Backline Power & Voltage Drop Calculator
Safeguard Backline Rigs & Prevent Voltage Brownouts
Long feeder cable runs from main generator distros to stage-left audio racks can introduce significant voltage drops under high current draw. The Backline Power & Voltage Drop Calculator helps master electricians and sound crews compute phase balances, conductor gauge requirements (AWG / mm²), and peak current capacity.
Electrical Calculation Features
- 3-Phase Load Balancer: Distribute single-phase audio, lighting, and LED wall loads evenly across L1, L2, and L3 phases.
- Voltage Drop Formula: Instant calculation of V-drop over distance (ft/m) based on conductor gauge (4/0 Cam-Lok, 2/0, 10 AWG).
- Neutral Current Risk Warnings: Detect harmonic neutral overheating risks caused by non-linear switch-mode power supplies (SMPS).
- Generator KW Load Estimator: Compute total continuous kVA and surge requirements for temporary concert generators.
