How to Size a MOV for Surge Protection | eHow Examine the electronics schematic and determine the working voltage of the circuit. For alternating current, or AC, divide the RMS, or root mean square, voltage by .707 to obtain a peak value. For example, dividing 110 volts AC by .707 gives 156 volts. Fo
