Introduction

Electrical Metallic Tubing (EMT) is a common conduit used in electrical installations. EMT hand benders are essential tools for electricians, allowing them to make precise bends in the conduit. Correct usage of an EMT hand bender requires understanding the mechanics and techniques, ensuring accuracy and safety in electrical installations.

Understanding EMT Hand Benders

EMT hand benders are specifically designed to bend conduits to specific angles. They come in various sizes, typically matching the diameter of the conduit being used. The bender shoe has angle markings, typically at 10°, 22°, 30°, 45°, and 90°, to guide the user.

Step-by-Step Guide to Using an EMT Hand Bender

Tools and Materials Required

• EMT conduit
• EMT hand bender
• Tape measure
• Marker
• Level
• Personal protective equipment (PPE)

Preparing the Conduit

Ensure the conduit is the correct length for the intended installation. Cut the conduit to size, removing any burrs to ensure smooth edges. Check the condition of the bender for any damage or wear that could affect accuracy.

Measuring and Marking

Measure the desired length from the end of the conduit to the start of the bend. Use a marker to indicate the starting point on the conduit. For consistent accuracy, use the bender's arrow or star as a reference mark.

Executing the Bend

Position the conduit in the bender, aligning the mark with the appropriate alignment guide on the bender. Hold the handle firmly, and apply steady pressure to begin bending the conduit. Ensure even pressure is applied to avoid kinks, and monitor the angle using the bender’s built-in indicators.

Continue the bend until the desired angle is achieved. For a 90° bend, ensure the bender is fully perpendicular to the ground for precision.

Final Checks

Use a level to verify the accuracy of the bend. If minor adjustments are needed, gently correct them by hand or with a slight application of the bender. Double-check measurements to ensure alignment with installation requirements.
