The Lister 12/2 puts out 100 foot lbs, so it wins over a gas engine on gen start up which goes to triple the HP load rating. This means that if you want to put a starting inducitive (motor) load across a generator, it had better be 3 times the electric motor’s rating. So a 4 HP motor attached to a load will need a 12 hp/ 9 KW genset. Gensets can be different unless they are connected to batteries direct, so start up should be decoupled and the batteries kicked in gradually if your gen is not over the load by three times. Twice is dicey.
After SWRDC sold the original factory site for redevelopment to specialist St. Modwen Properties , the residual engineering group announced its intention in March 2013 to relocate from Dursley. In Autumn 2013, the company fell into a third period of administration. Rescued quickly through a pre-packaged administration - which avoided the company's legal obligations to pay the required 250 redundancy packages, which were instead paid by the Government - the company's association with Dursley ended in April 2014, when assembly production moved to Hardwicke and the parts supply store to a former Royal Air Force hangar at Aston Down .
