Messer's D Galley & M Rogers founded the company in 1975 manufacturing switchgear for the National Coal Board from premises at Thorp Arch, Wetherby. By 1990 the company was well established with a 2 Million turnover, Mr Galley had reached retirement and Mr C Houseman & Mr S Shepherd took over as directors in 1992.
Changes throughout the 1990's in markets, with demise of the Coal Industry, brought about a redesign of the switchboards, still keeping the high specification but developing a modular concept, ensured easier manufacturing techniques & faster production methods. 1996 brought about a change of premises with relocation to Sherburn in a purpose built factory increasing office & engineering capacity, to cope with the continued successful growth.

Simply, every switchboard must have a 3 phase Short Circuit Withstand for the complete assembly and a PE certificate typically 60% of the 3 phase fault level. This test assuring that the fault withstand capability of the product is a statement of operation without failure to either personnel or equipment up to the detailed fault level, and therefore suitable after for further service, .
However important it's commonly overlooked because it forms no part BS EN 61439:2011. Switching is obviously the name of the game and this is an item we at GR Electrical notice come up over and over again, particularly when the price is involved.
Modern day systems and the greater implementation of increasingly compact systems and in turn optimisations of components put increasing pressure on switchgear manufacturers to ensure that their temperature rise within their panels is within the maximum allowances, this to ensure the system is a fully rated system and minimise the risk of failure due to exceeding temperatures.
