Normally it’s 1.7N isn’t it? Only 2.1 or higher for main switch you don’t need torque settings to know the correct torque I don’t think aslong as you understand the recommendationsI don't know how these manufacturers calibrate their torque screwdrivers, but mine was so far out it could not be tightened to 2.1N required by Hager without bending the Din rail the RCBO was fixed too, anyone want to buy a full set of Armeg drivers?

Difficult area but again like I said it all boils down to experience and knowledgeNormally it’s 1.7N isn’t it? Only 2.1 or higher for main switch you don’t need torque settings to know the correct torque I don’t think aslong as you understand the recommendations
