Understanding the Reasons Behind Partial Power Loss in Your Home
Experiencing a partial outage in your home can be frustrating and concerning. This situation often arises when a specific section of your electrical switchboard trips, there is a loose neutral connection, or a supply fault impacts just one phase of the electrical system. Additionally, internal wiring issues or faults within the fuse box can contribute to this issue. To accurately identify the source of the problem and ensure safe repairs, it is essential to consult a licensed electrician who can diagnose and rectify the situation properly.
Identifying the Scenario of Partial Power Supply in Your Home
Are you dealing with the peculiar situation where the lights in your living room are shining bright, yet nothing seems to work in the kitchen? Have you lost power to one side of your house? This phenomenon is known as a partial outage, and it is surprisingly common, especially in older homes located in Werribee, Altona, Williamstown, and Laverton, in Melbourne’s western suburbs. Such outages typically indicate an underlying fault in the switchboard, issues with internal wiring, or complications related to the supply feed from the street.
In this article, we will explore the various causes of this problem, outline what aspects you can safely check, and explain when it is essential to call in professional help.
Exploring the Most Frequent Causes of Partial Power Loss in Homes
Here are some of the most common culprits behind a partial power loss:
Identifying a Tripped Circuit Breaker
When one circuit breaker flips while others remain operational, only a portion of your home experiences a loss of power. This often happens due to:
- A circuit being overloaded with too many appliances
- An electrical appliance malfunctioning
- The presence of a short circuit in lights or outlets
Understanding the Impact of a Faulty RCD or Fuse
A malfunctioning safety switch or a blown fuse can isolate specific parts of your electrical system. In such instances, you might find that you have lights working in some areas but no power points available, or vice versa, leading to an inconvenient situation.
Recognising the Dangers of a Loose Neutral Connection
A loose or broken neutral connection, whether it exists in the switchboard or the mains supply, presents a more serious issue. Such a condition results in uneven voltage distribution across circuits, causing lights to flicker, surge, or blow out entirely. Additionally, this can lead to rapid damage to your appliances, creating a risk that cannot be overlooked.
Assessing Supply Issues from the Street
In certain areas, power is delivered across two distinct “phases.” If one phase fails, it results in a power outage for half of the home. Often, the root cause of this problem lies in a fault with the pole fuse or a broader supply issue affecting your street.
Steps You Can Take to Safely Investigate the Issue
- Examine your switchboard. Is there a breaker or safety switch that is turned off while others remain on?
- Attempt to reset the breaker. If it clicks back on and stays operational, you may be in the clear.
- If the breaker trips again immediately, leave it off and disconnect everything connected to that circuit.
- Check with your neighbours to see if they are experiencing a similar issue—it could indicate a street-level outage.
It is crucial not to open or remove any components in the switchboard. Instead, reach out to us, and we will safely isolate the fault to ensure your home's safety.

Recognising the Dangers Associated with Partial Power Outages
While partial outages may seem less urgent than a total blackout, they can often present greater risks. Signs of a serious fault include:
- Lights dimming or becoming excessively bright when appliances are activated
- Unusual buzzing or crackling sounds emanating from the switchboard
- A burning smell or heat coming from power points
- Flickering LED lights or lights that fail unexpectedly
These symptoms may indicate a faulty neutral connection or a high resistance fault, which significantly increases the risk of fire and can cause damage to your appliances or even your electricity meter.

Frequently Asked Questions About Partial Power Outages
Why Is Only Half of My House Experiencing Power Loss?
The reason only half of your house may lose power is that different areas of the home are connected to separate electrical circuits. If one of these circuits trips or fails, the other circuits may still function normally.
Can I Continue to Reset the Switch?
No, it is not advisable to keep resetting the switch. If it continues to trip, there is an underlying fault that needs to be tested. Repeated resets can obscure the issue or potentially cause further damage to the electrical system.
Is This Issue Related to Powercor?
It is possible that this may be a Powercor issue. If there is a fault on the supply side, we have the capability to test the feed and coordinate with Powercor as necessary.
Do You Provide After-Hours Services?
Absolutely! We offer emergency electrical services 24 hours a day, seven days a week, throughout Melbourne’s western suburbs.
