A fuse with a higher than rated for a electrical circuit is used to handle spikes in the electricity delivered. Lets take a normal household wall socket. They are said rated at 120 Volt . They are in fact 115 V to 125 V a/c electricity @ 15 Amps.
Current i.e.rate of flow of charge when stops flowing in a circuit then fuse does not blows out. The only work of fuse is to blow away when the current starts flowing greater in magnitude than the rated current value.
Yes you can do that as long as it will fit in the fuseholder. It is acceptable to replace a lower Voltage Rated fuse with a higher but NEVER replace a higher with a lower. There are several things to consider when replacing a fuse: 1) The minimum voltage rating of the fuse is equal to or higher than the voltage of the circuit you are placing it in 2) The Amperage rating of the fuse does not exceed the capacity of the circuit you are trying to protect. Always replace a fuse with one that has the same amperage rating. 3) The interrupting rating of the fuse is sufficent for the capacity of the circuit supplying the fuse. If replacing a fuse always use one with an interrupting capacity equal to or greater than the fuse you are replacing.
Yes, 20 amp fuses are available in many different sizes and types.If what you meant is "Can you upgrade from a 15A to a 20A fuse?" then, for more information, see the answers to the Related questions shown below.
A fuse is a piece of wire that has a lower current rating than the rest of the circuit. When power is applied to a wire, it heats up (which is why electrical items get hot with use). The fuse wire melts at a lower temperature than the rest of the circuit - meaning that it breaks before the device is damaged by high current.
The circuit or device that the fuse was meant to protect would not be protected if a fuse with a higher rating were to be used. This could result in the circuit or device being destroyed by a higher than normal current flow in a short circuit fault condition.
The fuse is supposed to be the weakest link in the circuit. The circuit is rated to handle a specific load current. The wire and insulation rating of the circuit is governed by this specific load. If this load malfunctions and the load current becomes higher that what is specified, the fuse is there to break the circuit. A fuse of a higher rating than what is called for will allow a higher current to flow through the circuit which could cause the insulation on the wire to melt, the wire to burn open or components in the circuit to become unusable. Never over fuse an electrical circuit with a larger amp rated fuse.
The way current (series) fuses are designed and used, they are meant to overheat and blow and cause an open circuit if the current flow through these goes above the rated value. The resistance value typically is slightly higher than the wiring and adds marginal value of series resistance to the overall circuitry. The material characteristics of fuse ensure that at regular nominal current flow the fuse does not overheat, but when larger than expected current flows it overheats, melts (or gives very high resistance/open in a resettable fuse)and causes circuit to open.

No. The 240V lamp will pop the circuit or fuse because the draw is higher than the supply.
A fuse blows when the current draw of the circuit is greater than the capacity of the fuse.
True. The voltage rating of a fuse must be greater than the circuit voltage.
A fuse in its simplest form - is simply a short piece of wire that is weaker than the circuit it is protecting. When the current flowing through the circuit exceeds the fuse rating, the fuse wire melts - breaking the circuit.
Yes a 10 amp fuse can be used to protect a 240 volt circuit. The amperage rating of a fuse is based on the given amperage load of the circuit. The voltage rating on a fuse must match or be higher than the voltage that is applied to the fuse. In other words you can not use a 240 volt fuse on a 277, 347, 480 or 600 volt circuit but it can be used on a 120 volt, Manufactures of switching equipment today make it impossible to interchange different voltage fuses to be installed in higher voltage switches.
A circuit that keeps blowing a fuse, is caused by a Short in that circuit, loose connections causing arching, overloaded circuit, or a fuse that is too small for the circuit load. Do not install a fuse bigger than the circuit was designed to handle. Someone may have install too small a fuse. Check fuse list and see if the proper fuse is installed.
Fuse is a device that acts as a traffic controller in the electric circuit, it means it breaks the circuit when the power of current is more than what it it needed and prevents the possible damages ...
You can, but it is would increase the danger of a circuit overload. And that could cause damage to the equipment or result in a fire.
