LOAD CONNECTION (I): The basic interconnection between the BOP and the load are
shown in FIG. 3-5. The load wire size for the 2-wire connection shown should be as large
as practicable to keep the series resistance and inductance low. In addition, the load wire
pair should be tightly twisted, to reduce possible “pick-up” from stray magnetic fields. The
basic 2-wire connection is useful where the voltage drop in the load wires is of minor con-
sequence, as for example, operation into a constant load or in a constant current operating
mode.
