  • Product description

    Copper installation cable NYM-J | 3×6 mm² | 300/500 V | white | 1 m | Lietkabelis KH05VV-U 3G6

    NYM-J 3×6 mm² – white copper cable with 3 solid conductors (L, N, PE) for fixed electrical installation inside buildings. Manufacturer – AB Lietkabelis, designation KH05VV-U 3G6, rated voltage 300/500 V.

    Key point:
    A three-core cable is the standard for single-phase 230 V installation: phase L, neutral N and a green-yellow protective PE core. The 3×6 mm² size is usually paired with a 32 A circuit breaker.

    How it works

    The cable is installed permanently: in walls, under plaster, in conduits or trunking from the board to the load. Cores are connected by colour: L, N, PE.

    Solid 6 mm² copper conductors carry the current, while PVC insulation and the white sheath protect them mechanically and electrically. The continuous conductor temperature is up to +70 °C, so the current rating depends on how well the cable dissipates heat.

    With the right protection (32 A) and length (up to ≈ 30 m at 32 A), the circuit runs for years without overheating and the voltage drop stays within 3 %.

    Why choose NYM-J 3×6 mm²?
    It is a simple, reliable solution for a circuit where single-phase 230 V is needed: solid conductors are easy to terminate, the white sheath looks neat on surfaces, and you buy exactly as many metres as you need.

    ⚠ Check: values are indicative. Grouped cables, cables in thermal insulation or at higher temperatures have a lower rating. Protection follows IB ≤ In ≤ Iz; the final decision rests with the electrical design.

    Key functions

    • Power transmission – single-phase 230 V up to ~7.4 kW with 32 A protection.
    • Solid class 1 conductors – reliable contact in screw and push-in terminals.
    • Colour-coded cores – L, N, PE, faster and safer connection.
    • PVC insulation and sheath – double protection for indoor installation.
    • Sold by the metre – less waste and a more accurate estimate.

    How does it differ from similar cables?

    • NYM-J 3×4 mm² – smaller cross-section – about 30–36 A, for lighter loads or shorter runs.
    • CYKY-L cable – black, also for outdoor and underground use with protection; NYM-J is for indoor use only.

    Where is it used?

    • Flats and houses – single-phase circuits from the consumer unit.
    • Offices and commercial premises – lighting and sockets.
    • Dedicated appliances – where the load matches 3×6 mm².
    • Sub-board circuits – for single-phase loads.

    Use by need

    Flat or house owner.
    Lighting, socket or dedicated appliance circuit with PE to standard.
    Electrician.
    Solid conductors terminate quickly and hold their shape in boxes.
    Office or shop fit-out contractor.
    Many identical single-phase circuits bought to the exact length.

    Practical example

    For example, a single-phase circuit with a 32 A breaker has to be run from a flat's consumer unit. NYM-J 3×6 mm² with a PE conductor is suitable if the run is no longer than ≈ 30 m and the cable is not grouped with others or buried in thermal insulation.

    Pros

    • Solid copper conductors – hold their shape and terminate reliably.
    • White sheath – neat appearance for surface installation.
    • Made by Lietkabelis – established Lithuanian manufacturer with clear technical data.
    • Sold by the metre – pay only for the length you need.

    Cons / limitations

    • Not for direct burial or unprotected outdoor use – choose CYKY-L for that.
    • Not for portable equipment – solid conductors are not made for repeated flexing.
    • PVC insulation – where halogen-free cables are required, choose NHXMH-J.

    Safety and installation notes

    • Before work, isolate the supply, secure it against switching on and verify that no voltage is present.
    • Run cables in walls vertically and horizontally – so they aren't drilled later.
    • Strip cores with a proper tool without nicking the copper.
    • Before energising a new circuit, measuring insulation resistance is recommended.
    • Installation must be carried out by a qualified electrician.
    • 3×6 is not a single 18 mm² conductor.
    • The cable is not chosen by the breaker alone – installation method and circuit length are checked too.

    Quick selection guide

    Choose NYM-J 3×6 mm² for a single-phase 230 V indoor circuit with 32 A protection.

    3 × 6 mm²
    300/500 V
    32 A
    Indoors
    Suitable when you need:
    • a single-phase 230 V circuit with PE;
    • protection by a 32 A circuit breaker;
    • a run of up to ≈ 30 m at 32 A load.
    Check before ordering:
    • that the load and breaker match the 3×6 mm² cross-section;
    • that the circuit is no longer than ≈ 30 m at 32 A load;
    • that the cable will be installed indoors;
    • that you order enough length for connection.
    Important reminder: The 3×6 mm² designation alone does not define the maximum current or power. Choose the cable by load, installation method, circuit length and protective device.

    FAQ – frequently asked questions

    What is the difference between NYM-J and KH05VV-U?
    It is the same cable type: NYM-J is the common designation, KH05VV-U is the Lietkabelis product designation.
    Does 3×6 mean a total cross-section of 18 mm²?
    No. These are 3 separate 6 mm² cores.
    Can it be laid outdoors or underground?
    No. NYM-J is for indoor use; outdoors and underground choose CYKY-L, underground with mechanical protection and warning tape.
    Do you sell by the metre?
    Yes, the sales unit is 1 metre; for project quantities we prepare a quotation.
    Which circuit breaker should I choose?
    Usually 32 A; finally by load, installation method and circuit length (IB ≤ In ≤ Iz).
    Can it be installed under plaster?
    Yes, NYM-J is intended for installation in walls, under plaster, in conduits and trunking indoors.
