SHPELEC® Electrical Grey Twin and Earth 6242Y Cable 4mm Mains Socket Ring (4mm, 20m)

BASEC Approved 6242Y (6242YH) twin and earth cable made to BS 6004 — two stranded plain-copper 4mm² cores (brown / blue), 1.5mm² bare copper earth (fit green/yellow sleeving), grey PVC sheath, 300/500V. A commonly used UK size for higher-load radial, immersion-heater and selected cooker circuits. Circuit design, protective-device selection and installation must comply with BS 7671 and be completed by a competent person. Rated up to 37A clipped direct (BS 7671 reference method C). Actual capacity depends on installation method, grouping, insulation and run length — always check before sizing a circuit. Stranded fixed-wiring T&E is deliberately stiff: it dresses into clips and trunking and stays put once terminated. It is not a flex — for appliance leads use flexible cable. Cut fresh from the reel: lengths from 1m to 50m on this listing — pick your length above. Longer cuts work out cheaper per metre. For fixed indoor wiring.
