What is the maximum size of rigid conduit that can be bent by hand?
This keeps the raceway round in the bend and also keeps it from kinking. Rigid and IMC conduit are the hardest raceways to bend because they have a much thicker and harder wall. ½” and ¾” rigid or IMC can be bent by hand using a hickey (or segment bender).
How is rigid pipe measured?
Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS).
