What is the consequence of using inadequate wire size?

Using inadequate wire size poses serious risks, primarily because it can lead to potential overheating and create a fire hazard. When the wire gauge is too small for the amount of current it carries, the wire experiences increased resistance, which generates heat as the current flows through it. This excessive heat can damage the insulation surrounding the wire, potentially leading to short circuits or exposure of live wires, both of which significantly increase the risk of fire incidents.

Moreover, the overheating can also result in the degradation of the wire over time, leading to premature failure of the electrical system. Thus, choosing the correct wire size is crucial for safety and effective operation of electrical circuits. Properly sized wires ensure that the current can flow without excessive resistance, maintaining a safe temperature and preventing hazardous conditions.
