The switchboard is an essential part of any electrical system, whether it’s in homes, businesses, or industrial settings. It distributes power throughout the building and ensures each circuit operates safely and efficiently. A failure or fire in the switchboard can pose serious risks. It can cause expensive damage and put the safety of people inside at risk.
In Sydney, where many older homes and buildings still rely on outdated electrical switchboards, understanding the risks and proper maintenance practices is vital. In this article, our local electricians offer tips to spot fire risks with switchboards. They also explain how to prevent potential switchboard fire hazards.
Why Switchboard Fires Are a Serious Concern
Switchboards are necessary for the functioning of any building, but they also come with inherent risks. Electrical fires can occur due to:
- Outdated wiring
- Overloaded circuits
- Rodent damage to wire insulation
- Poor maintenance
The National Fire Protection Association (NFPA) says electrical failures start more than 51,000 home fires in the U.S. every year. These fires cost $1.3 billion in damages, 470 deaths, and 1,400 injuries. Although Australia has different building standards, the risks remain similar, especially in older properties in Sydney.
Switchboards use high voltage, making fires involving them very dangerous. They are hard to put out because live wires are present.
Common Risk Factors for Switchboard Fires
From overloaded circuits to outdated components, several hazards can trigger a switchboard fire. Here’s what you need to know to stay ahead of the danger.
1. Overloaded Circuits
Overloading circuits is one of the most common problems caused by switchboard fires. Sometimes, we use many devices on a single circuit, leading to issues. High-wattage appliances, such as stoves, air conditioners, or fridges, draw substantial power. Too many devices are plugged into one circuit, which can exceed the circuit’s capacity. The causes of switchboard overheating and sparking a fire are as follows:
Prevention Tip: Ensure circuits aren’t overloaded and that your switchboard has proper load-balancing protections. Circuit breakers should be up-to-date and functional, cutting power when limits are exceeded.
2. Faulty or Ageing Wiring
Wiring that is frayed, improperly installed, or deteriorating can overheat and create sparks, which may lead to fire. This is particularly common in older Sydney homes with wiring that hasn’t been updated in decades.
Prevention Tip: Schedule a professional electrical inspection every 3–5 years. A licensed electrician can identify outdated wiring and ensure the safe operation of your electrical system.
3. Old or Damaged Switchboards
Most switchboards are designed to last 20–30 years, but over time, components can corrode, resulting in shorts, arcing, and fire hazards. Unfortunately, many switchboards in Sydney haven’t been upgraded for decades.
Prevention Tip: If your switchboard is more than 20 years old, consider upgrading it. Modern switchboards come with safety switches and enhanced circuit protection features.
4. Loose Connections and Poor Maintenance
Loose wiring can cause arcing. This is when electricity jumps between connections. Arcing produces heat, which can ignite nearby materials like insulation or dust.
Prevention Tip: Have a licensed electrician check and tighten all switchboard connections. Keep the area around the switchboard clean and dry to prevent dust or moisture buildup.
To resolve the electric fire, you must inspect the old or upgrade the new switchboard. Hire our electricians to get the best solution and quickly upgrade your commercial or residential switchboard.
Warning Signs of a Potential Switchboard Fire
It’s crucial to recognise early signs that your switchboard may be at risk. Look for:
- Frequent circuit breaker trips
- Buzzing or crackling noises
- Flickering or dimming lights
- Burning smells or scorch marks near the switchboard
- Visible sparks
- Smoke or discolouration
- Warm or hot switchboard surfaces
- Old-style ceramic fuses
- Breakers that won’t reset or are hot to the touch
These signs could indicate overheating, loose connections, or internal damage, which can result in fire if left unaddressed.
What to do: If you notice any of these symptoms, immediately turn off the main power supply and contact a licensed electrician. Avoid opening or attempting to repair the switchboard yourself as this could expose you to live electrical current or worsen the risk.
How to Prevent Switchboard Fires
Schedule Regular Electrical Inspections:
Routine inspections are your first line of defence. A licensed Sydney electrician can check for wear and tear, ensure tight connections, and evaluate load distribution across your switchboard.
Upgrade Outdated Switchboards:
Homes built before the 1990s often have ceramic fuses and no safety switches. These systems are less reliable than modern switchboards, which are equipped with Residual Current Devices (RCDs) that cut off power during a electrical fault.
Install Surge Protection:
Power surges, especially during storms, can damage circuits and potentially cause fires. Whole-home surge protectors help prevent excess voltage from entering your system.
Avoid Overloading Circuits:
Don’t plug too many high-powered appliances into a single circuit. Use power boards with built-in circuit breakers, and avoid daisy-chaining extension cords.
Keep the Switchboard Area Clean and Dry:
Moisture and dust can contribute to corrosion or even short-circuiting. Ensure the area around your switchboard is dry, well-ventilated, and free from debris.
