What does fuse mean in electricity?
electrical safety device
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
Can I replace a 5A fuse with a 13A?
Re: Can I use a 13A fuse in a 5A plug ? No. You must use a 5A fuse. Using A 13A fuse is a fire risk.
Can I use a 5A fuse instead of a 10A?
Possibly yes. It is possible to short out a circuit by overdrawing more than 5 Amp by removing the 5 Amp fuse and putting in a 10 Amp fuse.
Where to place the fuse on a battery?
Recommended practice is to place the fuse near the positive terminal of the battery, so the whole circuit will be dead if the fuse blows. (Of course, if the positive terminal is considered Ground, place the fuse near the negative terminal.)
Do you connect the fuse to the positive or negative terminal?
Connect the fuse to the negative terminal of the battery since it’s where the actual flow of electrons originate which is opposite to the conventional flow of current from the positive terminal. Connect the fuse to the positive terminal. Connect two fuses, one at the positive and one at the negative battery terminals.
What happens when the first fuse catches fire?
It is important to note that the section of cable coming from the battery +ve terminal to the first fuse (or battery distribution box) is effectively an unprotected part of the circuit. If there is a short anywhere along this length then it is very likely to catch fire as the first fuse will not experience the excess current.
What happens if there is no fuse on a negative lead?
Without a fuse on that negative lead a 500 amp starter could be grounded with a 12 AWG wire to the battery. That wire would then become the fuse and burn up. Others mentioned the additional hazard of the antenna becoming part of the circuit on any kind of radio.
Can a 5A fuse handle 4.8 amps?
A 5A fuse can only handle 4A continuously, NOT 4.8. A 6A or 7.5A fuse will blow before wiring is compromised IF the wire is properly sized. A 10A fuse is pushing it, and with a 20A fuse, you may as well use a copper (pre-1982) penny. No matter how many amps a downstream device wants, the unit is maxed out @ 4.8.
Recommended practice is to place the fuse near the positive terminal of the battery, so the whole circuit will be dead if the fuse blows. (Of course, if the positive terminal is considered Ground, place the fuse near the negative terminal.)

Connect the fuse to the negative terminal of the battery since it’s where the actual flow of electrons originate which is opposite to the conventional flow of current from the positive terminal. Connect the fuse to the positive terminal. Connect two fuses, one at the positive and one at the negative battery terminals.
