What is a potential problem of low supply voltage at startup?

Low supply voltage at startup can lead to device malfunction because many electrical appliances and equipment are designed to operate within a specific voltage range. When the voltage is lower than required, the electrical components may not receive enough power to function correctly. This can result in erratic behavior, diminished performance, or even the inability to start up at all.

It's important to ensure that the voltage supplied to the equipment meets its specifications to prevent issues during operation. For example, motors may stall, sensors may fail to trigger properly, and electronic circuits may not operate as intended. This highlights the significance of adequate voltage supply for reliable and efficient operation of commercial food equipment.

While increased operational costs and complete failure of equipment may be associated with low voltage conditions, the direct and immediate concern is usually the malfunction during startup, which confirms the validity of the chosen answer. Faster cooking times is not relevant in this context as low voltage would likely lead to slower cooking or ineffective heating rather than an increase in efficiency.
