How transformer get burn?
Current overload from whatever circuit draws current from the transformer? Proper fusing of its supply might protect a transformer from this cause. Or it could have developed a shorted turn fault because the insulation on a winding got old and perished? Or maybe the transformer got damaged if the appliance it is mounted in was dropped?
How can copper be removed from an electric motor?
Take it apart and burn the insulation out, if you can, in a pile of brush. Or you could also take a torch to it and see if that gets the insulation out. If you use flame to melt the copper, beware of toxic fumes from burning rubber and plastic insulation.
What Precautions must be taken when using fuses?
the fuse protection feature should be adapted to overload characteristics of protected objects, considering the possible short-circuit current, choose corresponding fuse breaking capacity;2, fuse to be adapted to line voltage level, the rated voltage of rated current of the fuse is greater than or equal to the rated current melt;3, line fuse melts at all levels in the rated current to the corresponding coordination, keeping the level of the melt must be greater than the rated current level of the melt under the rated electric current;4, fuse melts to use combination according to the requirement of the melt, not allowed to increase the melt or other conductor instead of the melt.
What happens to an electric motor is it over heats?
If a fuse fails to blow or a cut-off doesn't come into play, the insulation on the wires will melt and cause a short circuit.
How long for a cable to heat up at maximum current rating?
It depends on the surround material, temperature, type of cable, and what you mean by "maximum current rating". Typically a maximum load current rating will be specified, such as 15A; this means you can push 15A through that cable nonstop without damaging it (it won't overheat). You might have a short time rating as well, such as a 4 hour rating, where the cable can handle runing 22A for 4 hours if the surrounding temperature is kept to some value, though this may slightly degrade the insulation. There's also a fusing current rating for many cables. At this current, the cable will eventually melt (like a fuse).

This melts if the current gets to high?
The conductor's insulation can melt if the current gets higher than the ampacity of the conductor.
How do you calculate the current required to melt 14 gauge wire insulation?
To calculate the current required to melt 14 gauge wire insulation, you need to know the specific heat capacity and melting point of the insulation material. You then use the formula Q = mcΔT to calculate the heat energy required to melt the insulation, where Q is the heat energy, m is the mass of the insulation, c is the specific heat capacity, and ΔT is the temperature increase needed to reach the melting point. The current can be estimated using the formula I = Q / t, where I is the current, Q is the heat energy calculated earlier, and t is the time over which the heat is applied.
What is fusing current?
The fusing current is a value of current that causes the fuse to melt and interrupt the flow of current. Usually, reference is made to the minimum fusing current which is the smallest value of current that will cause the fuse to melt.
Why is my heat light connector melting?
It is either loose or corroded at the terminals inside causing the current to heat them up and in turn causing the plastic insulation to get hot and melt.
How does a cooler melt ice slower than the sun?
foam insulation
Why does Ice packed in sawdust not melt quickly?
Ice packed in sawdust does not melt quickly because sawdust acts as an insulator, reducing heat transfer between the ice and its surroundings. This insulation slows down the melting process by keeping the ice cold and preventing external heat from reaching it easily.
Difference between power and furnace transformer?
Power transformer is used step up or down the voltage for the electricity transmission while furnace transformer is used to melt the metals and ores in the electric furnace.
How do you fix insulation melt back on wire?
You cant it is physically impossible without a machine
Why do alligator wires not glow in a circuit?
Oh they will if there's enough current (amps) flowing through them. Then the insulation will melt with a sickly bouquet, and the wire may also melt. (Been there & done that.) It's preferable to avoid that, because you can only do it once with one alligator lead, and then you have to provide a new one.
What are the causes of fire in electrical circuits?
Overloading the circuit or a device like a power strip will cause the wiring to heat up at it's weakest point and can result in fire, it can also cause insulation to melt resulting in an electrical short.
What causes solids to melt?
fire/heat makes matter expand the melt away
