- Formula traceCircumference = π × 24 = 75.4
- Formula tracePlanned coverage = 75.4 (circumference) × (1 + 5%) = 79.17
- Formula tracePads / band = ceil(79.17 ÷ 10) = 8
- Formula traceTotal pads = 8 × 1 band(s) × 2 zone(s) = 16
- Formula traceTotal load = 16 × 3600 W = 57.6 kW
- Formula traceHeater output current / pad = 3600 W ÷ 80 V = 45 A
- Formula traceEstimated source input = 57.6 kW ÷ 90% entered efficiency = 64 kW
- Formula trace3-phase source line-current estimate = 64 kW ÷ (√3 × 480 V × 1 PF) = 76.98 A
- Formula traceGenerator estimate = 64 kW ÷ (1 PF × 80% utilization) = 80 kVA
- Formula traceHeater circuits / zone = ceil(8 pads ÷ 1 whole pad(s) per circuit) = 8
- Formula traceExtension-lead voltage drop = 45 A × 0.4 Ω / 1000 ft × 200 ft = 3.6 V (4.5%)
