Hi have a project that is going to be lasting a few years and on a electrical meter the company are looking for a minimum of 3nm on the cennection terminal screws the problem is that this can get repetitive so does anyone know of a 1000v tool

A few people are finding the strain on there body's from using a draper torque screwdriver that is 1000v rated so I'm trying to see if there is a geared multiplier of same or a cordless approach that would have the same rating and be able to tighten the terminal screws to 3nm
