AKA a contactor - electrically controlled switching device. Could be used to control almost any load: lighting, motors, AC condensers, water heaters, etc.
I did not try to follow the wiring and there was no directory in the panel.
no special loads in the house which has been converted to a chiropractic office. Now AC, only one window unit, gas not electric water heaters, no motors, nothing special.
I intend to refer them to a qualified electrician for review and comments on this as well as some other concerns on the FPE panel, corrosion, double taps etc.
Still welcome any other comments on this device.
