What H07RN-F means, where the rubber flexible cable can be used, how it differs from H05RN-F and H07RN8-F, and what to check before ordering for EU projects.
If there is one flexible cable that every European contractor, rental company and machine builder keeps in stock, it is H07RN-F. It powers site distribution boards, pumps, compressors, temporary lighting and mobile machinery from Lisbon to Helsinki. Because it is a harmonised cable type, the same designation means the same construction in every EU country — which makes it easy to specify, but also easy to buy badly.
This guide explains what the designation tells you, where H07RN-F is (and is not) the right choice, and the checks we recommend before you place an order.
H07RN-F is a harmonised designation under the EN 50525 series (the rubber flexible cables are covered in EN 50525-2-21). Each part of the code describes the construction:
A typical order line therefore reads, for example, H07RN-F 5G2.5: five cores, one of them green-yellow (the “G”), each of 2.5 mm². For a full explanation of the letter system, see our article on harmonised cable codes.
The combination of rubber insulation and a polychloroprene sheath makes H07RN-F suitable for medium mechanical stress in dry, damp and wet environments, indoors and outdoors. Typical uses include:
You can review the full construction and dimension table on our H07RN-F industrial cable page, including cross-sections from single-core 1.5 mm² upwards.
These three are often confused, and the wrong choice usually shows up only after installation.
| Type | Rated voltage | Typical use |
|---|---|---|
| H05RN-F | 300/500 V | Light mechanical stress: small tools, light-duty appliances |
| H07RN-F | 450/750 V | Medium mechanical stress: site equipment, motors, mobile machinery |
| H07RN8-F | 450/750 V | Same duty as H07RN-F, with a construction intended for use in water |
H05RN-F is lighter and cheaper, but it should not be used where the cable is dragged across a site or run over. H07RN8-F is the version to look at when the cable will be permanently or regularly submerged, for example on dewatering pumps or fountains. For deep-well and borehole pumps, a dedicated submersible pump cable rated AD8 is usually the safer specification.
Some applications push standard H07RN-F to its limits: cables dragged over concrete every day, frequent coiling and uncoiling on rental fleets, or cold-climate use. For those, a heavy-duty H07RN-F with a reinforced sheath and better low-temperature flexibility extends service life considerably. The price difference is small compared with the cost of replacing damaged leads and the downtime involved.
For European projects, the supplier should be able to provide a datasheet showing construction and dimensions, the harmonisation or third-party certificate, a declaration of conformity referring to the Low Voltage Directive, and RoHS and REACH statements. If the cable will be installed permanently in a building, also read our guide to CPR cable classes, because a Declaration of Performance may then be required.
We source H07RN-F and its variants in standard cross-sections and in project quantities, check the documentation before shipment, and can arrange independent sample testing when a project requires it.

Yes. The polychloroprene sheath of H07RN-F resists weather, UV, ozone and oil, so it is widely used outdoors on construction sites and in industry. Check the temperature range on the datasheet for very cold climates and choose a heavy-duty version if the cable will be dragged or run over frequently.
Both are 450/750 V rubber flexible cables. H07RN8-F has a construction intended for use in water, for example on submersible pumps or in fountains, whereas standard H07RN-F is designed for wet and damp conditions but not for permanent immersion.
Only when it is placed on the market for permanent installation in a building or civil engineering work. For mobile equipment and temporary installations, the CPR does not normally apply, but the cable must still comply with the Low Voltage Directive and RoHS.
