Cable Cleats | A Device For Short Circuit Protection | CPD Course By Ellis Patents
March 29th, 2022
Cable Cleats
A Device For Short Circuit Protection
Ellis Patents, the world’s leading cable cleat manufacturer, has launched its UK accredited Continuing Professional Development (CPD) course – developed in-house, their online CPD course has helped educate thousands of engineering professionals from around the world.
“Cable cleats: a device for short circuit protection” is a NBS RIBA accredited course designed to provide technical insight and guidance that has been adapted for international use and is available through Ellis’s e-learning portal.

Cable Cleats CPD Course Content
Module 1 Introduction
Includes a brief history of standards plus the importance of detailed specification to ensure the correct cable fixings are chosen for the environmental conditions and application.
Module 2 Electrical Theory
Nothing too heavy! Learn about short circuit faults, why they occur and their impact on cable systems. Also, how to calculate the forces involved and therefore how to ensure the correct strength fixings are specified.
Module 3 Materials
Different applications require differing solutions. Learn how sunshine, pollution and marine environments can cause problems if the wrong materials are specified. How to avoid bimetallic issues and how to prevent corrosion. The importance of fire safety and low emissions is also studied.
Module 4 Testing
Some exciting video clips of when things go wrong, and of good engineering practice. Appreciate the international standards that apply to cable cleat design and the rigorous testing procedures involved.
Module 5 Applications
An overview of some cable cleating applications and interesting special cable fixing projects.
What are the people saying?
“The Ellis CPD training is beneficial because it covers technical aspects of selecting the right cleat and it allowed me to discuss cleats with much more confidence.”
Rob Rehberg (NASCO)
“I found the Ellis Cable Cleats CPD kept my interested, it was very informative and professionally put together.”
Jon Watkins (Electrical Engineer – Kier Construction)
In this video Ellis Patents compare using Stainless Steel Cable Cleats and Stainless Steel Cable Ties – the Ellis cable cleats are used to restrain power cables on slotted rung cable tray and are short-circuit tested to 59kA RMS, 118kA Peak for 0.1 second duration.
SHORT-CIRCUIT TESTING
There is a major difference between the short-circuit withstand requirements of a cable and the short-circuit withstand of a cable cleat.
The former is concerned with cable degradation as a result of temperature rise (thermal stress heating), while the latter is concerned with cable retention as a result of electromechanical forces.
Typical installation specifications that have been derived from the thermal withstand of the cable would require a short-circuit withstand of 63kA for 1 second or 40kA for 3 seconds.
A short-circuit test for a cable cleat does not consider this heating effect, and instead concentrates entirely on the destructive electro-mechanical forces at peak, followed by a short term decaying RMS.
The international standard IEC 61914 requires a short-circuit test duration of just 0.1 second. This equates to five complete cycles, by which time the true strength of a cable cleat will be known.
IEC61914 notes “a cable cleat is provided with a means of attachment to a mounting surface but does not rely on an unspecified mounting surface for the retention of the cables. Examples of mounting surfaces that may be specified are ladder, tray, strut or rail, wire and beam. Where declared, cable cleats provide resistances to electromechanical forces.”
