The 'Benfield Conduit Bending Manual, 2nd Edition' provides comprehensive guidance on bending electrical conduits with a focus on simplicity and precision. Authored by Jack Benfield, the manual covers various bending techniques, including 90° stubs, offsets, saddle bends, and the use of different benders. It emphasizes using basic arithmetic for calculations rather than complex mathematics, making it accessible for electricians. The manual also includes historical context about conduit bending tools and practical tips for achieving accurate bends in various materials like EMT and PVC.

What is the math for bending conduit?

It is important to understand the different elements of a bend in order to make accurate calculations. Calculating Wall Thickness. s=PN.(da-s/20.s)=PN.S. Calculating Standard Dimension Ratio. SDR = da/s. Calculating CLR (Center Line Radius) for Bend Angle. 3.1416(2x2.2) = 13.823/360 = 0.0384. 0.0384 x 35 = 1.344

How to calculate conduit bends?

On the conduit, measure from the free end to be bent up the calculated number and mark the conduit. As an example, to bend 3/4 EMT conduit have a free end height of 8.5, the table indicates to subtract 6 from the 8.5 which leave 2.5 from the end to bend up to make the mark.

How many inches do you add when bending conduit?

This means you need to add 5 inches to your total length for one 90-degree angle or 10 inches for two 90-degree angles over the length of the conduit. Measure and mark the conduit: Carefully measure the conduit with a tape measure and mark the length.

How many inches do you deduct for a 90 degree bend on 1 2 conduit?

For a 1/2 EMT conduit using a standard hand bender, the common take-up is 5 inches (C). Therefore, when you are planning where to make your bend, you would measure and mark your conduit, then subtract 5 inches from the length where the back of the 90-degree bend will be.

What is the bend rule for conduit?

The National Electrical Code (NEC), which sets the standard for electrical safety in the United States, has specific rules about conduit bends. For example, ing to the NEC, the total number of bends between pull pointssuch as junction boxes or fittingscannot exceed 360 degrees.

Do you add or subtract when bending conduit?

Subtract take-up from the desired stub height to calculate the starting point for the bend from the end of the pipe. To make an 11, 90 degree bend with 1/2 tube, allow 5 for take-up. Mark bend starting point on conduit (a distance of 6 from the end of the pipe for our example). NOTE: With a pipe, allow 6.

What is the 360 conduit bend rule?

ing to Sec. 358.26, the maximum degrees of bends permitted in one run is 360. To reduce the stress and friction on conductor insulation, the total bends (including offsets) between pull points cannot exceed 360.
