General note: On NEMA size 3 and 4 starters if selecting factory installed and wired operator devices (push buttons, selector switches, and/or pilot lights) then control circuit fusing, a control power transformer, or 120 V separate sourced control is required when the protective device is rated greater than 100 amps.
