7 Common Electrical Defects Found in Strata Complexes
7 Common Electrical Defects Found in Strata Complexes.
Strata complexes play a critical role in providing safe, comfortable living environments for tenants and owners alike. With multiple dwellings sharing infrastructure and services, electrical systems in strata properties carry extra pressure — and when things go wrong, the consequences can be costly, inconvenient, and even dangerous.
At Spectra Electrical, we’ve worked with dozens of strata-managed properties across Sydney, and we’ve seen firsthand how electrical defects — if left unchecked — can lead to compliance issues, fire risks, and unhappy residents.
Here are 7 of the most common electrical defects we find in strata complexes — and what you can do to prevent them.
1. Non-Compliant or Outdated Switchboards
One of the most frequent electrical issues in older strata buildings is the presence of outdated or non-compliant switchboards. Many still operate with old fuse systems, lack safety switches (RCDs), and aren’t capable of handling modern electrical loads.
Why it’s a problem:
- No RCDs = higher risk of electric shock or fire
- Increased chances of tripped circuits due to overload
- Can lead to defects during insurance or compliance inspections
How to fix it:
- Engage a licensed electrician to inspect and test all switchboards
- Upgrade to modern circuit breakers and safety switches
- Ensure switchboards are clearly labelled and securely housed
Spectra Electrical can provide strata-wide switchboard assessments and staged upgrades to minimise disruption.
2. Overloaded Circuits
With residents using more appliances, air conditioning, EV chargers, and technology than ever before, electrical circuits are often pushed beyond their original design limits. This is especially common in older strata buildings where infrastructure hasn’t been updated.
Warning signs:
- Circuit breakers constantly tripping
- Flickering lights or power fluctuations
- Heat coming from power points or switchboards
Prevention:
- Conduct a load capacity review to ensure demand matches supply
- Add dedicated circuits for high-load areas (e.g. common areas, lifts, HVAC)
- Schedule regular maintenance to spot potential overloads early

3. Inadequate or Non-Functional Emergency & Exit Lighting
Strata complexes are legally required to have functional emergency and exit lighting in common areas — but many buildings fall behind in maintaining or testing these systems.
Risks:
- Non-compliance with Australian Standards (AS/NZS 2293)
- Reduced visibility during blackouts or evacuations
- Increased liability for body corporate in case of emergencies
Solution:
- Set up a 6-monthly emergency lighting test log as required by law
- Replace non-functioning fittings and batteries
- Upgrade to LED emergency lighting for better performance and lower maintenance
Spectra offers emergency lighting compliance services, including testing, repairs, and ongoing reporting for strata managers.
4. Damaged or Aged Wiring
Wiring hidden behind walls and ceilings doesn’t last forever. In strata buildings over 20 years old, electrical cabling can become brittle, frayed, or corroded, increasing the risk of faults or fire.
Common signs:
- Unusual smells from outlets
- Intermittent power loss in specific areas
- Sparks or visible damage when using power points
Prevention:
- Carry out thermal imaging scans and insulation resistance tests
- Replace aged or unsafe wiring during renovations or upgrades
- Ensure wiring is compliant with current codes and capacity needs
5. Unmaintained Power points and Light Switches in Common Areas
In high-traffic zones like stairwells, car parks, and lobbies, electrical outlets and switches are often subject to wear, impact, and misuse. Over time, they become loose, cracked, or non-functional.
Risks:
- Electrical shock to residents or visitors
- Code violations for accessibility or safety standards
- Frustrated residents due to lighting or power failures
What to do:
- Include regular visual inspections of all common-area electrical fittings
- Upgrade damaged fittings to tamper-resistant or weatherproof units
- Use commercial-grade components for durability
6. Improperly Installed or DIY Electrical Work
Strata properties often undergo upgrades or maintenance by different trades over time — but not all electrical work is done properly. We frequently find unlicensed or DIY wiring, especially in older or self-managed buildings.
Issues this can cause:
- Voided insurance policies
- Fire hazards from unsafe connections
- Hidden defects that are hard to trace until they fail
How to address it:
- Conduct a comprehensive electrical safety audit
- Ensure all future works are completed by licensed electricians
- Document and register all electrical installations with the relevant authorities
Spectra Electrical ensures all work is fully compliant and backed by certificates of electrical safety (CES).
7. Insufficient Lighting in Car Parks and Outdoor Common Areas
Strata complexes are responsible for providing safe lighting in shared spaces, especially car parks, pathways, and entryways. Poor or insufficient lighting can increase the risk of:
- Trips and falls
- Break-ins or vandalism
- Resident complaints and legal liability
Solutions:
- Upgrade to LED motion sensor lighting for energy savings and improved visibility
- Conduct night audits to identify underlit zones
- Automate lighting schedules based on time or occupancy
Spectra can design and install strata lighting solutions that are cost-effective, energy-efficient, and compliant with local council guidelines.
Final Thoughts: Preventing Electrical Defects in Strata is Easier Than Fixing Them
Electrical defects in strata complexes don’t just impact safety — they affect resident satisfaction, insurance compliance, and the property’s long-term value. By addressing these 7 common electrical defects found in strata complexes, strata managers can:
- Avoid expensive emergency callouts
- Stay ahead of compliance requirements
- Keep tenants safe, happy, and informed
