{"product_id":"60a-3-terminal-junction-box-brown","title":"60A 3-Terminal Junction Box - Brown","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThe Knightsbridge 60A junction box is a 3-terminal enclosed wiring connector rated to 60A on 230V mains, housed in a brown thermoset resin casing with a hinged lid. Three brass terminal blocks inside accept cables up to 25mm² cross-section, with built-in cable strain reliefs to prevent mechanical stress on the connections. The box measures 147mm long by 90mm wide with a 40mm projection when wall-mounted.\u003c\/p\u003e\n\u003cp\u003eDesigned for permanent mains wiring in residential, commercial and agricultural installations, the junction box is typically used to split circuits, extend cable runs or connect fixed appliances such as cookers, shower units and immersion heaters where the load does not exceed 60A. The brown finish allows it to blend into timber structures, outbuildings and service cupboards. The IP20 rating means it's suitable for dry indoor locations but not exposed outdoor positions or bathroom zones.\u003c\/p\u003e\n\u003cp\u003eThe thermoset resin construction resists impact and heat better than thermoplastic enclosures, making it appropriate for higher-load circuits where terminal temperatures can rise under sustained current draw. The hinged lid secures with two screws and provides access to the terminal blocks for inspection and re-termination without removing the box from the wall. Certified to BS EN 60670, the junction box carries a 25-year warranty from Knightsbridge.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e147 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e90 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e40 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\u003eBrown\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\/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_2003181_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_1150518.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat cable size does it accept?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe junction box accepts cables up to 25mm² cross-section across all three terminals. This covers most domestic and light commercial fixed wiring circuits rated to 60A.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it be used outdoors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The IP20 rating means the box is suitable for dry indoor locations only. For outdoor or damp environments you would need a junction box with a minimum IP rating of IP44 or higher.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between thermoset and thermoplastic?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThermoset resin is heat-cured during manufacture and cannot be re-melted, making it more resistant to sustained heat from high-current circuits. Thermoplastic softens at lower temperatures, so thermoset enclosures are preferred for higher-rated connections like 60A circuits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is it fixed to the wall?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe base of the junction box has mounting holes for screws. Fix the base to a solid wall or joist, run cables through the knockouts, terminate at the brass blocks, then secure the hinged lid with the two cover screws.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293981401355,"sku":"SN8470B","price":4.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/159048_fb41b725-0d5f-4e7d-ac24-2e121122e7bf.jpg?v=1714667079","url":"https:\/\/niori.co.uk\/products\/60a-3-terminal-junction-box-brown","provider":"Niori","version":"1.0","type":"link"}
