Surge Protection and How It Safeguards Electrical Systems

Surge protection is designed to shield electrical systems from sudden voltage spikes caused by lightning, power grid switching, or internal electrical faults. Better Electrical Co repairs and replaces surge protectors that divert excess voltage away from circuits before it reaches appliances and sensitive equipment.

When functioning correctly, surge protection improves system stability and significantly reduces the risk of damage to electronics. When surge protection fails, however, voltage spikes can pass directly through the electrical system, increasing the likelihood of appliance failure, data loss, or switchboard damage.

Modern homes in the Sutherland Shire are particularly reliant on effective power surge protector systems due to the number of electronic devices now connected to household wiring.

Why Surge Protection Devices Fail Over Time

Surge protection devices do not last forever. Each time a surge protector absorbs excess voltage, its internal components degrade slightly. Over time, this wear reduces the device’s ability to provide protection.

Common reasons surge protection devices fail include:

Lightning strikes or storm-related electrical activity
Power grid fluctuations and switching events
Repeated minor surges over time
Age-related degradation of internal components
Incorrect installation or undersized devices

Once a power surge protector has failed, it can no longer protect the electrical system and should be repaired or replaced promptly.

Signs Surge Protection May No Longer Be Working

Surge protection often fails silently, meaning there may be no obvious indication that protection has been lost. Better Electrical Co regularly identifies failed surge protectors during inspections or after appliance damage has occurred.

Warning signs may include indicator lights showing a fault, recent unexplained damage to appliances, power disturbances during storms, or outdated surge protection devices within the switchboard. Properties without modern surge protection installed on updated switchboards are also at increased risk.

An electrical inspection confirms whether surge protection is still effective or requires attention.

Surge Protection Within the Switchboard

Surge protection is typically installed within or directly connected to the switchboard, providing protection across all circuits rather than individual outlets. Because of this, faults in surge protection can affect the entire electrical system.

Repairs involve safe isolation of power, inspection of the surge device, and testing after repair or replacement. In some cases, surge protection repair is carried out alongside switchboard upgrades to improve overall protection and bring the system in line with current standards.

This is particularly common in older homes across the Sutherland Shire that have had partial electrical upgrades over time.

Repair vs Replacement of Surge Protection Devices

Better Electrical Co assesses whether surge protection devices can be repaired or require replacement. In most cases, replacement is recommended rather than repair, as internal components degrade permanently once they have absorbed multiple surges.

Replacement is usually required when the device has reached the end of its service life, internal components are damaged, or the device no longer meets current compliance requirements. Replacing failed power surge protectors restores full protection across the property and reduces future risk.

Repeated Power Surges and Underlying Electrical Issues

Frequent power surges may indicate broader electrical problems rather than isolated external events. Better Electrical Co investigates repeated surge events to determine whether faults exist within wiring, connections, or switchboard components.

Repeated surges can be linked to loose or deteriorated connections, aging electrical infrastructure, internal faults, or unstable supply conditions. In these cases, surge protection repair may be only part of the solution, with further electrical repairs required to stabilise the system.

Addressing the root cause helps prevent ongoing damage to appliances and electrical equipment.

Surge Protection for Modern Homes and Appliances

Surge protection is especially important in modern homes due to the increased number of sensitive electronic devices connected to the electrical system. Many appliances are far more vulnerable to voltage fluctuations than older equipment.

Homes that benefit greatly from effective surge protection include those with:

Smart home systems and automation
Home offices and computer equipment
Solar power systems
EV chargers
High-value electronics and entertainment systems

Reliable surge protection helps extend appliance lifespan and reduce unexpected repair or replacement costs.

Timeframes and Disruption During Surge Protection Repair

Most surge protection repairs are completed efficiently once the issue is identified. Inspection and testing are often completed within an hour, and replacement is commonly carried out during the same visit, provided suitable devices are available.

Temporary power isolation is required for safety, but disruption is kept to a minimum and power is restored once testing confirms correct operation.
