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 size is the wire? AWG 10, 600V is rated for 30 amps. Any AWG less than 6 would also be ok for a 30 amp circuit....
Sure, you can replace a 15 amp fuse with a 30 amp fuse, but it's not recommended. The 30 amp fuse has a higher current rating, which means it can allow more current to flow through the circuit than what it was designed for. This can pose a fire hazard and damage your electrical equipment. So, technically you can do it, but it's like putting a square peg in a round hole - it might fit, but it's not a good idea.
Use a 30 amp breaker.
Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
This is a unclear question, and not easy to answer. In your fuse panal, their will be a range of fuses, from 5 amp, up to 30 amp. On your fuse panal cover, should be a digram of your fuse panal, and which amp fuse goes into which slot.
Not a good thing to do! If you are blowing 10 amp fuses, you have a problem with that circuit. Putting a 30 amp fuse in its place can do more damage.
A 30 amp fuse wire typically has a diameter of around 0.08 inches (2 millimeters).
A 30 amp fuse is required.
The blower motor could stop working if it blew the 20 amp fuse. That's probably the worst that would happen. You should replace it with a 30 amp fuse, if that is what's called for in your manual.
The 1965 Chevrolet Impala SS fuse box requires a 20 amp fuse for the taillights. A 30 amp fuse can be used when a 20 amp fuse is not available.
circuit breaker fuse
It should work with a 20 amp, just not as long. Wipers use a fair amount of current so the factory puts a 30 amp in. Perhaps that particular 20 amp is bad or it blew as soon as you turned the wipers on.
What is the 40 amp RSI fuse in a Lexus rx 300 fuse box
The standard color coding for fuses in American wire is as follows: 15-amp fuse: blue 20-amp fuse: yellow 30-amp fuse: green
It is not recommended to replace a 30 amp fuse with a 25 amp fuse in a central AC unit. The fuse should match the specified amperage requirements to prevent damage or overheating of the unit. Using a lower amp fuse could potentially lead to electrical issues or failure of the AC unit.
If a 30 amp blows you have a short somewhere. Depends for which circuit, you will have to track it from the unit back to the fuse.
