What happens if the voltage drop exceeds the NEC recommended limits?

If the voltage drop exceeds the National Electrical Code (NEC) recommended limits, it can lead to inadequate performance of electrical devices. Electrical devices are designed to operate within specific voltage ranges. When the voltage falls below these levels due to excessive voltage drop, devices may not function effectively, leading to issues such as diminished performance, erratic operation, or even failure to operate at all. This is particularly important in systems with sensitive electronics, where precise voltage is crucial for operational integrity.

While it is essential to adhere to NEC recommendations to ensure equipment operates efficiently, it is also true that excessive voltage drop does not enhance safety, nor does it typically increase the lifespan of devices or improve energy efficiency. Instead, maintaining proper voltage levels helps ensure both optimal performance and longevity of the equipment.
