To reduce the likelihood of ongoing power tripping:
- Avoid overloading power boards.
- Replace damaged or faulty appliances.
- Spread high-power devices across different circuits.
- Schedule regular electrical inspections.
- Upgrade outdated switchboards where necessary.
Older homes, in particular, may not be designed to handle modern electrical demand and often benefit from professional upgrades.
When to call an electrician for power tripping
If your power keeps tripping, especially without a clear cause, it is time to call an electrician.
Persistent tripping, tripping with nothing plugged in, burning smells or breakers that will not reset safely all indicate faults that require professional attention. Identifying and fixing the cause early helps prevent damage, safety risks and unexpected outages.
P Herman & Co can assess why your power keeps tripping, identify the underlying fault and ensure your electrical system is safe, compliant and reliable.
