Mercury 3 Core Round Mains Cable 0.5mm² Black - 100m (3 x 16/0.2mm)

The Mercury 3 core round mains cable is a 100m reel of flexible PVC-sheathed cable with a 0.5mm² cross-sectional area, rated for a maximum 3A current. The cable comprises three conductors, each containing 16 strands of 0.2mm diameter copper wire, giving the cable flexibility for routing through conduit, around corners and through tight spaces during installation.

Designed for light electrical applications including table lamp and floor lamp wiring, low-power control circuits, and appliance connections where the load does not exceed 3A at mains voltage. The black PVC outer sheath provides abrasion resistance and insulation, with an overall cable diameter of 5.6mm that fits standard cable clips and grommets. The 100m reel length suits commercial installations, contractor work and workshop stock where multiple runs are needed from a single reel.

The cable carries both BSI BS6500 and VDE certification, confirming compliance with British and European safety standards for flexible cabling. The round profile and multi-strand construction make it easier to handle than solid-core alternatives, particularly where the cable needs to be routed through existing installations or bent around obstacles. The black sheath blends with most electrical accessories and mounting hardware without drawing attention to the cable run.

What applications is this cable suitable for?

The 0.5mm² CSA and 3A rating make it suitable for table lamps, floor lamps, low-power control circuits, and light electrical appliances that draw under 3A at mains voltage. It is not suitable for higher-load appliances like kettles, heaters or power tools.

What are the conductor colours inside the cable?

Standard 3 core mains cable typically contains brown (live), blue (neutral) and green/yellow (earth) insulated conductors. Confirm conductor colours before terminating by inspecting the cable end.

Can this cable be used outdoors?

The PVC sheath provides basic protection from moisture and abrasion, but this cable is not rated for direct burial or permanent outdoor exposure unless run through weatherproof conduit or trunking. For outdoor lighting circuits, consider cable rated for outdoor use.

Is the cable flexible enough for pendant light installations?

Yes. The multi-strand construction (16 x 0.2mm per conductor) gives the cable flexibility for routing through ceiling roses, suspension fittings and around obstacles. The 5.6mm diameter fits standard pendant grips and ceiling rose entry points.
