Solar PV Cable 4 mm² Red – Per Metre is a single core solar photovoltaic cable for DC wiring between solar panels, combiner boxes, isolators and inverters.
Main features: tinned or plain copper conductor depending on supplier; solar-grade insulation and sheath; Red sheath for polarity identification; supplied per running metre.
Typical applications: solar panel strings; PV combiner box wiring; DC isolator feeds; inverter DC inputs.
Installation environments: rooftop solar arrays; outdoor PV cable routes; conduit or tray systems; solar plant rooms.
Benefits: UV resistant when supplier-certified; designed for PV DC circuits; clear polarity identification; common solar installation cable.
Maintenance considerations: Inspect for UV damage, abrasion, loose connectors and water ingress during solar system maintenance..
Safety notes: Use correct DC-rated protection, connectors and polarity practices; isolate PV circuits before working. Current-carrying capacity depends on installation method, ambient temperature, grouping, protection device selection and the applicable wiring code.
Sold per running metre.
