Most people have probably had a blown fuse issue at some point in their lives. Despite the hassle that comes with it, blown fuses are fairly common. If you’re wondering what went wrong when you got a blown fuse at home, check out the list below. If necessary, contact a local electrician at US Electrical for a circuit breaker fuse repair.

Short Circuit – A type of electrical fault is a short circuit. Faults happen when an electric current deviates from its intended circuit due to a lack of resistance. As a result, the connection between the two conductors supplying electrical power to the circuit is compromised. Afterward, a short circuit occurs. Wires that are overloaded will cause damage. A short circuit may even result in damaging the plugged electrical appliance that caused it. Circuit breakers are typically used to stop short circuits, hence their name.

  • Overloaded Circuit – You should be able to identify the culprit in this case by looking for an overloaded outlet or an individual appliance. Consider a power strip with a plug in every outlet, especially if the devices plugged in require a high amount of energy.
  • Ground Fault – A ground fault is a type of short circuit in which the stray electrical current flows directly to the ground. Humans are, unfortunately, good conductors of electricity. Whenever a person comes into direct contact with a weak path to the ground, the risk of shock increases and it can become a safety hazard. As a result, GFCI (ground fault circuit interrupter) outlets are commonly found in kitchens and bathrooms.
  • Wrong Fuse Was Installed – Fuses are available in various shapes, sizes, and configurations. Many appear similar but serve very different purposes. If you or someone else installed the incorrect fuse in a fuse panel and no one was hurt, or property was damaged, it may still be a safety hazard for the building occupants.
  • Defective Electrical Outlets – Any defective wiring or connected fixtures run the risk of causing a power fault that trips a circuit (or blows a fuse). It is not the issue of a circuit breaker failing to function properly but because of the connected fixtures and equipment.
  • A Problem with the Breaker – If the breaker is simply tripped or if the switches on the panel are flipped, this is a normal occurrence. The circuit breakers are doing their job: cutting off the flow of electricity due to a surge or other problem. However, if it keeps tripping without any reason, monitor the breaker and call an electrician for assistance.
  • Your House Still Has a 100-Amp Service and Needs To Be Updated – Those “blown fuses” will most likely become more frequent, and you will need to keep resetting your circuit breakers. Our demand for electricity in the twenty-first century is much higher than in the twentieth. Unless you want to subject yourself and your family to strict electricity usage, it’s time for an update, which refers to a 200-amp system upgrade that will allow you to safely plug in and heat your electrical devices.

How Do You Solve Fuse Problems?

The most common problem at home is a blown fuse or a tripped circuit breaker. Such conditions can put you in a bind at any time of day. However, repairing a blown fuse can be done with the assistance of a local electrician.

Before you start any electrical repair, you must first understand why this issue is occurring. The fuses blow off depending on the maximum amp rating of the fuses and the amount of power load in your home. When too many electric appliances operate at the same time or when the electric load exceeds the maximum load, the wire fails. This actually works to keep your home and appliances in good condition. If you’re unsure what makes your fuse blow at home, consider reading the previous blog article to find the top x ways of a blown fuse.

  • Now that you know what causes a blown fuse, you must address the underlying cause first. Unplug any appliances that draw a lot of power, such as refrigerators and air conditioners. Also, if you purchased any new appliances, make sure to unplug them. Refer to the bullets below on the necessary steps to take for the specific fuse problem you have in your home.
  • Fix for a short circuit – Check that the faulty device is unplugged and the outlet is not damaged. First, run a circuit test. Then inspect the electrical panel for any damage. If you notice any damage, contact an electrician before proceeding. If there are none, return the breaker switch to its operational position. However, if it trips again, contact an electrician. 
  • Fix for an overloaded circuit – Reduce the amount of power that is being drawn from a single circuit. Find outlets on other circuits to plug into or, even better, unplug what you’re not using. You can also call the assistance of an electrician to add more outlets to your home.
  • Fix for a ground fault – This is essentially the same as the short-circuit repair. Ensure that all affected system components and electrical devices are tested. If the problem persists, contact an electrician.
  • Fix for the wrong fuse installed – Remove the fuse panel. Fuse panels haven’t been used in homes for decades, and their technology lacks the majority of the safety features found in modern circuit breakers.
  • Fix for defective electrical outlets – Repair the faulty outlet, and then have an electrical inspection performed on your home to identify other damaged outlets or potential problems in your electrical system. Knowing that one outlet had issues, an inspection should put your mind at ease. Any recommended repairs resulting from the inspection will make it even more convenient for you and your family.
  • Fix your defective breaker – Check for any signs of damage before resetting the breaker. If the breaker trips again, there may be an issue. Keep an eye on it, and contact an electrician if it continues to trip.
  • Upgrading your 100-amp breaker – The solution, in this case, is to contact your local electrician and discuss upgrading the service and replacing that very old fuse panel.
