Calculate conduit bending measurements for offsets, kicks, and three-point saddles with accurate multipliers and deductions.
Conduit bending is a fundamental skill for electricians, requiring precise measurements and angle calculations to create professional installations. Understanding bending multipliers, deductions, and gain factors ensures accurate bends that maintain proper conduit fill and minimize pulling stress on conductors. Whether creating offsets to navigate obstacles, kicks for transitions, or saddles to cross obstructions, proper bending mathematics prevents costly mistakes and rework.
Common bends include offset bends (parallel displacement using two equal angle bends), kick bends (90-degree transitions), and three-point saddles (crossing over obstacles). Each bend type uses specific multipliers: 10° = 6.0, 22.5° = 2.6, 30° = 2.0, 45° = 1.4, and 60° = 1.2. Deduction values vary by conduit size and account for the bend radius, ensuring accurate stub-up measurements.
