Can I put a 30A fuse in a 20A?
The fuse is there for safety. If you use a 30A fuse in place of a 20A, you increase the likelihood of fire and damage if there is an electrical fault in the wiring or device powered by that voltage. USE THE CORRECT FUSE.
Is a 20 amp plug the same as a 30 amp?
A 20 ampere socket is only rated for a maximum of 20 amperes so can not be used to power a 30 ampere plug.
Can I use a 30 amp fuse instead of 25 in car?
Never ever. A 25 amp breaker is probably protecting 12 gauge wire. A 30A breaker protects 10 gauge wire. If you have 10 gauge wire everywhere in your circuit, and you have verified this, then you can install a 30A breaker.
What happens if you don’t replace 30 Amp Fuse?
If the wiring is not rated for at least 30 amps and you have a 30 amp fuse/breaker the wires can overheat and cause a fire, usually the failure will be at a splice or some type of connection so without knowing any better leave the 20 Quite possibly nothing. For years and years.
Why 20 amps on a 30 amp circuit?
You then sometimes get something known as fire. 20 amps is chosen because that is what the branch that circuit is designed to handle safely. The wire, the outlets, all of it was chosen to NOT get too hot with that much current flowing through it. But put 30 through it?
What size fuse do I need for a 20 amp motor?
You then protect this all with a fuse that will blow if the current draw exceeds the figure expected during normal use. A 20 Amp fuse should easily cope with the current demands of the motor but will blow if exceeds it by too much. You then replace this 20A fuse with a 30A.
Why does a fuse blow at a certain current?
It is really not relevant that the fuse blow at certain current, it’s about how fast it can blow without consequences. The fusing time is inverse related to overload current, and for the same overload a 30 A fuse is slower than a 20 A, for same type.
