This calculation determines the length of underground AC wire based on the volume of conductor material and the cross-sectional area of the wire. It's particularly useful for 1-phase 2-wire US electrical systems to estimate wire length requirements.
The calculator uses the formula:
Where:
Explanation: The formula calculates wire length by dividing the total conductor volume by twice the cross-sectional area (accounting for both conductors in a 2-wire system).
Details: Accurate length calculation is crucial for proper material estimation, cost calculation, and ensuring adequate conductor length for underground AC electrical installations.
Tips: Enter conductor volume in cubic meters and wire cross-sectional area in square meters. Both values must be positive numbers greater than zero.
Q1: Why is the volume divided by 2 times the area?
A: For a 1-phase 2-wire system, there are two conductors, so the total length calculation accounts for both conductors in the system.
Q2: What units should be used for input values?
A: Volume should be in cubic meters (m³) and area in square meters (m²) for consistent results in meters for length.
Q3: Can this formula be used for other wire types?
A: This specific formula is designed for 1-phase 2-wire US underground AC systems. Other configurations may require different formulas.
Q4: How accurate is this calculation?
A: The calculation provides theoretical length based on volume and area. Actual installation may require additional length for connections, bends, and safety margins.
Q5: What if I have different measurement units?
A: Convert all measurements to consistent units (preferably meters for length, square meters for area, and cubic meters for volume) before calculation.
