What You'll Learn
Call an electrician for a safety inspection
Electrical fires can be extremely dangerous and sometimes even deadly. They can cause severe damage to property and pose a threat to the safety of those inside the house. Hence, it is always better to stay alert and take preventative measures to stop them from happening. Calling an electrician for a safety inspection can help deal with any issue before it becomes a serious hazard.
A licensed electrician can help ensure that any electrical modifications meet existing codes and standards. They can also replace outdated or malfunctioning fuses and circuit breakers and instruct you on their proper usage. If your home was built between 1965 and 1973, consider having the aluminum wiring inspected. If a complete household rewiring is not an option, copper connector "pigtails" can help mitigate some of the dangers and problems of aluminum wiring.
Electricians can also inspect or replace faulty wiring that could cause an electrical fire. Burning smells from outlets, sizzling sounds from walls or outlets, and frequently blowing fuses or tripping circuits are all signs of potential electrical problems that should not be ignored. If you experience such issues, it is important to call an electrician to investigate and resolve the problem.
In addition, an electrician can install additional outlets to prevent overloading, as well as ground fault circuit interrupters (GFCIs) and arc-fault circuit interrupters (AFCIs) for added safety. They can also advise on other safety measures, such as using the right light bulb wattage, positioning lamps away from combustible materials, and avoiding the use of extension cords in place of outlets.
By calling an electrician for a safety inspection, you can identify and address potential electrical fire hazards, ensuring the safety of your home and family.

Burning smells from outlets
A burning smell from electrical outlets is a serious issue and should not be ignored. It could indicate a potential electrical fire already in progress. If you experience such a situation, act quickly and follow these steps:
Locate the source of the burning smell
Use your nose to find the source of the smell. If the odour gets stronger as you approach an outlet, it is likely coming from that outlet.
Unplug electrical devices and turn off the circuit breaker
If the burning smell is coming from an outlet, unplug any devices connected to it. Then, locate your breaker box and turn off the circuit breaker that controls the affected outlet. This will help prevent further damage and reduce the risk of electrical fire.
Call for professional help
Once you have addressed the immediate situation, it is important to call a licensed electrician to inspect your electrical system and identify the root cause of the burning smell. Electrical fires can be dangerous, and it is always better to take preventative measures to stop them from happening. A professional electrician can provide a comprehensive inspection and address any issues safely and effectively.
Common causes of burning smells from outlets
There are several possible reasons why an outlet may emit a burning smell, including overloaded circuits, loose connections, faulty wiring, or malfunctioning electrical appliances. Overloaded circuits can cause the wiring and components in the outlet box to overheat, leading to a burning smell and potentially an electrical fire. Loose connections and faulty wiring can also create resistance and heat, resulting in a burning odour and an increased risk of fire.
It is important to take prompt action and not ignore a burning smell from an outlet, as it could indicate a serious problem with your electrical system. By following the steps outlined above, you can help ensure your safety and prevent further issues.

Sizzling sounds from walls/outlets
Sizzling sounds from your walls or outlets are a cause for concern and should not be ignored. While electrical systems are expected to be silent, these sounds could indicate a serious underlying issue.
Electricity flowing through wires can make a sizzling sound, akin to frying bacon. Hearing these sounds from your walls or outlets could indicate a problem, especially if the sound persists or is coupled with burning smells. These sizzling sounds could be a result of an overloaded circuit, which, if left unchecked, can lead to electrical emergencies.
If you hear these sizzling sounds, it is recommended to switch off and unplug any appliances or electronics in the area. This is because the sizzling could be a result of series arc faults, which create a significant amount of heat and may cause things to burn. While these arc faults may not trip a breaker, they can lead to house fires.
If you encounter these sounds, it is best to contact a professional electrician. They can identify the source of the issue and provide safe and effective solutions. Electricians can inspect wiring and electrical fixtures to ensure your safety and prevent potential electrical fires.

Circuit breakers keep tripping
A circuit breaker is a switching device that controls and protects your electrical power system and all the electric gadgets connected to it. It cuts off the flow of electricity to your home to prevent a circuit from overheating and causing an electrical fire. Therefore, a tripped breaker is a sign that something has gone wrong, and depending on when it happens, it can cause a huge interruption in your day. While it can certainly be an inconvenience, it’s an important safety feature that protects you and your home from a fire.
There are several reasons why your breaker keeps tripping. One of the most common reasons is an overloaded circuit, which occurs when the electrical load exceeds your electrical system’s rating. Your breaker switch will trip whenever it detects an electrical current greater than the circuit system’s rated value. Common signs of an overloaded circuit are warm receptacles, discoloration on switches, dimming lights, and burning smells. To address this problem, you can redistribute your appliances and electrical gadgets and keep them off the same circuits. Turning off some of your devices can also minimize the electrical load on your circuit breaker.
Another reason for a tripping breaker could be a short circuit. This happens when two wires—a hot wire and a neutral wire—touch, causing the wires to heat up suddenly. Depending on where the short circuit has occurred, you may be able to smell it. If you suddenly lose power and can notice a burning smell, you likely have a short circuit. If the short circuit is behind your walls, you will need to call a qualified electrician to fix it.
Ground faults can also cause a breaker to keep tripping. A ground fault occurs when the electrical current takes an unintentional path to the ground, such as when the live wire comes into contact with the ground wire or the outer casing of an appliance. Like short circuits, ground faults reduce the resistance within the conductor, leading to uncontrolled current flow.
If your breaker keeps tripping, it is important to take this warning sign seriously and call an electrician to investigate. They can help identify the root of the problem and recommend solutions, such as dedicated circuits or additional circuit installations and upgrades to ensure the right supply is being provided in your home.

Sparks or flames
If you see sparks or flames in your house, it is important to act quickly as electrical fires can spread rapidly. Your priority should be to ensure your safety and that of anyone else in the house. Get everyone out of the house and call the fire department or local authorities immediately. Do not try to tackle the fire yourself.
Once everyone is out of the house, you should wait for the emergency services to arrive. If you feel comfortable doing so, you can try to identify the source of the sparks or flames. This could be machinery, equipment, exposed wiring, or electrical panels. If you can identify the source, turn off the power to the affected area to prevent further electrical arcing and minimise the risk of fire or electric shock.
If you cannot identify the source of the sparks or flames, or if you do not feel comfortable attempting to do so, you should still turn off the power to the entire house if possible. If the source of the issue is not inside the house, it may be a wire connected to the outside of your house. In this case, you should contact your electric company and inform them of the issue. They will likely send someone to fix the problem.
In any case, it is important to call an electrician to assess the damage and make any necessary repairs. Electrical sparking can be a sign of a more significant electrical hazard or fire risk, so it is important to take action and not ignore the issue. Regular electrical inspections can help to prevent issues from occurring, so it is recommended to have your home's electrical system inspected by a qualified electrician.
