What is the maximum allowable voltage drop for low voltage circuits?

The maximum allowable voltage drop for low voltage circuits is typically set at 5% of the total circuit voltage. This standard is aimed at ensuring that the equipment receives adequate voltage for proper operation, which is critical for maintaining performance and efficiency. When voltage drop exceeds this threshold, it can lead to insufficient power being delivered to devices, potentially resulting in malfunction, reduced efficiency, or damage. Therefore, limiting the voltage drop to 5% helps to ensure that all components of the low voltage system operate reliably while minimizing potential issues related to insufficient voltage supply.
