Hand benders are manufactured to bend EMT in sizes 1/2-inch to what, and Rigid in sizes 1/2-inch to what?

The correct answer is based on the manufacturing standards for hand benders used in electrical work. Specifically, hand benders are typically designed for bending EMT (Electrical Metallic Tubing) and Rigid conduits within certain size ranges.

For EMT, hand benders are typically manufactured to accommodate sizes starting from ½-inch up to 1¼-inch. This is a commonly accepted standard in the electrical industry, allowing electricians to work with the most common conduit sizes used in installations.

When it comes to Rigid conduit, hand benders are generally manufactured for sizes from ½-inch up to 1-inch. This size limitation is due to the increased thickness and rigidity of the Rigid conduit compared to EMT. Bending larger sizes of Rigid conduit often requires specialized bending equipment due to the greater force needed for the thicker material.

Thus, the correct answer reflects these industry standards: hand benders can effectively handle EMT sizes from ½-inch to 1¼-inch, and Rigid sizes from ½-inch to 1-inch. This alignment with common practices in the field ensures safety and effectiveness during installation tasks.
