What happens if the voltage drop exceeds the maximum allowable percentage for a dwelling unit?

When the voltage drop in a dwelling unit exceeds the maximum allowable percentage, it can adversely affect the performance and longevity of electrical equipment. Electrical devices are designed to operate within specific voltage ranges, and a significant drop can lead to insufficient power being supplied to the equipment. This can result in inefficient operation, potential overheating, or, in more severe cases, complete failure of the device.

In many cases, prolonged exposure to undervoltage conditions can cause motors to overheat, reduce their lifespan, and lead to premature failure. Additionally, sensitive electronic devices may malfunction or experience data corruption as a result of inadequate voltage levels. Thus, maintaining voltage drop within acceptable limits is crucial for ensuring the functionality and safety of electrical systems in a dwelling.
