Where to put the excess cable lengths?

Beke Nieszytka | 24. September 2019

If you are faced with the question of what to do with excess cable lengths on your system, you will quickly find terms like:

  • “Excess length drawer for storing cables”
  • Cable storage or cable manager
  • Cable storage for excess lengths
  • Cable bundle base
  • Switch cabinet base to accommodate cable bundles 
  • etc.

Well-known manufacturers such as Rittal, Blumenbäcker, Häwa, Jacob, Eldon, Lippert, ABB and KMK manufacture switch cabinets (wall-mounted switch cabinets, floor-standing cabinets, modular cabinets), terminal boxes, consoles as well as housings made of various materials. Plastic, aluminium, steel and stainless steel are often used for this purpose.

Switch cabinet base to accommodate excess length cables

How do these excess lengths arise?

Before you start thinking about how to store the cable lengths that are not actually needed and which system is best suited for this purpose, it is better to start with this question: how do these excess lengths actually occur?

Probably the best known term among electricians is the “fear metre”. There is almost no installer, assembler, switch cabinet builder or apprentice who hasn’t cut a cable too short when connecting and installing it on machines and industrial plant, only to find that a few centimetres are missing when trying to connect it to the consumer.

An incisive experience – one side connected, the cable creeping through the whole system, everything neatly laid … and now this! What do we take from it? If in doubt, cut or order one or two metres longer.

Extra long cables are cut off and end up in the cable scrap bin

Fatal – because now cables are being bought that are not needed for the machine to function. The extra long cable is cut off and transferred to the copper scrap. Or bases and storage compartments are purchased for valuable money. Added to this is the increased weight and rising transport costs as well as the not negligible topic of EMC (electromagnetic compatibility).

There is one case where there is no other way than to cut the cable a metre or two longer – the machine is located at a distance from the switch cabinet at the installation site that cannot yet be defined. The fear metre is to be regarded as a money waster, which modern CAD systems such as eplan, AutoCAD, Inventor, Solid Edge, etc. turn into a dinosaur in the industry.
