Electrical systems in Sydney homes must follow strict codes and standards to ensure safety and reliability. However, older properties and even some newer renovations often contain wiring or installation issues that don’t meet current requirements. While some violations may seem minor, they can create fire hazards, cause electrocution risks, or lead to costly damage if left unresolved.
Below are seven of the most common electrical code violations found in Sydney homes, why they matter, and how you can fix them with the help of a licensed Level 2 electrician.
1. Overcrowded Junction Boxes
The Problem: Why You Need to Fix Overcrowded Junction Boxes
When too many wires are crammed into a junction box, overheating and short circuits become a real risk. It also makes future repairs harder and more dangerous.
Code Requirements
AS/NZS 3000 (Wiring Rules) requires junction boxes to be sized correctly for the number of conductors, devices, and fittings inside. The box must provide enough space so that wires aren’t bent sharply or compressed.
How Eris Electrical Can Help You Solve Such Boxes
The team at Eris Electrical can inspect your junction boxes, calculate the required box size, and replace undersized ones with compliant fittings. This eliminates fire risks and keeps your wiring safe for future use.
2. Exposed or Damaged Wiring
The Problem: Why You Need to Fix Damaged Wiring
Exposed or frayed wires pose a serious electrocution hazard and increase the likelihood of fire. Many Sydney homes, especially older ones, still have damaged insulation or wires left unprotected in high-traffic areas.
Code Requirements
AS/NZS 3000 requires that all wiring must be insulated and mechanically protected. Cables running along walls or through roof cavities must be sheathed and secured.
How Eris Electrical Can Help You Solve Exposed Wiring
Eris Electrical provides thorough rewiring services, replacing old or unsafe cables with new, compliant wiring. They can also reroute or protect exposed wires with conduits, making your home much safer.
3. Incorrect Circuit Breaker Sizes
The Problem: Why You Need to Have the Correct Sizes
A breaker that’s too large for the circuit wiring won’t trip when it should, which can overheat wires and lead to fire. On the other hand, a breaker that’s too small causes constant nuisance tripping.
Code Requirements
Under AS/NZS 3000, circuit breakers must be matched to the conductor size and load of the circuit. Each circuit needs overcurrent protection appropriate to the appliances it powers.
How Eris Electrical Can Help You Solve the Switchboard Issue
Eris Electrical electricians can review your switchboard, identify mismatched breakers, and install the correct ratings. They can also upgrade your switchboard if necessary to bring it in line with current standards.
4. Missing or Faulty RCDs (Safety Switches)
The Problem: Why You Need to Fix RCSs
Residual Current Devices (RCDs) save lives. Without them, a small fault can become fatal. Unfortunately, many older Sydney homes still don’t have safety switches on every circuit.
Code Requirements
AS/NZS 3000 requires RCDs to be installed on all final subcircuits in residential properties. This includes lighting, power, and even hot water circuits.
How Eris Electrical Can Help You Solve This
Eris Electrical can install new safety switches across all circuits in your home. If you already have them, they can test and replace any faulty RCDs so you and your family remain protected.
5. Illegal DIY Electrical Work
The Problem: Why You Need to Fix It
DIY wiring is one of the most dangerous violations. Work carried out by unlicensed individuals often doesn’t comply with standards and may create hidden risks. Homeowners can face fines or insurance claim denials if DIY wiring causes damage.
Code Requirements
In NSW, only licensed level 2 electricians are permitted to carry out electrical work. All installations and alterations must meet AS/NZS 3000 standards and be certified by a licensed professional.
How can a Level 2 Electrician Professional Help you here?
If you suspect your home has DIY wiring, Eris Electrical can perform a compliance inspection. They’ll correct unsafe work, certify the system, and ensure your property meets all legal requirements.
6. Lack of Earthing or Bonding
The Problem: Why You Need to Fix Earthing
Earthing is crucial for safety. Without it, fault currents have nowhere to go, greatly increasing the risk of electric shock. Older homes often lack proper earthing or bonding on pipes, water heaters, or metal fixtures.
Code Requirements
AS/NZS 3000 requires all electrical installations to be earthed. Bonding of conductive parts, such as metal plumbing, is also mandatory to ensure safety.
How Eris Electrical Can Help You Solve Earthing Issues
Eris Electrical can test your earthing system and upgrade it to meet current codes. They can install proper earth stakes, ensure main earth cables are intact, and bond metallic systems as required.
7. Overloaded Power Boards and Circuits
The Problem: Why You Need to Fix the Overloaded Board
Plugging too many appliances into one power board or circuit can overload the system, causing overheating and potential fire hazards. This issue is common in homes with limited outlets or older wiring.
Code Requirements
AS/NZS 3000 specifies that circuits must be designed for the expected load. Using multiple double adaptors or power boards is not a compliant solution. Permanent outlets and additional circuits must be installed instead.
How Eris Electrical Can Help You Solve Such Circuits
Eris Electrical can install additional outlets and circuits to spread the load safely. They’ll also assess your switchboard to ensure it can handle the demand of modern households.

Electrical code violations aren’t just about ticking boxes; they’re about keeping your home and family safe. From overloaded circuits to missing safety switches, these issues can quickly escalate into serious hazards if ignored.
