Signs Your Switchboard Needs Attention

Your switchboard is the heart of your electrical system, responsible for safely distributing power and ensuring seamless operation throughout your space. However, like any crucial component, it can experience wear and tear over time. To prevent potential hazards and disruptions, it’s essential to recognise the signs that your switchboard may be in need of attention.

Are your lights flickering or dimming frequently? This could indicate an overload or a loose connection within your switchboard. Additionally, if your circuit breakers are tripping often, it might suggest an imbalance in your electrical load or a faulty component in your switchboard.


A distinct burning smell near your switchboard is another red flag. It could point to overheating or damaged control wiring that requires immediate inspection. Unusual buzzing or humming sounds from your switchboard could signify loose wires or deteriorating components.

If your switchboard is outdated and lacks modern safety features, it’s time to consider an upgrade. Older electrical switchboards might need to meet the demands of today’s electrical appliances. Visual signs of corrosion or rust on your switchboard panels should not be ignored.

These could lead to poor connections and compromised performance. Frequent power surges or fluctuations can stress your switchboard and other connected devices, potentially causing long-term damage. Adding new appliances or residual current devices may strain an undersized switchboard, leading to inefficiencies and potential hazards. If a tripped circuit breaker doesn’t reset, it could indicate a deeper switchboard issue requiring professional attention.

Touching your switchboard and noticing excessive heat clearly indicates an underlying problem. Heat can lead to component failure and even the risk of electrical fires. It’s crucial to pay attention to these warning signs. If you observe any of these indicators, it’s time to reach out to our expert technicians.

How To Maintain Your Electrical Switchboard

Maintaining your electrical switchboard is essential for your electrical system’s safety and proper functioning. Here are some steps to help you maintain your electrical switchboard:


1. Undertake Regular Inspection

Schedule routine switchboard inspections to identify any signs of wear, damage, or corrosion, along with checks such as insulation resistance testing, which can only be performed by licensed electricians. Check for loose connections, burnt components, and any unusual odours. It’s crucial to catch and address issues early to prevent potential hazards.

2. Keep Your Switchboard Clean

Dust, dirt, and debris can accumulate over time, potentially causing switchboard malfunction, short circuits, or even increasing the risk of electrical fires. Use a soft brush or compressed air gently to clean the switchboard gently. Make sure to turn off the power before cleaning and avoid using water or wet clothes.

3. Ensure All Connections Are Tightened

Loose connections can lead to overheating and electrical equipment failure. Carefully inspect and tighten all terminal connections, including wires, weather seals, safety switches, fuses, circuit breakers, and other components. Ensure they are secure but not over-tightened, which could damage the connections.

4. Replace Any Worn Components

If you notice any damaged or worn-out components, such as frayed wires, corroded terminals, or burnt fuses, replace them immediately. Using damaged components can compromise the safety of your electrical system.

5. Check for Overloading

Ensure that your switchboard is not overloaded with too many appliances or devices. Overloading can lead to overheating and trip circuit breakers. If you need to add more circuits, consider consulting a licensed electrician.

6. Make Use Of Proper Labelling

Properly label all circuit breakers or fuses to identify and control each circuit easily. This makes it easier to shut off electrical power to specific areas during regular maintenance or emergencies.

7. Ensure Correct Ventilation

Ensure that the switchboard area is well-ventilated to prevent heat build-up. Excessive heat can cause components to fail prematurely.

8. Keep Clear Access

Do not store items in front of or around the switchboard that could obstruct access during an emergency or perform regular maintenance. This will ensure you can easily reach and work on the switchboard when needed.

7. Schedule Professional Inspections

Periodically, hire a licensed electrician to inspect your switchboard thoroughly. They can identify potential minor issues that may need to be apparent to an untrained eye and provide expert recommendations from licensed electricians or technicians.

8. Follow All Safety Precautions

Prioritise safety while working on or near your switchboard. Always turn off the main power supply before performing any routine maintenance tasks. If you need clarification on any aspect of switchboard maintenance, it’s best to consult a qualified electrician.

When To Call a Professional Electrician For Switchboard Maintenance

While a proactive approach to switchboard maintenance is commendable, there are instances where the expertise of a professional electrician becomes not just beneficial but crucial. Recognising these pivotal moments ensures not only the optimal performance of your electrical system but also the safety of your surroundings.

If you encounter recurring issues that persist despite your best efforts, it’s time to seek a professional’s insight. Whether it’s tripped circuit breakers, flickering lights, or mysterious power fluctuations, a qualified electrician possesses the expertise to diagnose the root cause and implement lasting solutions to keep your property in good working condition.

Any signs of physical damage or deterioration, such as scorch marks, burning odours, or visible rust, warrant immediate professional attention. These red flags can hint at underlying issues that pose serious safety risks, and attempting to address them without proper knowledge could exacerbate the situation.


Suppose you’re planning significant changes or additions to your electrical setup. Be it new equipment installations, renovations, or a boost in electrical power demand – consulting an electrician is a prudent step. They can ensure your switchboard is equipped to handle the increased load and that all modifications adhere to safety standards and the manufacturer’s instructions.

On top of these everyday electrical matters, the intricacies can be daunting when dealing with complex switchboard systems or electrical devices, particularly in industrial or commercial settings. A professional electrician brings in-depth knowledge of these setups, minimising the chances of oversight or error during proper maintenance.
