    M‑2270B Application Guide Lightning Protection Lightning Protection It has been determined that transient voltages in excess of 1500 Vac rms can exist on the "ground" lead normally tied to TB1-8 on the printed circuit board. In the Tapchanger Controls, these voltages are suppressed by varistors which still permit the unit to pass a 1500 Vac Hi Pot test for one minute with a leakage current of approximately 15 mA, all terminals to ground.
