Preparing for my DC homopolar experiment of a General Electric I-10 electromechanical watt hour meter from 1910.

When considering connecting an iron wire wrapped around the back of the cast-iron back piece (of the single phase, I-10, General Electric AC meter) to a large iron mass to enhance power output, it may be necessary to short out the connection from the meter to the inductive load in order to prevent all of the power of the load passing through the meter to prevent frying the meter because the meter may be acting as a mere signal generator while the load provides its own power.!

 

The cast-iron backpiece already adds iron mass to the unit in addition to the mass of the toroid inside the unit and thus is already intended to help the meter handle the generation of power for any loads in addition to the meter itself acting as a load. So connecting the cast iron backpiece to a iron mass via an iron wire merely adds more mass than what the backpiece already adds to the capability of the meter to handle any load larger than itself.
