Over the years, Hendrix has maintained that porcelain insulators (and porcelain spacers) should not be used with covered conductor. This is due to the dielectric incompatibility between the two ...

Fine tuning: a new theoretical framework for controlling a system’s properties using laser beams has been developed. (Courtesy: iStock/Swillklitch) Laser light could turn a normally insulating ...

Note: This article is based on the 2011 NEC. Overcurrent exists when current exceeds the rating of equipment or the ampacity of a conductor. This can be due to an overload, short circuit, or ground ...

How you should treat the neutral conductor depends on your system design. Neutral conductors must be grounded to prevent inadvertent potentials on conductive surfaces of equipment, enclosures and ...
