1. What is Conduit Shrink Calculation?

Conduit shrink calculation is used in electrical work to determine how much a conduit will shorten when making bends. This is essential for accurate measurements and proper installation of electrical conduits.

2. How Does the Calculator Work?

The calculator uses the conduit shrink formula:

Where:

• \( CS \) — Conduit shrink (in)
• \( O \) — Offset (in)
• \( A \) — Bend angle (degrees)

Explanation: The formula calculates how much length is lost when bending conduit at various angles, with 90 degrees as the reference point.

3. Importance of Conduit Shrink Calculation

Details: Accurate conduit shrink calculation is crucial for proper electrical conduit installation, ensuring bends are made correctly and the conduit reaches its intended destination without being too short.

4. Using the Calculator

Tips: Enter offset in inches and bend angle in degrees. All values must be valid (offset > 0, angle between 1-180 degrees).

5. Frequently Asked Questions (FAQ)

Q1: Why is conduit shrink important in electrical work?
A: Conduit shrink calculations ensure that conduits are cut to the correct length before bending, preventing waste of materials and ensuring proper fit.

Q2: Does this formula work for all conduit types?
A: This formula provides a general calculation that works for most conduit types, though specific conduit materials may have slightly different shrinkage characteristics.

Q3: What's the difference between offset and shrink?
A: Offset is the distance the conduit needs to move, while shrink is the amount of length lost due to the bending process.

Q4: Are there different formulas for different bend angles?
A: This formula works for any bend angle, using 90 degrees as the reference point for calculation.

Q5: How accurate is this calculation in real-world applications?
A: While this formula provides a good estimate, experienced electricians often make minor adjustments based on the specific conduit type and bender being used.
