Protecting Your Home Against Power Surges

Power surges are one of the most common causes of electrical damage in Brisbane homes. From severe storms and lightning to heat-related grid overloads and transformer faults, voltage spikes can enter your home without warning and quietly damage appliances, solar systems, and wiring.

At Precision Electrical & Air, we install professional surge protection designed to protect your home at the switchboard, not just at the power point.

What Causes Power Surges in Brisbane?

Brisbane’s electrical network is exposed to a wide range of surge events, including:

  • Electrical storms and nearby lightning strikes
  • Extreme summer heat causing grid overloads and brownouts
  • Power being restored after outages
  • Transformer failures or explosions
  • Vehicle accidents damaging power poles or substations
  • Voltage instability in areas with high solar penetration

Even small or repeated surges can shorten the lifespan of air conditioners, televisions, computers, and solar inverters over time.

Why Plug-In Power Boards Aren’t Enough

Many homes rely on plug-in surge-protected power boards. While these offer limited protection for individual devices, they do not protect your entire electrical system.

Surges often enter through:

  • The main power supply
  • Solar inverter connections
  • Sub-boards or long cable runs

Without switchboard-level protection, surge energy can still travel through your wiring and damage fixed appliances and safety systems.

From minor repairs to new installations and full system upgrades, Precision Electrical & Air has you covered.

Professional Surge Protection at the Switchboard

We install surge protection devices (SPDs) directly into your switchboard, where they can respond instantly to voltage spikes.

When a surge occurs, the surge arrestor diverts excess voltage safely to earth before it reaches your circuits. This happens in microseconds, far faster than circuit breakers or safety switches can respond.

Homes with solar need layered protection:

  • One surge arrestor protecting the incoming grid supply
  • A separate surge arrestor protecting the solar inverter supply

Surges don’t just come from outside the home — solar inverters can also introduce voltage spikes during switching, shutdowns, or grid disturbances. Installing protection on both sides ensures your home and solar equipment are properly shielded.

What Surge Protection Helps Protect

A properly installed surge protection system helps protect:

  • Air conditioning systems
  • Televisions and home entertainment
  • Solar inverters and batteries
  • Computers and networking equipment
  • Kitchen appliances and refrigeration
  • Safety switches and smart home systems

It also reduces nuisance tripping and helps maintain stable power throughout the home.

Do Surge Arrestors Need Maintenance?

Yes. Surge arrestors are sacrificial devices: they absorb damage so your equipment doesn’t.

After major storms or surge events, they may no longer provide protection. Many devices include a visual indicator to show when replacement is required.

We recommend:

  • Inspection after severe storms
  • Checks during switchboard servicing or electrical safety inspections
  • Replacement when indicators show the device has been exhausted

I cannot speak too highly of James. I have a very high opinion of him both as a person and professionally. He had done some electrical work on our home prior to the flood. During last year's February flood he really shone as a person. He promised as soon as power was restored to our street we would be connected. It was a Saturday afternoon and he was as good as his word. In no small part we have him to thank for being able to return home within a week, after being flooded with over a meter of water. I will always be grateful and indebted to James for being there for me during this difficult time. Today James serviced 4 air conditioners , 3 of which he installed. As expected he did a wonderful job and a pleasure to work with. I confidently and unconditionally recommend James and his Company.

I had a really good experience with James from Precision Electrical & Air. He did a great job with the repairs at my home, and I was very happy with the quality of his work. He was also really friendly, polite, and easy to deal with. It’s always nice to find someone who is not only good at their job but also genuinely pleasant to work with. I would definitely recommend James and Precision Electrical & Air!

TL;DR Precision electrical & air are excellent, and I have no hesitation to recommend them and to continue calling them up to perform future electrical work. _______________________________________ (essentially all of my jobs with precision has been aircon related, so I will be talking from that point of view) I have had Precision perform a few aircon jobs at my home over the past year; new aircon installs, aircon replacements and some smaller electrical work (new outlets + vent fans) and they have been excellent every single time. I have zero hesitation to recommend them, and have done so to colleagues and friends whenever the discussion of electrical work comes up. James has shown a high level of knowledge during the on-site quoting process, taking the time to explain what the work may look like, ideal options as well as potential alternate options for installation, placement, unit types and what the requirements will be for a proper installation to meet warranty requirements. He does this all with the requirements of the customer in mind, first and foremost achieving that requirement first and then presenting aforementioned options. He is also very responsive and detailed in answering queries I have asked to clarify some points before accepting quotes. Joel & Elliott have been the chaps that have come around to perform the numerous jobs, and they have been very, very considerate, patient and are clearly hard workers who take pride in their work. I usually WFH when the job is being performed, and the boys always kindly inform me when they need some assistance getting access to areas, when power needs to be turned off (saved me from suddenly dropping out of meetings) and when they run into some small bumps. All these "bumps" so far were immediately rectified and are very minor non-issues. The boys are also very accommodating, taking the little bit of extra time to clean up & help reset furniture (when able), explain thoroughly how the job went, anything to keep in mind with the new installs (AC drain pump), scoot over their vehicles when the wife needed to pop out for her work amongst many other things that minimized disruption to the household on the day. Pricing is quite reasonable, with the workmanship in mind I would say pricing is excellent. I look forward to having Precision perform further work on my home. (Roy)

Fantastic experience with Precision Electrical & Air. James carried out a thorough inspection and provided a prompt, very fair quote. The new downlights have completely transformed our space.

Great experience with the guys from Precision Electrical - they were prompt, professional and efficient - also took the time to explain what was going on and their recommendations to address the issue. Elliott and the other guy (cannot recall his name, I'm sorry) were great!

Surge Protection Questions, Answered

01Why are power surges common in Brisbane homes and businesses?

Power surges are common in Brisbane due to frequent electrical storms, extreme summer heat, grid overloads, and power being restored after outages. Transformer faults and car accidents damaging power poles can also send sudden voltage spikes through the local network.

02Can Brisbane storms damage appliances even if the power doesn’t go out?

Yes. Many surge events happen without a full blackout. A nearby lightning strike or grid disturbance can send a voltage spike through your wiring in milliseconds, damaging air conditioners, TVs, solar inverters, and electronics without cutting power completely.

03Does surge protection help with brownouts and heat-related power issues?

Yes. During Brisbane heatwaves, high demand on the grid can cause unstable voltage and brownouts. Surge protection devices help limit voltage fluctuations and protect sensitive equipment from damage caused by repeated power instability.

04Is surge protection recommended for homes with solar in Brisbane?

Yes. Homes with solar systems in Brisbane are at higher risk of surge damage because surges can enter from both the grid and the solar inverter. Installing surge protection on both the mains supply and the solar side helps protect inverters, batteries, and connected appliances.

05Do surge protection devices need replacing after Brisbane storms?

They can. Surge protection devices absorb damage to protect your electrical system. After major storms or surge events, they may no longer provide protection and should be checked by an electrician. Many devices include indicators showing when replacement is required.
