About Voltage Drop
Voltage drop is the reduction in voltage in an electrical circuit between the source and load. Excessive voltage drop can cause:
- Poor equipment performance
- Overheating of wires and equipment
- Reduced efficiency
- Potential safety hazards
Generally, a voltage drop of less than 3% for lighting circuits and 5% for power circuits is considered acceptable.
