Electrical fires are often described as smelling fishy, which can be easy to mistake for a cooking odour or rotting food. However, if you're not cooking or handling fish, the smell could indicate a serious electrical problem that needs immediate attention. The fishy odour is caused by overheating electrical components, such as wires, outlets, and circuit breakers, which emit a fishy smell due to the breakdown of heat-resistant chemicals and plastics used in their insulation. This smell is an early warning sign of potential electrical fires, and it's crucial to act quickly to prevent a dangerous situation.

What You'll Learn
Overheating electrical components
A fishy smell in your home or business is often an indicator of an electrical fire that has started or is likely to start soon. Electrical fires can be particularly devastating and hard to put out. Therefore, it is important to act quickly and not ignore the smell.
Electrical wires are protected by insulation, which is usually a plastic-based coating that is not conductive. This insulation also contains heat-resistant chemicals to make things extra safe. However, if the wires overheat, the insulation can begin to melt and release a fishy smell. This can be caused by overloaded circuits, undersized wiring, or electrical surges, among other things.
If you notice a fishy smell, it is important to shut off the power and locate the source of the smell. Do not try to find the source of the smell on your own, as this could be dangerous. Instead, contact a licensed electrician to inspect and repair the issue. They will be able to pinpoint the problem quickly and safely. In some cases, you may also need to call 911 or your local fire service.
To prevent electrical fires, it is important to have annual electrical safety inspections and stay on top of any necessary upgrades to your electrical system. This includes ensuring that your breaker box is rated for the load you are putting on it and that your wiring is up to date.

Electrical surges
A fishy smell in your home could indicate an electrical fire hazard. Electrical fires typically occur when there's an issue with electrical wiring in a building or a faulty or damaged appliance.
To prevent electrical fires caused by surges, you can use surge protectors, which shield devices from unexpected power surges from outlets. It is also important to unplug devices when not in use to avoid overheating.
If you notice any signs of your electrical outlets, light fixtures, or appliances overheating or drawing excessive current, you should call an electrician and emergency services.

Outdated electrical wiring
A fishy smell in your home could indicate that you have outdated electrical wiring. Old wiring can degrade and break down, causing it to overheat and start an electrical fire.
Electrical wires are coated in insulation, usually a plastic-based sleeve, to protect them from the outside world. This insulation is not conductive, so electricity is safely contained within the wire. Insulation also contains heat-resistant chemicals to provide extra protection from electrical fires, which are particularly difficult to extinguish. However, if the wires are overheating, this is a sign that there is a problem.
If your wiring is overheating, the insulation will begin to melt and release a fishy smell. This is caused by the combination of melting plastic and chemicals in the insulation. If the problem is not addressed, the insulation will continue to burn until it is used up, leaving exposed electrical wires in your home. This can lead to electrical fires, which can develop quickly and cause significant damage.
If you notice a fishy smell, it is important to act quickly. Shut off the power and locate the source of the smell. Do not try to find the source of the smell yourself, as this can be dangerous. Instead, contact a licensed electrician to conduct an electrical inspection and make any necessary repairs.
To prevent electrical fires, it is important to keep your electrical wiring up to date and ensure that your electrical system is safe. This may involve upgrading your wiring and breaker box if you have installed new appliances. Regular electrical inspections can also help identify potential hazards and ensure the safety of your home and family.

Burning chemicals or insulation
A fishy smell is often an early indicator of a serious electrical problem that could lead to a fire. This smell is caused by the burning of wiring insulation and the heat-resistant chemicals used in outlets, circuit breakers, and wiring insulation.
When electrical components such as wires, outlets, and breakers overheat, the chemicals they are made of release a peculiar odour that smells like fish. This can occur due to overloaded circuits, undersized wiring, or faulty components.
As wiring insulation begins to melt, it emits a fishy odour, which can be misinterpreted as a smell other than burning plastic or rubber. This is often accompanied by a buzzing sound from the electrical panel, indicating that the wiring insulation is burning or the circuit breaker has failed and is overheating.
It is crucial to locate the exact source of the problem and address it promptly. Ignoring or delaying repairs can lead to dangerous situations as unresolved electrical issues significantly increase the risk of fires. Turning off the power and seeking professional assistance is the best course of action to ensure the safety and reliability of your electrical system.
If you suspect an electrical fire, it is essential to contact emergency authorities or a licensed electrician immediately. Knowing what an electrical fire smells like can help you act quickly to prevent a fire from spreading.

Undersized wiring
The fishy smell is caused by the heat-resistant chemicals used in wiring insulation breaking down and releasing gases that have a fishy odour. This smell can be an early warning sign of a potential electrical fire, as it indicates that the wiring is overheating. It is important to address this issue promptly, as neglecting it can lead to a dangerous situation.
If you notice a fishy smell, it is important to take action immediately. First, turn off the power and locate the source of the smell. If you are unable to identify the source, contact a licensed electrician to perform an inspection and make any necessary repairs. It is recommended to have an electrical maintenance plan or to conduct regular electrical inspections to prevent potential fire hazards and ensure the safety of your home or business.
In some cases, the fishy smell may be due to other factors such as rotting food, leaking sewer gases, or dead animals. However, if there is no apparent cause for the smell and it persists, it is likely an electrical issue. Dimming and flickering lights, buzzing noises, and sparks from outlets can also indicate underlying electrical problems.
To prevent electrical fires due to undersized wiring, it is important to ensure that the wiring is properly sized for the electrical load. This may involve consulting with a professional electrician to assess the electrical needs and ensure that the wiring is adequate. Upgrading to higher-gauge wires or installing additional circuits can help prevent overheating and reduce the risk of electrical fires.
