1. What is Voltage Drop in Parallel Feeders?

Voltage drop refers to the reduction in voltage in an electrical circuit between the source and load. For parallel feeders, multiple conductors share the current load, which affects the overall voltage drop calculation.

2. How Does the Calculator Work?

The calculator uses the voltage drop equation for parallel feeders:

\[ VD = \frac{I \times L \times R}{n \times V} \]

Where:

\( VD \) — Voltage drop (volts)
\( I \) — Current (amperes)
\( L \) — Length of conductor (feet)
\( R \) — Resistance per unit length (ohms/ft)
\( n \) — Number of parallel feeders
\( V \) — System voltage (volts)

Explanation: The equation calculates how much voltage is lost due to conductor resistance over a given length, accounting for multiple parallel conductors sharing the current.

3. Importance of Voltage Drop Calculation

Details: Proper voltage drop calculation ensures electrical equipment receives adequate voltage to operate correctly. Excessive voltage drop can cause equipment malfunction, reduced efficiency, and potential safety hazards.

4. Using the Calculator

Tips: Enter current in amperes, length in feet, resistance in ohms per foot, number of parallel feeders, and system voltage. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's an acceptable voltage drop percentage?
A: Typically 3% for branch circuits and 5% for feeder circuits is considered acceptable, but check local codes for specific requirements.

Q2: How does parallel feeders affect voltage drop?
A: Parallel feeders reduce voltage drop by dividing the current among multiple conductors, effectively lowering the resistance seen by each current path.

Q3: What factors affect conductor resistance?
A: Conductor material, size, temperature, and frequency (for AC systems) all affect resistance.

Q4: Should I include both supply and return conductors in length?
A: For single-phase AC or DC systems, yes. For balanced three-phase systems, use the actual one-way length.

Q5: How does this apply to horse facilities?
A: Proper voltage drop calculation is crucial in barns and stables to ensure reliable operation of lighting, ventilation, and other electrical equipment that affects animal welfare.
