CE Rules for Bend Radii
The intent of the CE Code is to prevent cable
damage by over-bending, but its generic
nature requires installers to look deeper
into the topic.
Cable bending radius limitations are mainly
affected by conductor size, insulation thickness,
number of conductors, and shielding / armour
type. Most stated bend radius values are for
statically installed cables which become even
more critical when the cables are installed
under tension. Industry standards like IEEE
1185 provide general cable information, CE
Code rules provide code requirements, and
manufacturer spec sheets provide cable-
specific requirements. All should be
considered in your project.
Understanding cable bend radii can help
jobsite installations. Over-bending cables
may damage the jacket, armour, and/or
insulation, reducing cable life. Using too
large a bend radius can result in higher
cable tray costs.
Below are some of the main CE Code
bend radii rules for power and control cables.
12-110 Radii of Bends in insulated conductors
and cables – “The radii of bends in insulated
conductors and cables shall be sufficiently
large to ensure that no damage is done to
the conductors or cables or to their insulation,
covering, or sheathing.” This is a general rule
that applies to all conductor / cable types.
Additional code rules provide further
requirements for specific cable types.
