What does a circuit breaker look like?
Circuit breakers look like a series of levers or switches, while fuses are round and are screwed into sockets. It’s good to know your circuits. Have a map of the panel that labels which circuit breaker or fuse controls which zone of the house. You can get this from the previous owner or the builder.
What happens when too many appliances are running at the same time?
If too many electric appliances are running at the same time, the load on the circuit increases. This can cause the wiring to breakdown and burn.

Contemporary cars utilize the customary ATC and ATO fuses that are known as blade-type fuses. The size and the numerous terminals make these fuses very distinct in nature.
Safety First
Replacement Fuses
Get to The Panel
- Go ahead and grab a headlamp or a handheld flashlight for when you get to the electrical panel. On the outside chance that you’ve never seen your electrical panel (your fuse box or breaker box), which houses the breaker switches or fuses that protect the various circuits feeding power to different rooms (or zones) in your home, now’s as good a time as any to familiarize yourself wit…
Blown-Fuse Confirmation
- If your home’s electrical panel features a circuit breaker, you want to look for a switch that’s moved from the “on” to “off” position, or one that looks like it’s somewhere in between. Clicking this single switch back into the “on” position should restore power to the circuit that you accidentally overloaded. However, if your home has a fuse box instead, you’ll want to look at all t…
Blown-Fuse Removal and Testing
- Not all fuses are designed identically. Some are easily snapped into (and out of) place with fingers, while others are manipulated more easily with small pliers, tweezers or screwdrivers. Once you’ve successfully removed the blown fuse and replaced it with the identically rated new fuse, you’re ready to test the circuit. Turn the power back on. If ...
Repeat Offenders
- If the same fuse repeatedly blows out, and you remain determined to avoid calling for professional help, other causes could include bad connections at wall plugs, new appliances or devices that use more power than the circuit can handle, a problem within an appliance itself, an overloaded outlet, or even loose wires somewhere inside the wall. Most of these you can trouble…
Root Causes
- Again, most blown fuses or tripped breakers are caused by overloading a single circuit, like when you have too many appliances running in your kitchen simultaneously, or when your teenager has plugged in one too many devices in a gadget-filled bedroom. However, if the same fuse keeps blowing (or the same breaker keeps tripping), and you keep replacing it without getting to the ro…
Preventing Another Blown Fuse
- Everyone knows what Ben Franklin supposedly said about an ounce of prevention being worth a pound of cure, so why not take steps to prevent future fuse and breaker hassles? One thing you can do is make sure you know precisely which outlets in your home apply to which circuits; in other words, get to know your zones so that you can make better plans for your electrical power …
Parting Thoughts
- Make sure your electrical panel is easily accessible and not blocked by furniture or anything else. Remember, many cars and electronic devices like stereos contain fuses to support various electrical functions. Identifying them and replacing them are no different from the careful steps you’d take when replacing fuses in your home’s electrical system. The same advice applies. Goo…
