The Hidden Cost of Loadshedding | Equipment Failure in South Africa β‘ππ₯
How Loadshedding in South Africa Leads to More Equipment Failures

Driving SD-WAN Adoption in South Africa
Loadshedding has become a grim reality for South African businesses and households. While the immediate frustration of being left in the dark is well understood, an often-overlooked consequence is the increased probability of electronic, networking, and computer equipment failure. Despite the classic IT meme, βHave you tried turning it off and on again?β, the truth is that equipment isnβt designed for constant power cycling. The more frequently devices are powered down and rebooted, the higher the chance of a failure occurring. Add power surges and spikes into the mix, and youβve got a recipe for disaster. ποΈβ οΈπ
The Risks of Constant Power Cycling ππβοΈ
Every time electronic equipment is turned on, it undergoes an inrush currentβan initial surge of electricity required to power up. Over time, repeated exposure to these surges wears down components such as capacitors, power supply units, and even storage devices. Networking gear, routers, and servers are particularly vulnerable, as they are typically designed to operate continuously rather than being switched on and off multiple times per day. ππ»π§
With each loadshedding cycle, the probability of failure increases. Some devices may not power back on at all after an outage, and others may start behaving erratically due to degraded internal components. πβοΈπ
The Dangers of Power Restoration | Surges & Spikes β‘β οΈπ
When Eskom flips the switch back on, a surge of power rushes through the grid. These sudden voltage spikes can damage power supplies, fry delicate circuitry, and, in worst-case scenarios, completely destroy electronic equipment. π₯ππ»
While some may think an Uninterruptible Power Supply (UPS) will solve the problem, most consumer-grade UPS devices are not equipped to handle significant power fluctuations, and they often fail after repeated use. The same applies to surge protectorsβwhile better than nothing, many are incapable of handling high-energy surges over time. π§πβ οΈ
Mitigating the Risks π‘οΈπβ
Since loadshedding isnβt going away anytime soon, businesses and households need to take proactive measures to protect their equipment. π π’π
1. Install a Surge Protector at the Distribution Board (DB) β‘π‘οΈπ
One of the most effective ways to mitigate power surges is to install a surge protector directly at the DB. This provides protection at the source, ensuring that all connected circuits benefit from voltage regulation. βοΈππ
2. Implement a Time-Delay Circuit β³πβ‘
A time-delay switch is an excellent way to reduce the risk of damage when power is restored. Instead of energizing all circuits at once, a time-delay relay ensures that sensitive equipmentβlike networking gear, computers, and serversβonly powers up after a few minutes. This allows voltage levels to stabilize and minimizes inrush current damage. β²οΈππ₯οΈ
3. Use a Manual Load Management Process π οΈπ‘π
In the absence of an automatic time-delay switch, a manual approach can help. Before loadshedding starts, switch off all circuits except for essential lighting. When power returns, allow the lights to stabilize before manually switching on other circuits. While this can be effective, it is also prone to human error, making an automatic solution far more reliable. π€·ββοΈπ‘β οΈ
4. Invest in High-Quality Power Protection Equipment ππ‘οΈπ°
Beyond DB-level protection, businesses should invest in enterprise-grade surge protectors, voltage regulators, and power conditioners. These devices provide an extra layer of security against power fluctuations. ππ§πΎ
5. Monitor & Maintain Equipment Regularly π οΈπ‘π
Frequent power cycles put additional strain on networking and computing equipment. Implementing a proactive maintenance strategyβsuch as checking power supplies, monitoring logs for signs of degradation, and keeping spares on handβcan prevent unexpected failures. ππ‘π
Wrap π¨πβ
Loadshedding isnβt just an inconvenience; itβs a silent killer of electronic equipment. The repetitive cycle of power cuts and restorations significantly increases the risk of hardware failure. By implementing surge protection at the DB, using time-delay circuits, and investing in quality power management equipment, businesses and homeowners can mitigate these risks and ensure their equipment remains operational for as long as possible. π β‘π§
In short, when it comes to protecting your gear, donβt wait until you hear the dreaded click-click... nothing happensβact now to keep your equipment safe! π¨ππ
