Procurement checklist before ordering

If you clarify these points before placing an order or making a project enquiry, you’ll reduce the need for follow-up enquiries, incorrect orders and unnecessary variants.

1. Application: What needs to be connected or powered?

2. Connections: Which connectors and device inputs are required?

3. Target market: Germany, Europe, an export market or multiple markets?

4. Technical specifications: Current, voltage, cross-section, data rate or fibre type.

5. Length: Standard length or project-specific dimensions?

6. Environment: Indoor, industrial, data centre, temperature or LSZH?

7. Quantity: One-off order, project quantity or series production?

8. Certifications: Are approvals, RoHS, REACH or other documents required?

9. Packaging: Bulk, polybag, retail packaging or project-specific?

10. Sourcing: Standard item or bespoke custom-made product?

3. Power, power cables, standards & international variants

When it comes to power cables, the procurement and engineering teams should not only consider the plug type. Other relevant factors include the target market, protective earth, IEC device-side specifications, current rating, cable length, cross-section, cable type, certification marks and the operating environment. For international projects, there is also the fundamental decision as to whether a country-specific power cable, an adapter solution or a standardised product family is the more economically and technically sensible procurement strategy.

Select a mains cable or IT extension lead directly

If the required combination has not yet been clearly determined, the MAG Cable Finder guides you step by step through the most important selection criteria and then to the appropriate product range.

Power cable or extension lead Destination country IEC appliance connection Power requirement Cable length Special requirements

Start the Cable Finder

Recommended order for selection

STEP 1 Target
market Determine the country and mains plug.

STEP 2 Device side
Check the IEC input and protection class.

STEP 3 Load
Match the rated current and cross-sectional area.

STEP 4 Design
Specify length, cable type and operating environment.

STEP 5 Approval
Check the certification marks and target market.

Country plugs & IEC equipment side

CEE 7/7, UK Type G, Swiss Type J, Danish Type K, US Type B, Indian Type D/M and other mains plugs must be suitable for the destination country and the appliance side.

Mains plugs worldwide → IEC 60320 appliance plugs → C13 / C15 / C17 → Select C13 / C15 / C19 →

Cross-section & cable designation

Specifications such as 0.75 / 1.0 / 1.5 mm², H05VV-F, H07RN-F, 3G1.5 or AWG help to classify the load, cable and operating environment.

Conductor cross-section → Cable designations → AWG & mm² →

Approval marks, LSZH & special cases

ENEC 10, VDE compliance, halogen-free LSZH cables, data centres/OCP and country-specific requirements should be taken into account at an early stage.

ENEC 10 & VDE → Halogen-free LSZH mains cables → OCP AC power cables →

Operational safety & international standardisation

For servers, PDUs, data centres, industrial applications and series projects, mechanically secured IEC connections and cable ranges suitable for international use can simplify procurement and operation.

Securing power cables against accidental disconnection → C13/C14 with multiple approvals →

International target markets: power cables, Type G or adaptors?

For export, roll-out and mass production requirements, the connection solution should be determined at an early stage. A mechanically compatible plug or adapter alone does not necessarily indicate suitability for the target market. The decisive factors are the type of application, device plug, protective earth conductor, current-carrying capacity, fuse protection and the certification documentation for the specific product.

Country-specific power cable

For mass-produced devices, OEM applications, export and permanently defined target markets, a suitable, complete power cable is often the neatest solution. It reduces the number of additional connection points and simplifies clear allocation to the target market.

Mains plugs worldwide → Power cable or adapter? →

Type G / BS 1363

For the UK and other Type G markets, the destination country, fuse, current-carrying capacity, cable and product-specific approvals must be considered together. The same plug shape does not automatically mean the same market suitability.

Type G: Countries, standards & approvals →

UK adaptors & conversion solutions

Plug-on adapters, mountable adapters and conversion plug solutions serve different purposes. When purchasing and planning projects, decisions should therefore be based not only on the design but also on the intended use and specific approvals.

4. Data cables, LAN, fibre optic, USB-C & video

Data and signal cables should be selected according to their intended application. Data rate, length, shielding, PoE power, fibre type, connector combination, charging power, video transmission and operating environment determine functionality, stability and support requirements. For procurement and roll-outs, it is advisable to define these requirements as project standards before selecting specific items.

USB-C & USB4

USB-C primarily refers to the connector type. Charging power, data rate, video, Power Delivery and E-Mark must be suitable for the application. For standardised workstation or docking projects, the required range of functions should be defined in advance.

USB-C selection guide → Thunderbolt or USB4 →

LAN, Ethernet & PoE

For LAN projects, the category, shielding configuration and PoE requirements should be defined together. Cat 6A, Cat 7 or Cat 8, U/UTP to S/FTP, as well as PoE, PoE+ or PoE++ are different selection criteria and should not be confused with one another.

Cat 6A / Cat 7 / Cat 8 → LAN shielding → PoE & AWG → LAN range →

Fibre Optics

For fibre optic projects, the fibre type and range are determined first, followed by the connectors. OM3, OM4 or OS2, as well as LC, SC or ST, must be compatible with the existing infrastructure, the transceivers and the application.

Select OM3 / OM4 / OS2 → Select LC / SC / ST → Fibre Optics Range →

Video & Monitor

Resolution, refresh rate, cable length, device port, signal standard and installation environment determine the appropriate connection. For roll-outs, the cable standard and maximum required resolution should be defined uniformly.

Video & Monitor →

Define network and fibre optic procurement in advance

Particularly for rollouts, data centres and recurring procurement, it is worth defining a few clear project standards. This helps to reduce the number of variants and simplify subsequent orders.

1. Data rate: Specify the required Ethernet or interface performance.

2. Distance: Define the cable length and installation environment.

3. Shielding / Fibre: Specify LAN shielding or multimode/single-mode.

4. Power / PoE: Take into account PoE power and the appropriate conductor size.

5. Connectors: Clearly define RJ45, LC, SC, ST or other connectors.

Guide or Cable Glossary?

This section helps with the selection and procurement process. If you need to clarify individual terms, standards, connectors or technical differences in detail, use the Cable Glossary from A to Z .

5. Avoid common selection errors

Area	Typical mistake	Check more carefully
Power cables	Selected solely on the basis of the plug shape	Check the target market, protective conductor, IEC side, cross-sectional area and test mark together
IEC equipment end	C13, C15 and C17 selected solely on the basis of similar shape	C14/C16/C18 appliance inlets: take temperature requirements and protective earth into account
International projects	A mechanically compatible plug is considered equivalent to market suitability	Match target market, national approvals, cable, voltage/current and appliance end
UK / Type G	Plug-on adaptors, mountable adaptors and conversion plugs are regarded as equivalent	Check the type of use, existing appliance plug, fuse, protective earth and specific approval of the item
USB-C	USB-C is automatically considered to have full functionality	Check charging, data rate, video, docking, Power Delivery and E-mark
LAN / PoE	Selected solely by Cat category, or PoE requirements only considered at a late stage	Determine category, shielding, length, solid copper conductors, AWG and required PoE power jointly
Fibre	Fibre type or end-face finish not clearly specified	Check OM3/OM4/OS2, single-mode/multi-mode, LC/SC/ST, APC/UPC and existing infrastructure
Project requirements	Documentation and master data requested too late	Plan for documents, product data, part numbers and approvals at an early stage
