Outdoor power points are convenient for powering garden tools, lighting, and appliances, but they face much harsher conditions than indoor outlets. If yours has suddenly stopped working, this guide from Powerhub Electrical in Parramatta will help you understand the possible causes and when it’s time to bring in a licensed electrician.
Outdoor Power Points: What Makes Them Different?
Outdoor power points are designed to endure exposure to sun, rain, humidity, dust, and pests. They are built using weather-resistant materials and must comply with Australian Standards, including having the correct IP rating for dust and water resistance. Without correct installation and regular maintenance, they are more likely to become damaged or unsafe over time.
Common Reasons Outdoor Power Points Stop Working
Outdoor sockets are exposed to the elements, so when they stop working, these are the most likely causes to consider:
Moisture or Water Ingress
Water is the most common enemy of outdoor power points. Rain, irrigation systems, humidity, or even condensation can enter through aging seals or cracked covers. When water gets inside the socket, it can trigger RCD safety switches, cause arcing, or short out the outlet entirely. Left unresolved, it also increases the risk of corrosion and electrical fires.
Tripped Circuit Breaker or Safety Switch
If the outlet suddenly stops working, a tripped breaker or residual current device (RCD) is often the first thing to check. Outdoor outlets are commonly wired into shared circuits with garden lighting, sheds, or external appliances. A fault anywhere on that circuit, such as from a high-powered tool or a sudden power surge, can trigger a shutoff to protect your system.
Loose or Corroded Wiring
Outdoor wiring endures expansion and contraction from temperature changes, as well as moisture buildup, which can cause terminals to loosen or wires to corrode. Corrosion interrupts current flow and makes the socket unreliable or completely dead. In some cases, loose wires can even lead to overheating and present a significant fire risk.
Damaged Socket or Faceplate
Physical damage like cracked plastic, missing screws, or a loose socket exposes the internal wiring to dust, insects, and moisture. Even a small crack can lead to rusted terminals or live parts becoming exposed. If the outlet cover feels brittle or the socket is unstable when plugging something in, it’s likely compromised and needs replacement.
Faulty Appliance or Extension Lead
Sometimes the outlet isn’t to blame. Appliances with damaged plugs, frayed cords, or internal faults can cause the power point to trip or shut off automatically. Using indoor-rated extension leads outdoors is especially risky. They are not sealed against moisture, and their insulation may break down quickly, creating safety hazards every time you plug in. Always test the outlet with a safe, known-working appliance.
Step-by-Step: How to Check a Non-Working Outdoor Power Point
If your outdoor socket has stopped working, follow these safe steps before calling in a licensed electrician:
Step 1: Unplug Any Devices
Start by disconnecting all appliances or cords plugged into the outlet. Leaving anything connected while troubleshooting increases the risk of electric shock or further tripping. Make sure the outlet is completely clear before proceeding.
Step 2: Inspect the Socket Visually
Examine the power point closely for signs of wear and tear. Look for cracks in the faceplate, rust on the terminals, water droplets, or insect debris inside the socket. If there’s any visible damage or moisture present, do not touch it. Leave the cover closed and contact a licensed electrician to avoid risk.
Step 3: Test with a Known Working Device
Plug in a small, low-wattage device like a phone charger or night light that you know works. Avoid using high-draw tools or heaters, as these can overload the circuit. If the test device powers on, the issue might lie with the original appliance or lead. If it doesn’t respond, continue to the next step.
Step 4: Check the Switchboard
Head to your home’s switchboard and look for any tripped circuit breakers or safety switches. Outdoor sockets are usually protected by an RCD. If any switches are in the off position or sitting halfway, reset them after unplugging all outdoor appliances. If the same switch trips again, stop and call a professional.
Step 5: Try Other Power Points
Check other power points around the same area or outside the house. If multiple outlets have lost power, it could be a larger fault with the circuit, a tripped breaker that controls multiple sockets, or an issue in the wiring junctions. Isolating whether it’s a single socket or circuit-wide failure helps narrow down the problem.
Can You Fix an Outdoor Power Point Yourself?
If your outdoor outlet stops working, it may be tempting to attempt a quick fix. Here’s what you can and can’t legally do in Australia:
Legal Restrictions in Australia
It is illegal to repair, replace, or modify any power point in Australia unless you are a licensed electrician. This includes outdoor sockets, even if the issue seems minor. Opening the faceplate, reconnecting wires, or replacing a damaged outlet yourself violates NSW electrical safety regulations and could lead to injury, fire, or fines.
Safe Actions You Can Take
While you must leave electrical repairs to professionals, there are a few safe steps you can take before calling an electrician:
- Unplug all devices from the outlet to avoid additional strain or risk.
- Visually inspect the power point for any signs of damage, such as cracks, water ingress, rust, or burn marks.
- Check your switchboard for tripped breakers or RCDs. If one is tripped, reset it only after all outdoor devices are unplugged.
If the outlet still doesn’t work, avoid further tampering and call a licensed electrician to assess and repair the issue properly. Always prioritise safety when dealing with outdoor electrical faults. Anything beyond this should be left to a licensed electrician.
Preventing Future Outdoor Socket Problems
Outdoor power points face more wear than indoor ones, but with a few preventative measures, you can extend their life and avoid costly issues. Here’s how to keep them safe and functional:
Install Weatherproof Covers (IP Rated)
Use outdoor outlets with an IP66 rating for full protection against dust and water. If the area is partially sheltered, IP53 may be acceptable.
Check and Maintain Regularly
Inspect all outdoor power points every few months, especially after heavy rain or storms. Look for rust, cracked plastic, or failing seals.
Avoid Overloading Circuits
Do not run multiple high-powered garden tools from the same socket. Spread the load across multiple circuits where possible to avoid trips or damage.
Use Outdoor-Rated Appliances and Leads
Only use tools, lights, and extension cords that are specifically designed for outdoor use. Indoor-rated gear can fail quickly when exposed to heat, moisture, or dust.
When to Call a Licensed Electrician
Call Powerhub Electrical if you notice any of the following:
- The outlet still doesn’t work after checking the switchboard
- The socket is cracked, broken, or missing its faceplate
- There’s visible moisture, rust, or insect activity inside the outlet
- Plugging in any device causes an instant trip
- You want to install new outdoor outlets properly and safely
Don’t risk it! Outdoor electrical faults can be dangerous without professional help.

Frequently Asked Questions
Why does my outdoor power point trip the safety switch?
Water ingress or a faulty appliance is usually to blame. Outdoor sockets are more exposed and easily affected by moisture and dust.
Is it safe to use an extension lead outdoors?
Only if it’s outdoor-rated. Using indoor cords outside can result in shock, damage, or fire — especially in wet conditions.
What IP rating should my outdoor socket have?
IP66 is ideal for open outdoor areas. It protects against water jets and dust. IP53 may be okay for covered patios.
Can I install an outdoor socket myself?
No — all power point installations must be done by a licensed electrician. It’s illegal and dangerous to do it yourself.
Why does only my outdoor socket stop working while others are fine?
It may be on a separate circuit or have its own RCD. Faults like water ingress or internal corrosion usually affect only that outlet.
How often should I check outdoor power points?
Inspect every 3 to 6 months, especially after heavy rain, storms, or if you notice power issues when using outdoor appliances.
