Power Cable Pulling: CONDUIT_FILL_LIMIT
Power cable pulling tension limits, sidewall bearing pressure limits, friction coefficients, jam ratio thresholds, minimum bend radius multipliers, and NEC conduit fill limits. Covers copper (K=0.008) and aluminum (K=0.006) max tension by AWG/kcmil per ICEA P-79-561 / IEEE 1185-2019; SWBP limits for XLPE, EPR, PVC, armored, and lead-sheathed cables; COF by conduit type (steel/PVC/HDPE/FRP) and lubrication condition; jam ratio safe zones (danger: 2.7–3.1); NEC 300.34 bend radius multipliers.
