IEC 61914 Cable Cleats For Electrical Installations
IEC 61914 Cable Cleats For Electrical Installations defines Cable Cleats as “Devices designed to provide securing of cables when installed at intervals along the length of the cables”. In other words, they ensure the retention and support of cables, restrict the cable movement and provide resistance to electro-mechanical forces.

What is IEC?
The International Electrotechnical Commission (IEC) is the world’s leading organization that prepares and publishes International Standards for all electrical, electronic and related technologies. Millions of devices that contain electronics, and use or produce electricity, rely on IEC’s International Standards and Conformity Assessment Systems to perform, fit and work safely together.
What is IEC 61914:2015?
IEC 61914:2015 specifies requirements and tests for cable cleats and intermediate restraints used for securing cable in electrical installations, and assesses the performance and durability of a Cable Cleat’s Design.
Among other things, IEC61914 also provides formulas enabling the theoretical forces between conductors in the event of a short circuit to be calculated. (For information on how to Calculate the Correct Cable Cleat Spacing, CLICK HERE)
Although the standard doesn’t define pass or fail levels, it allows manufacturers to define the performance characteristics of their products. And also specifiers to compare products from different manufacturers. The aspects of construction and performance covered by IEC include:
- Material type – i.e. metallic, non-metallic or composite
- Minimum and maximum declared service temperatures
- Resistance to impact at the minimum declared operating temperature
- The ability of the cable cleat to withstand axial slippage forces
- Resistance to electro-mechanical forces (i.e. the ability of the cleat to withstand the forces between the cables in the event of a short-circuit fault)
- Resistance to UV and corrosion
- Flame propagation
Note: IEC 61914 does NOT apply to cable glands and cable ties!
