Mercury 3 Core Round Mains Cable 1.5mm² Black - 100m Reel

The Mercury 3 core round mains cable is a 1.5mm² CSA flexible cable with a black PVC outer sheath, supplied on a 100m reel. Each core is constructed from 48 strands of 0.2mm copper wire, giving the cable flexibility for runs that need to navigate around obstacles or through conduit. The cable carries BSI BS6500 and VDE approval and is rated for 15A maximum current at 230V.

Designed for fixed electrical equipment, portable appliances and lighting circuits where three-core wiring is required, the cable suits both domestic and commercial installations. The round 8.7mm diameter profile allows it to be fed through standard cable glands and grips, and the black PVC sheath resists abrasion and moisture in typical indoor environments. Common applications include connecting stage lighting, PA equipment, portable tools and appliances that require earth continuity.

The 100m reel format suits electricians and installers working across multiple rooms or large spaces, reducing the need for mid-run joins. The flexible construction makes the cable easier to handle than solid-core alternatives when routing through tight bends or pulling through trunking. The black finish keeps the cable visually unobtrusive when surface-run along skirting or in visible locations.

What is the maximum current rating?

The cable is rated for 15A maximum at 230V. This suits most portable appliances, lighting circuits and electrical equipment up to approximately 3.45kW load.

Is this cable suitable for outdoor use?

The PVC sheath is moisture-resistant but the cable is primarily intended for indoor use. For permanent outdoor installations or buried runs, use cable specifically rated for outdoor or direct burial applications.

What do the individual cores represent?

In a three-core mains cable the cores are typically live (brown), neutral (blue) and earth (green/yellow). The exact core colours should be verified on the physical cable before termination.

Can this cable be used for stage lighting?

Yes. The 1.5mm² CSA and 15A rating suit most portable stage lighting applications where three-core cable is required. The flexible construction handles repeated coiling and movement better than solid-core alternatives.
