Load shedding has become a reality of life in South Africa, but most homeowners don’t realise the serious electrical damage it can cause. Here’s how to protect your home and appliances.
Why Load Shedding Damages Your Electrical System
When power is restored after load shedding, there is often a voltage surge as the grid restabilises. These surges can damage sensitive electronics, trip circuit breakers repeatedly, and over time degrade your DB board and wiring.
1. Install a Surge Protector
A whole-home surge protector installed at your distribution board (DB board) is your first line of defence. It absorbs power spikes before they can reach your appliances. This is one of the best investments a South African homeowner can make.
2. Unplug Sensitive Electronics During Outages
TVs, computers, gaming consoles, and smart devices are especially vulnerable to power surges. Get into the habit of unplugging these before a load shedding slot begins.
3. Use a UPS (Uninterruptible Power Supply)
A UPS provides battery backup and surge protection in one unit. It allows sensitive equipment to shut down safely and protects against voltage fluctuations when power is restored.
4. Have Your DB Board Inspected Annually
Repeated power interruptions cause physical stress on circuit breakers. An annual inspection by a qualified electrician can identify worn breakers, loose connections, or outdated wiring before they become a fire risk.
5. Consider a Solar or Battery Backup System
With load shedding showing no signs of stopping, many South Africans are investing in solar panels and battery storage. Not only does this eliminate the inconvenience of outages, it reduces your electricity bill significantly.
6. Check Your Geyser After Extended Outages
Your electric geyser element is particularly vulnerable. After a long outage, allow the water to heat gradually rather than running multiple high-draw appliances simultaneously, which can trip your breaker or damage the element.
7. Protect Your Gate Motor
Gate motors are frequently damaged during power surges. Ensure yours has a surge protector fitted, and have it serviced regularly — especially if you notice slower operation or unusual sounds after load shedding.
Signs Your Electrical System Has Been Surge-Damaged
- Breakers that trip frequently
- Lights that flicker when appliances switch on
- Burning smell from outlets or the DB board
- Appliances that stop working after a power restore
- Discoloured or warm wall outlets
If you notice any of these signs, don’t delay. Electrical faults are a leading cause of house fires in South Africa.
