The selective entry system allows cables to enter from any of multiple pre-marked knock-out points around the perimeter, giving flexibility in positioning and routing cables without having to pre-determine entry angles before installation.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential, commercial and light industrial installations where multiple cables need to be joined or branched in ceiling voids, under floors, or behind stud walls, the junction box sits 26mm deep when surface-mounted or can be recessed into cavity walls. The IP20 rating makes it suitable for dry indoor locations but not for damp zones like bathrooms or outdoor use. The six terminals accept cables of standard domestic gauge and are secured with brass screws.\u003c\/p\u003e\n\u003cp\u003eThe thermoset resin casing resists impact better than standard thermoplastic and holds its shape under heat from sustained current draw, making it a more durable choice for permanent installations in areas where the junction box might be knocked during maintenance or building work. The black finish makes the box less visible when surface-mounted on dark ceilings or walls. Certified to BS EN 60670 and backed by a 25-year warranty.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e89 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e26 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eThermoset resin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_2002447_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat cable sizes does the junction box accept?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe six terminals accept standard domestic cable gauges typically used in UK 230V circuits rated up to 20A, including 2.5mm² twin-and-earth cable.
