Where conduit is threaded in the field, what taper per foot should be used with a standard conduit cutting die?

The correct taper for threading conduit in the field with a standard conduit cutting die is 3/4 inch per foot. This specific taper is important because it ensures that the threads created are appropriately sized for the fittings that will be used with the conduit, providing a proper and secure fit. A 3/4 inch taper allows for efficient threading without compromising the strength or integrity of the conduit.

Using the correct taper helps to prevent issues such as cross-threading or misalignment when connecting conduits and fittings. Additionally, it contributes to the overall safety of the installation, as properly threaded conduit is less likely to come loose or experience failures due to poor threading. Familiarity with these specifications is essential for electrical contractors to ensure compliance with code requirements and industry standards.
