Electrical systems are powerful and a part of our everyday lives. They also need the right protections to keep your home safe and functional.
Occasionally, power surges occur, causing the electrical voltage to exceed the circuit’s capacity. This overload can cause damage to appliances and degrade your system over time. This is where surge protectors come in!
Surge protectors are safety devices designed to protect your electronics from power surges. They detect excess voltage during a spike and either divert the power surge or absorb it, keeping it from reaching your appliances or causing severe damage to your system.
Reach out to Electricians Sydney by Alliance (ESBA) to have a surge protection device (SPD) installed so you can rest easy knowing you’re protected during power outages, lightning storms, and other power surge-prone times.
ESBA operates Sydney-wide and offers a lifetime workmanship warranty and 100% service satisfaction guarantee, so by the end of our work, you know you’ll be happy!

Surges are fluctuations in the flow of electricity through your system, causing a surplus of power to travel along circuitry and wiring. There are two types of surges in electrical systems: Internal and External.
External surges come from outside an electrical system and interfere with the current’s flow. While external surges are less common than internal ones, they carry a significantly higher voltage and are more likely to damage appliances and your electrical systems. The most common causes of external surges are:
Surges of any kind can be dangerous and can cause:
Internal surges come from an internal source of an established electrical system. Internal surges account for 60-80% of surges in homes and businesses and generally occur silently throughout the day. Even so, they can damage equipment and your system, especially over time. Common causes are:
When it comes to your options for surge protection, there are two ways to approach it. You can install a whole-house surge protector or a point-of-use surge protector. Both are effective and often used in tandem with one another.
| Whole-Home Surge Protection | Point-of-Use Surge Protection | |
| How it Works | A device installed directly into your switchboard that protects the entire system from surges, particularly in the case of major external surges. The SPD intercepts the spike before it enters the building’s wiring, absorbing the power or diverting it. | A device, usually a powerboard or adapters, that plugs directly into individual outlets to protect appliances and devices against surges. These devices use Metal Oxide Varistors (MOVs) or Gas Discharge Tubes (GDTs) to absorb the excess energy and divert it to the grounding wire. Primarily, these are used for smaller voltage spikes. |
| Benefits |
|
|
| Cost | $70-$300 (device only) | $20-$100 |
| Considerations | You will need a licensed electrician to conduct any installation processes and a proper grounding system. | Cannot protect major appliances and will need to be replaced over time or if a severe power surge occurs. |
The best way to protect your home and belongings is to have dedicated components integrated into your electrical system to shield you from everyday power fluctuations and unpredictable external surges.

There are four types of Surge protection devices (SPDs), with each serving a specific purpose :
Type 1 and Type 2 SPDs are the most important whole-house surge protectors and the most commonly used in business and residential buildings. They work with your property’s equipotential bonding to prevent overvoltage.
Protecting sensitive electronics in your home is straightforward when you know how. Be sure to have:
A UPS is a device that provides an instant battery backup for computers, servers, and network modems and surge protection during a blackout. ESBA recommends a UPS that provides at least 15 minutes of power, so you can safely shut down your devices and save important files. If you’re unsure of what UPS to choose, ESBA is available for consultation on:

Household insurance for surge damage is typically included in Home and Contents Insurance and provides coverage for damage to wiring and appliances during power surges. However, there are limitations to this kind of insurance when it comes to surge damage, including:
To have proper protection for your home with full peace of mind, it’s best to have safeguards like surge protectors set in place so you don’t have to deal with complicated insurance claims in the first place.
At ESBA, we take your home’s safety seriously. That’s why we provide an end-to-end process for our surge protector installations:
We always begin with a home inspection of your electrical system to understand what we’re working with. We’ll also ensure your property’s electrical system is safe to work on.
After our inspections, we’ll talk you through our recommendations for what whole-house protectors we recommend and whether a UPS is necessary.
Before any work begins, you’ll receive a written quote and a full explanation of the extent of the work. We won’t start until you sign off.
After you give us the OK, we’ll get to work connecting the SPDs to your switchboard and connecting all the appropriate wires to your system.
After everything is installed, we’ll test your new SPD and make sure it’s in working order.
At Electricians Sydney by Alliance, we have a 100% service satisfaction guarantee and a lifetime workmanship warranty. That means we won’t stop working until you’re happy with our work.

Surge protection is not mandatory for residential properties. However, surge protection is recommended to protect your home from critical damage and is required by most electrical home installations like solar power systems or residential batteries.
The cost of a surge protection installation will depend on the type of SPD being installed and whether it is attached to a specific piece of equipment. Generally, a surge protector installation for residential properties will cost between $500 and $800, but can be as little as $350 and as high as $1,500. The easiest way to establish a precise cost is to get a quote.
