Recognized as an IEEE American National Standard C62.41-1991 (Revision of IEEE C62.41-1980) IEEE Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits Sponsor surge-protectiveDevicesCo”ittee of the IEEE Power E h g h m w gSociety m Approved February 25,1991 co IEEXStandardSBOard p. Approved September 6,1991 American National StandardsInstitute ou Abstract: A practical basis is provided for the selection of voltage and current tests to be applied in evaluating the surge withstand capability of equipment connected t o utility power circuits, primar- r ily in residential, commercial, and light industrial applications. The recommended practice cov- ng ers the origin of surge voltages, rate of occurrence and voltage levels in unprotected circuits, waveshapes of representative surge voltages, energy, and source and impedance. Three locations categories are defined according t o their relative position from the building service entrance. For su each category, representative
