iPhone and iPad Software to Calculate Resistance and Voltage DropNeed to calculate the electrical resistance or voltage drop of a wire or cable? Wire Calc can do this, and more. Enter in the length of the wire (using English or Metric) units and the gauge, select the type of wire (...
Check the wires for a voltage drop of 3 percent or less. For small standby generators located close to the loads, this is not usually a problem. For units located farther away, where the required cable size is close to the full load current, it can affect operation. Use cable resistance ...
Foreign wall outlets may also fail NEC requirements for GFCI protection, which cuts power in the event of an electrical surge (it's worth consulting anelectrician about safer GFCI outlets in old homes, for this same reason). In fact, whether or not your preferred outlets meet legal standards,...
