Yes, if the overcurrent is not quickly detected by a fuse or circuit breaker, the conductors will heat up from the excessive current, causing the resistance to increase, causing more heat, causing more resistance. This "thermal runaway" continues until the heat gets high enough to damage or destroy the insulation (if any) on the conductors, and deform the conductors to the point of separation. Overheated conductors may possibly reach the ignition temperature of adjacent materials, either with the conductor, sparks from arcing, or from molten insulation, resulting in a Class C fire.

What is a fuse in an electrical appliance?
A fuse is a safety device that protects electrical appliances from overcurrent or short circuits. It is designed to melt and break the circuit if the current exceeds a safe level, preventing damage to the appliance or a potential fire hazard. Fuses need to be replaced once they have blown to restore the electrical circuit.
How does a car catch on fire while idle?
Several things can cause a fire. A fuel leak or transmission fluid dripping on a hot exhaust can cause a fire, or an electrical fire can occur from a short in the system.
What electrical codes?
Electrical codes or the NFPA70 and the standers for electrical work and are in place to protected the public from bad wiring that can cause fire's and other hazards
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 permanent damage to computer components?

What are electrical fuses?
Safety devices used in electrical circuits.AnswerA fuse is an overcurrent protection device, and will operate in the event of a sustained overload current or a short-circuit current.
Which effect of electric current is utilised in the working of an electrical fuse?
The heating effect is used. Normally the current flows through the fuse without undue heating. But if too much current passes through, the fuse will heat and melt, thus stopping the current which could cause a fire if it was not stopped .
Why should water not be used to put out an electrical fire or fire in a petrol tank?
Water is a conductor of electricity, so using it to put out an electrical fire can result in electric shock or spreading the fire. In the case of a petrol tank fire, water is denser than petrol and can cause the petrol to spread, making the fire larger. It may also cause an explosion due to the rapid vaporization of water.
Water should never be used to fight which type of fire and why?
Water should never be used to fight an electrical fire. It could potentially cause an explosion or cause you to become electrocuted.
