Practical Example
Let’s consider a practical example to illustrate the use of an online voltage drop calculator.
Scenario: You are designing a circuit for a new lighting system in a warehouse. The system will use copper conductors, with a total circuit length of 200 feet, carrying a current load of 20 amps, and operating at 120 volts.
Steps:
- Conductor Material: Copper
- Conductor Size: 10 AWG (American Wire Gauge)
- Circuit Length: 200 feet
- Current Load: 20 amps
- Voltage: 120 volts
Using these inputs, the calculator might show a voltage drop of 3.84 volts, which is 3.2% of the operating voltage. If this drop is within acceptable limits (typically below 5%), the design is considered efficient.
