What could be a consequence of not checking the supply voltage?

Not checking the supply voltage can lead to potential damage to the equipment because electrical devices are designed to operate within specific voltage ranges. If the voltage supplied deviates from these acceptable levels—either being too high or too low—it can cause various issues.

For instance, excessive voltage can result in overheating, burnout of components, and ultimately malfunction or complete failure of the device. Conversely, insufficient voltage can lead to underperformance and may also strain the equipment, leading to premature wear and potential damage. Ensuring the correct supply voltage helps to maintain the integrity and functionality of the equipment, thus avoiding the costly repercussions associated with repairs or replacements.

In contrast, options related to increased efficiency, reduced risk, or lower operational costs would not be realistic outcomes of neglecting voltage checks, as those factors are directly threatened by improper voltage conditions.
