NEMA publishes guidelines for expansion/deflection fittings.
Press Release Summary:
NEMA FB 2.40-2016 Installation Guidelines for Expansion and Expansion/Deflection Fittings provide recommended installation practices for fittings used to compensate for expansion and contraction in electrical raceways due to shear and lateral forces. When properly selected and installed, these fittings prevent harmful stresses in raceway system and to supporting structures by safely permitting 3-dimensional (linear, angular, and parallel) movement of raceway.

NEMA Publishes NEMA FB 2.40-2016 Installation Guidelines for Expansion and Expansion/Deflection Fittings
ROSSLYN, Va., —The National Electrical Manufacturers Association (NEMA) published NEMA FB 2.40-2016 Installation Guidelines for Expansion and Expansion/Deflection Fittings. These guidelines provide recommended installation practices for fittings used to compensate for expansion and contraction in electrical raceways due to shear and lateral forces. When properly selected and installed, these fittings prevent harmful stresses in the raceway system and to supporting structures by safely permitting three-dimensional (linear, angular, and parallel) movement of the raceway.
This new standard was produced jointly by the Conduit Fittings (5FB), Polymer Raceway Products (5TC), and Steel Rigid Conduit and Electrical Metallic Tubing (5RN) committees. Industries covered are: electrical contracting, construction, oil and gas, and utilities.
NEMA FB 2.40-2016 is available in hard copy for $72 and for electronic download at no cost on the NEMA website.
