We’ll clear up some common misconceptions about whether they protect you from nasty electric shocks (spoiler alert - they don’t - that’s your circuit breakers’ job).
Most importantly, we’ll walk through smart surge protection strategies you can use today to create a safe space for all your tech gear. Knowledge is power when it comes to avoiding catastrophic cases of surge-slaughtered devices.
By the end, you’ll be ready to arm your electrical system and send those voltage villains running. Let’s banish the threat of zapped gadgets and keep your gear at peak performance.
A power surge is a sudden and significant increase in voltage that can damage, deteriorate, or destroy the electronic equipment plugged into your outlets. Common causes of power surges include:
Power surges can inflict havoc on electrical appliances, potentially leading to electrical fires if not appropriately managed.
Surge protection devices (SPDs) are designed to protect electronic equipment from excess voltage caused by power surges. These devices divert the extra electricity from the connected devices, preventing damage.
Surge protectors work by utilising specialised internal components that rapidly detect and respond to sudden spikes in voltage. One key component is a metal oxide varistor (MOV). MOVs are designed to identify increases in voltage above normal levels. When they detect a surge, they act like a pressure release valve - instantly short-circuiting the excess electricity straight to the ground wire before it can reach your electronics.
Other components like gas discharge tubes and thermally activated fuses also provide backup layers of protection. They all work together to shunt potentially hazardous surges safely away from devices. The goal is to clamp the excess incoming voltage to a regulated, harmless threshold before it passes through to your equipment.
Quality surge protectors can react incredibly quickly, diverting surges in mere billionths of a second. This prevents connected devices from seeing spiked voltage levels that could damage their sensitive internal components.
In simple terms, surge protectors rapidly short-circuit electricity exceeding safe levels, keeping only average voltage flowing to the outlet. This safeguards your gadgets from surges that could otherwise degrade or destroy them, resulting in protected and properly functioning tech.
A common question is whether a surge protector can prevent electrocution. While surge protectors are adept at handling overvoltage, it’s crucial to understand that they are not designed primarily to avoid electric shock.
Devices like residual current devices (RCDs) are specifically tailored for this purpose. They provide overcurrent protection and prevent electrocution by detecting earth leakage.
There are a few common types of surge protection used in Australian homes and businesses:
Ideally, a multilayered approach combines hard-wired whole-house defence with secondary protection methods for the most vulnerable gear. This provides complete, overlapping fortification tailored for Australian conditions.
Surge protectors should be professionally installed and integrated with your existing safety systems for the best protection against electrical surges. Most Australian homes already contain safety measures like residual current devices (RCDs), ground fault circuit interrupters, and circuit breakers, which work by cutting power when an electrical fault is detected.
Surge protectors provide an additional layer of defence by diverting excess voltage before reaching connected equipment like your TV, computer or kitchen appliances. Hard-wired, whole-home surge protectors installed at your switchboard ensure all wiring and outlets have adequate protection. More vulnerable devices can also benefit from point-of-use surge strips plugged directly into wall outlets.
Safety switches and surge diversion technology provide robust, compliant fortification against dangerous voltage spikes when layered together correctly. This prevents fires, equipment damage, and other electrical disasters that surges can cause.
For worry-free protection tuned for Australian installations, have an electrician assess your situation and integrate the right surge solutions into your existing infrastructure. This provides comprehensive, seamless guarding tailored for your home and family.
Daily, we depend on workhorse appliances like refrigerators, ovens, and air conditioners. But did you know that cycling these heavy-duty devices on and off can generate power surges back into your home’s electrical system?
When switched on, appliances’ compressors and motors draw huge bursts of current. This can stress your wiring and cause voltage spikes that damage other sensitive electronics and appliances. It becomes a vicious cycle—without protection, surges degrade appliances faster, leading to even more harmful spikes.
Large appliances benefit greatly from industrial-grade surge protectors explicitly designed for their high wattage demands. Protectors sized for air conditioner or refrigerator circuits help suppress the nasty surges they produce, allowing them to turn on smoothly. This defence also shields the units from external spikes travelling in, extending appliance lifespans.
Lightning strikes can induce power surges that are catastrophic to electronic equipment. Direct lightning strike protection requires a specialised setup, as the energy involved in a lightning hit is immense. Surge protectors can offer a first line of defence, but it is often recommended to unplug sensitive electronics entirely during lightning storms.
Installing surge protectors is just the first step - maintaining your system is crucial for long-term performance. While quality surge diverters are designed for years of use, they degrade over time.
Always periodically check protectors for any physical damage or scorch marks that indicate they’ve been overwhelmed. Most units have indicator lights that flicker off when components need replacing.
Additionally, routinely replace all surge suppressors every 3-5 years as an essential precaution to account for gradual wear. Don’t wait for a spike event or failure - proactively swapping depleted equipment ensures your safety net remains intact. Also, replace any protector immediately if it has blocked a significant, high-energy surge from reaching your devices - even if it still works. Its protective elements have likely used up their designed lifespan in that scenario.
Investing a few minutes in occasional inspections and routine system updates keeps your protectors in prime health. This simple maintenance lets them reliably divert hazardous voltage, preventing expensive gadget damage and potential electrical fires. Think of it like changing the oil in your car—regular proactive care means your system will keep you protected for years to come.
Surge protectors play a vital role in our daily lives, shielding our homes and devices from the potential dangers of power surges. However, they should be part of a larger safety system that includes RCD and circuit breakers to prevent electrocution and protect against electrical faults.
Understanding and implementing the right surge protection strategy can enhance the longevity of your appliances and ensure your household’s safety.
As you contemplate the health of your home’s electrical system, consider consulting with a professional electrician to evaluate your surge protection needs and ensure that your setup is up to date. If you are in Melbourne, speak with our electrical experts at WP Electrical!
An RCD monitors for electrical current leakage and cuts power to prevent shocks. A surge suppressor diverts electrical surges to protect electronic equipment from voltage spikes, usually caused by events like fallen power lines. RCDs focus on human safety, while surge suppressors focus on equipment protection.
Check if it’s labelled as a surge suppressor or surge protector. Suppressors contain components like metal oxide varistors that divert excess electricity. Most power strips only extend outlets without diverting surges, providing no extra protection during events causing electrical surges.
Not necessarily. Electric generators can produce "dirty power" with more voltage spikes than standard wall outlets. Some lower-end surge suppressors may struggle with these irregular surges. Invest in industrial-grade suppressors explicitly designed for generators to ensure proper protection of electronic equipment.
Possibly. Frequent tripping can result from electrical surges overloading wires and triggering safety devices. Surge suppressors installed at your switchboard shunt excess electricity before it reaches circuits and causes issues. Suppressors provide extra defence while letting safety features like RCDs and breakers do their core job of preventing fires and shocks.
Power outages can occur for a variety of reasons. Severe weather, animals, vegetation, equipment failure, and human error are the most prevalent causes of electrical blackouts. Understanding what triggers outages can help you prepare and respond appropriately.
