A Cape Town Homeowner’s Autumn Preparedness Guide
As autumn settles over Cape Town, residents face a dual challenge: preparing for winter while bracing for Eskom’s relentless load shedding. What many don’t realize is that the constant power cuts aren’t just inconvenient—these electrical hazards are actively damaging home electrical systems in ways that become dangerous when winter arrives.
At Electrogem, we’ve responded to countless emergency calls caused by load shedding electrical hazards that could have been prevented with proper autumn maintenance. This guide reveals the hidden risks and provides actionable solutions to protect your home.
Why Autumn Load Shedding Poses Unique Risks
Cape Town’s autumn creates the perfect storm for electrical hazards:
- Increased Moisture: Damp weather corrodes exposed wiring and connections
- Temperature Swings: Expanding/contracting components loosen electrical contacts
- Higher Demand: Families start using heaters, putting strain on already compromised systems
Most homeowners only realize their electrical system has been damaged by load shedding when winter storms hit. By then, repairs cost significantly more.
5 Silent Ways Load Shedding is Damaging Your Home
1. The Geyser Time Bomb
Repeated power cycling during load shedding causes:
- Thermal stress that cracks heating elements
- Limescale buildup from inconsistent temperatures
- Premature failure (often at 2-3 AM when power returns)
Solution: Install a geyser timer or delay switch (requires a Cape Town electrician)
2. Flickering Lights = Looming Danger
That subtle flicker when power returns signals:
- Loose connections in your electrical distribution board
- Failing circuit breakers
- Voltage fluctuations damaging sensitive electronics
3. Surge Damage You Can’t See
Most surge protectors fail after 2-3 major surges. Load shedding causes:
- Silent damage to appliance circuit boards
- Gradual degradation of wiring insulation
- “Walking wounded” electronics that fail months later
Professional Fix: Whole-house surge protection (not just plug strips)
4. Solar System Sabotage
Solar PV system load shedding creates unique issues:
- Battery memory effect from partial discharges
- Inverter stress during frequent grid reconnections
- Reduced lifespan from constant cycling
5. The Generator Trap
Improper backup generator use causes:
- Backfeeding that damages neighborhood transformers
- Carbon monoxide buildup in enclosed spaces
- Fuel system fires from improper storage
Professional Protection Only Electricians Provide
While some issues are DIY-detectable, these solutions require certified Cape Town electrical contractors:
- Distribution Board Upgrades
- Install load-shedding-ready breakers
- Add voltage monitoring relays
- Earthing and Lightning Protection
- Critical for solar systems during storms
- Prevents surge damage when power returns
- Electrical Fault Finding
- Thermal imaging detects hot spots
- Megger testing reveals insulation breakdown
Most homes built before 2015 need upgrades to handle modern load shedding. A few strategic improvements to prevent these electrical hazards can save thousands in damage.

Solar Owners: Special Autumn Maintenance
If you have a solar PV system, add these steps:
- Clean panels of autumn leaves/debris
- Test battery capacity (cold weather reduces output)
- Verify isolation switches work properly
- Ensure earthing and lightning protection is intact
When to Call Electrogem Immediately
Don’t ignore these warning signs:
- Burning plastic smells from outlets
- Sparks when power returns
- Circuit breakers that won’t reset
- Electronics failing mysteriously
