OW OW4X1,5 Electrical Cable 4×1.5 mm² 300/500V

OW OW4X1,5 is a four-core electrical cable with a conductor cross-section of 1.5 mm² and a rated voltage of 300/500V. The product provides four insulated conductors within a single outer sheath designed for low-voltage power distribution and fixed indoor installations. The compact construction allows routing in conduits, trunking or behind walls for lighting circuits, small appliance connections and branch wiring in residential and light commercial settings.

Advantages

The cable combines four separate insulated cores in one sheath to simplify installation and reduce the amount of individual conductors to run. With 1.5 mm² copper-equivalent conductors and a 300/500V rating, it is suitable for common lighting and small-load circuits. The single-sheath design offers protection against mechanical abrasion during installation and keeps cores organized for faster termination. The cable is intended for fixed indoor installation where the rated voltage and ambient conditions are respected.

Suitable for

• Wiring of lighting circuits in residential and commercial buildings
• Connections to switches, ceiling rose fittings and junction boxes
• Short runs to small household appliances and socket spur circuits (within applicable regulations)
• Installation inside conduits, trunking, or embedded in walls (indoor use)

Key specifications

• Number of cores: 4
• Conductor cross-section: 1.5 mm²
• Rated voltage: 300/500V
• Insulation: individually insulated cores within a single outer sheath
• Intended use: fixed indoor electrical installations

How to use

Plan the cable route and verify that the ambient conditions and installation method comply with local electrical codes. Cut the outer sheath carefully to expose the four insulated conductors, taking care not to damage their insulation. Terminate conductors at switches, fixtures or junction boxes using appropriate connectors or terminal blocks rated for 1.5 mm² conductors. Ensure secure fastening, proper earth/ground connection where required, and strain relief at entry and exit points. Do not use the cable for exposed outdoor runs or in applications exceeding its voltage rating.

Usage recommendations

Follow local wiring regulations and manufacturer guidance when selecting cable type, ensuring conductor sizing and installation practice match load, circuit length and protective device settings. For lighting and small-load circuits, verify that conductor cross-section and installation method are appropriate for the expected current and voltage drop. If in doubt, consult a qualified electrician.
