How to prevent blown fuses
Fuses are an essential safety feature in your home's electrical system, designed to protect your electrical circuits from damage by cutting off the electricity when there is an overload, a short circuit, or a faulty wire. However, repeatedly blown fuses can be frustrating and may indicate deeper electrical system issues. Here are some ways to prevent blown fuses:
Understand the causes of blown fuses
Blown fuses are commonly caused by overloading, which occurs when too many devices operate simultaneously on a single circuit, drawing more power than the wires can safely handle. This can cause the wires to overheat, leading to the fuse blowing as a safety measure to prevent fire hazards. Other causes include short circuits, faulty or outdated wiring, and physical damage to electrical outlets, switches, appliances, or the breaker box.
Reduce overload by using dedicated circuits
High-energy devices should have their own dedicated circuits to prevent overloading. For example, appliances such as microwaves, kettles, and hair dryers require a significant amount of power and can easily blow a fuse if the circuit is not designed to handle such loads. By giving these appliances their own dedicated circuit, you can prevent overloading and subsequent fuse issues.
Distribute appliances across different circuits
In addition to dedicated circuits for high-energy devices, it's important to distribute other device usage across different circuits. This helps to balance the electrical load more evenly and prevents any single circuit from being overwhelmed, reducing the risk of blown fuses.
Upgrade and maintain electrical wiring
Outdated or deteriorating wiring is less capable of handling modern electrical loads, especially in older homes. Worn-out wires, damaged insulation, and brittle connections can increase the risk of short circuits and ground faults, leading to blown fuses. Upgrading your electrical wiring and ensuring regular checks can help maintain electrical safety and prevent fuse issues.
Replace blown fuses correctly
When a fuse blows, it's important to replace it with a new one that matches the original's size, type, rating, and amperage. Using a higher-rated fuse can create a fire risk. Keep in mind that fuses are designed to be replaced, while circuit breakers can be reset. Always practice electrical safety when replacing fuses, and never attempt a repair if you're unsure or uncomfortable. It's better to call a qualified electrician for assistance.

Safety hazards and how to avoid them
Working with electricity is dangerous and can lead to electrical fires. If you are uncomfortable with the work, it is best to hire a professional electrician. Before starting work, ensure you pull all permits and shut off the power. If you are installing a GFCI, be careful as some areas of the breaker box still have power. Cut the wire jacket, but keep it on to prevent the bare ground from touching anything that is still live. Attach the ground wire first, then the neutral wire, before installing the new breaker and attaching the hot wire.
If you are running a 15-amp circuit, use 14/2 wire, and for a 20-amp circuit, use 12/2 wire. Try to find a path that does the least amount of damage to drywall and always follow local building codes. If you are installing a redundant power supply, ensure the UPS circuits are on different legs.
Dedicated circuits can help prevent safety hazards and electrical fires by ensuring appliances' electrical demands are met. Larger appliances need a bigger amp circuit, so a dedicated circuit ensures the appliance gets the current it needs without overloading other circuits. If you are unsure, an electrician can inspect your home and confirm if you have a dedicated circuit.
If you are installing a dedicated circuit, consider the overall complexity and the distance from the main electrical panel, as well as local labour costs. This will help you determine the final price and whether you need to hire an electrician.
