How to Calculate Conduit Shrink Per Inch of Offset with 30 Degree Bends?

What is the conduit shrink per inch of offset when using 30 degree bends?

How does the conduit shrink per inch of offset change with different types of conduits and bends?

Answer:

The conduit shrink per inch of offset when using a 30 degree bend is not a standard value. It depends on the type of conduit and the nature of the bend. In general electrical work, a 30-degree bend results in about a 1/6 shrink, so for every 6 inches of offset, the conduit shrink is about 1 inch.

When calculating conduit shrink per inch of offset with 30 degree bends, it is important to consider the specific type of conduit and the angle of the bend being used. Different materials and designs will yield different results in terms of the amount of shrinkage per inch of offset.

For electrical work, a 30 degree bend typically results in a 1/6 shrink, which means that for every 6 inches of offset, the conduit will shrink by approximately 1 inch. This concept is crucial in ensuring that electrical wires are properly routed and installed within a building.
