Electricians Ipswich were working with SECELEC to deliver a new metal conduit and trunking electrical system to BS7671. The location was Huworth House, Stables, Fordham Street, Newmarket for prestigious horse trainer. The original electrical system was in a very bad way. It was a metal conduit system with vulcanised India rubber single core insulated cables. The cables were in very bad way. We estimated the installation date was circa 1940’s-50’s. So they were well past the 25 years most electrical systems designed lifespans. Brittle insulation and the conduit was very weak and rusty. We knocked out large holes between each stable and put in 3×3 metal trunking which went around the U shaped stables. This was difficult as the walls were not square so we had to pack out behind the rear of the trunking so that it remained square throughout the installation. In each stable we had to put a flourescent light fitting 58w Ip65 and an infra red lamp which was a horse heater 250w on a pendant. These were supplied through metal galvanised conduit 20mm and controlled through Lewden rotary switches. There was also a farriers workshop, rest room and toilet facilities which were installed using the same system. The incomer cable was 35mm 3 core and it went into a 100amp isolator before stepping down into metal consumer units which has it’s own individual RCD protection for each circuit. Two Consumer Units were used at two different locations within the site one in the middle of the block and the other by the farriers room.
