  • Product description

    Copper installation cable NYM-J | 5×1.5 mm² | 300/500 V | white | 1 m | Lietkabelis KH05VV-U 5G1.5

    NYM-J 5×1.5 mm² – white copper cable with 5 solid conductors (L1, L2, L3, N, PE) for fixed electrical installation inside buildings. Manufacturer – AB Lietkabelis, designation KH05VV-U 5G1.5, rated voltage 300/500 V.

    Key point:
    A five-core cable is the universal three-phase solution: three phases, neutral N and protective PE. It suits both three-phase and mixed (three-phase + single-phase) loads.
    Number of cores
    5 (L1, L2, L3, N, PE)
    Cross-section
    1.5 mm²
    Typical protection
    B10 circuit breaker
    Installation
    Indoors

    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: L1, L2, L3, N, PE.

    Solid 1.5 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 (B10) and length (up to ≈ 45 m at 10 A), the circuit runs for years without overheating and the voltage drop stays within 3 %.

    Why choose NYM-J 5×1.5 mm²?
    It is a simple, reliable solution for a circuit where three-phase 400 V with neutral 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 – three-phase 400 V with neutral up to ~6.9 kW with B10 protection.
    • Solid class 1 conductors – reliable contact in screw and push-in terminals.
    • Colour-coded cores – L1, L2, L3, 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 5×2.5 mm² – larger cross-section – about 20–24 A, for longer runs or higher loads.
    • CYKY-L cable – black, also for outdoor and underground use with protection; NYM-J is for indoor use only.

    Where is it used?

    • Three-phase cookers and sockets.
    • Supply to flat and house sub-boards – according to incoming protection.
    • Workshops and garages – three-phase indoor circuits.
    • Mixed loads – where single-phase appliances are also supplied.

    Use by need

    House builder.
    Three-phase cooker, sub-board supply or three-phase socket with N and PE.
    Workshop or garage owner.
    A three-phase circuit that can also supply single-phase appliances.
    Electrical contractor.
    A universal three-phase cable for indoor wiring on projects.

    Practical example

    For example, a three-phase circuit with B10 protection has to be run to a cooker or workshop socket. NYM-J 5×1.5 mm² is suitable if the run is no longer than ≈ 45 m and the cable is not grouped 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.
    • 5×1.5 is not a single 7.5 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 5×1.5 mm² for a three-phase 400 V indoor circuit with neutral.

    5 × 1.5 mm²
    300/500 V
    B10
    Indoors
    Suitable when you need:
    • a three-phase 400 V circuit with N and PE;
    • protection by a B10 circuit breaker;
    • a run of up to ≈ 45 m at 10 A load.
    Check before ordering:
    • that the load and breaker match the 5×1.5 mm² cross-section;
    • that the circuit is no longer than ≈ 45 m at 10 A load;
    • that the cable will be installed indoors;
    • that you order enough length for connection.
    Important reminder: The 5×1.5 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 5×1.5 mean a total cross-section of 7.5 mm²?
    No. These are 5 separate 1.5 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 B10; 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.
