Germany and Europe International plug systems IEC 60320 Project and production requirements

Please check the mains and equipment specifications, rated values, conductor cross-section, cable length, and product-specific standards and approvals before placing your order.

Choosing the right power cables and extension leads for IT equipment

To ensure a reliable power connection, the connectors, device connection, power requirements, cable and application must all be compatible. The first crucial factor is whether a connection from the socket to the device is required, or whether an existing IEC 60320 power connection needs to be extended.

The DINIC range includes national and international power cables, extension cables for low-voltage and high-voltage equipment, as well as complementary solutions for IT, PDUs, UPSs, servers, industry, equipment manufacturing, export and project requirements.

Power cables or power extension leads – which do I need?

Power cable: socket → device

A power cable connects a mains socket to the device. On the mains side, for example, there is a safety-pin plug, Euro plug, NEMA plug, UK plug, Swiss plug or other country-specific plug.

On the appliance side, IEC 60320 connectors such as C7, C5, C13, C15 or C19 are frequently used.

IEC extension cable: IEC → IEC

An IEC extension cable does not start at a wall socket, but at an existing IEC power source, such as a PDU, UPS or power distribution unit.

The existing output and the equipment input together determine the required plug combination.

Correctly identifying the IEC equipment connection

With IEC 60320 connections, the cable connector and the equipment input are labelled differently. It is therefore important to identify the actual connection on the equipment when making your selection.

Common correspondences

  • C8 equipment input → C7 on the connection cable
  • C6 appliance input → C5 on the connection cable
  • C14 appliance socket → C13 on the connection cable
  • C16 appliance input → C15 on the connection cable
  • C20 device input → C19 on the connection cable

Power source for extension leads

When using power extension cables, the existing IEC output must also be taken into account. For example, a standard C13/C14 connection is selected differently from a C19/C20 power path.

The MAG Cable Finder therefore checks both the existing connection and the input on the target device when selecting extension cables for IT equipment.

Important: A mechanically feasible plug combination does not automatically mean that it is suitable for the desired electrical load. The current class, cable, cross-section, connectors and technical approval of the complete connection must all be compatible.

Typical areas of application

IT, servers & data centres

  • PCs, monitors and workstation technology
  • Servers, switches and storage systems
  • PDU and UPS power connections
  • Rack and data centre cabling
  • Coloured power pathways and structured installations

Industry, OEM & Export

  • Machinery and industrial equipment
  • Measurement, testing and laboratory technology
  • Equipment manufacturing and series production
  • International equipment supply
  • Service and spare parts supply
Mains cables for export: For international applications, the shape of the mains plug alone is not sufficient. The destination country, mains voltage, equipment input, power requirements, cable design, as well as the test marks and approvals specified on the specific item must be taken into account.

Power cable or power adaptor?

A suitable country-specific power cable is often the direct connection solution for permanently installed equipment, export products, mass-produced devices and professional installations. A power adapter, on the other hand, may be appropriate if only a suitable mechanical connection is required for a specific application.

Important note on international power adapters: A mechanical power adapter does not convert mains voltage or frequency. Before use, you must check whether the connected device is suitable for the mains supply in the country in question.

Frequently asked questions about power cables and extension leads for low-voltage equipment

What is the difference between a mains cable and a low-voltage extension lead?

A power cable connects a wall socket or a country-specific mains connection to the device. An extension lead for low-voltage equipment, on the other hand, extends an existing IEC 60320 power connection – for example, from a PDU or UPS – to the connected device.

Which power cable is suitable for my device?

The key factors are the mains plug or destination country, the device’s input, power requirements, protection class, cable length, cable type and the technical specifications of the specific product. The MAG Cable Finder helps with the initial selection.

Which power extension lead do I need?

First check the existing IEC output on the power source and then the input on the target device. To do this, the power requirement, cable type, cross-section and the permissible rated values of the entire connection must all be compatible.

What is the difference between C13 and C14?

C13 refers to the commonly used IEC ‘cold appliance’ connector on the cable. C14 is the matching counterpart and is found, for example, as a device input or on IEC power distribution units.

When are C19 and C20 used?

C19/C20 is used for higher-power IEC power connections designed accordingly and is found, amongst other things, in PDU, UPS, server, storage and industrial applications. The rated values of the specific device and cable are always decisive.

When do I need a C15 instead of a C13?

C15 is combined with a C16 equipment input and is intended for applications with higher temperature requirements at the connector. For a C16 input, a suitable C15 version should therefore be selected.

Can the MAG Cable Finder also select international power cables?

Yes. For mains cables, you can first select the target market. The Finder then takes into account the appliance input, power requirement, cable length and other requirements, and directs you to the appropriate range.

Does the Finder also check for extension leads for low-voltage equipment?

Yes. For extension cables for low-voltage equipment, the existing IEC connector and the equipment input are queried. In addition, power requirements, length and other requirements are taken into account to rule out technically unsuitable combinations as early as possible.

Does a larger conductor cross-section automatically allow for a higher current?

No. The conductor cross-section is only one part of the technical design. Other crucial factors include connectors, cable type, rated values, cable length and the approval of the complete connection cable.

When is a country-specific mains cable better than an adapter?

For export devices, mass-production requirements and permanent professional installations, a suitable country-specific power cable is often the more straightforward solution. However, the device, target market and technical product data must be checked for every application.

Are customised power cables and IEC extension cables possible?

Depending on technical feasibility, project-specific requirements such as special cable lengths, colours, cross-sections, angles, plug configurations, labelling and packaging solutions can be assessed.

Power cables and IEC extension cables for OEM and mass-production projects

If the required design is not available as a standard item, customised cable and adapter solutions can be assessed. Depending on the project, different lengths, colours, cross-sections, plug combinations, angle variants, markings or packaging options may be possible, for example.
