What if house fuses blowing?

If a fuse in your home keeps blowing it can be caused by several things. Most often it is because that circuit is being overloaded. There is simply too many things pulling power on that circuit. It can also be caused by a short in the wiring somewhere. Can also be an appliance is defective. Can also be someone has installed a fuse that is too small for the circuit. Whatever you do, do not install a larger fuse than the circuit calls for to prevent it from blowing. The fuse is there to protect the wiring from overheating and catching on fire.


Can a 30 amp fuse replace a 40 amp fuse on a lawnmower?

You can replace a higher rating fuse with a lower rating provided it works with the device without constantly blowing. So try the 30 amp fuse in your lawnmower and if it doesn't blow and the mower works okay, you are fine. If it blows you will have to go back to 40.


What does the interrupting capacity of a fuse indicate?

The interruption capacity of a fuse is the ability of a fuse to stop the current flow on a short circuit condition. On high rupture capacity (HRC) fuses the fuse cartridge has silica sand surrounding the fuse link. When the link blows under a high current so much heat is generated that the silica sand actually turns to glass to extinguish the arc. A dual element fuse is used on motor starting circuits. Their construction inside with two current flow paths allow the high current of a motor start for a short interval of time without blowing.


How do you find out why a fuse keeps blowing out?

First check what's actually serviced by that fuse, maybe you've added something that wasn't there from the beginning, pushing the draw over the allowable limit. If that still looks OK, start by disconnecting the stuff hooked up to that fuse one by one, see if that can narrow things down. If that doesn't show anything, then you have to start inspecting the wiring itself for damages.


How much can you load on a 15 amp fuse?

Fuses can last for 10 years or more because fuses don't really wear out unless perhaps they are run continuously right at the edge of blowing. The constant heat of near-high amperage (which is what blows the fuse anyway) will eventually cause it to trip at a lower amperage than when it was new. Water will corrode a fuse and cause it to blow and low voltage on a circuit feeding a motor will drive the amps up, causing a fuse to blow when it would have been ok at normal voltage (12.6-13.6 dcv). And corrosion on the fuse blades inhibits voltage.
