Switchboards and Panels
High legs. If a 4-wire, delta-connected, 3-phase (high-leg) system supplies a panelboard, the high-leg (or wild-leg) conductor, which operates at 208V to ground, must be terminated to the "B" phase of the panelboard. Prior to 1975, the high-leg conductor was terminated on the "C" phase of panelboards and switchboards.
