PHASE-TRIP NO. 1 BOARD

The second board from the bottom is the phase-trip No. 1
board (Figure 11). It has three full-wave diode sets, one for
each phase, along with a loading resistor for each phase.
This board also has the beginning circuits for the minimum
trip function.

PHASE-TRIP NO. 2 BOARD

The phase-trip No. 2 board (Figure 12) carries the remaining cir-
cuits for minimum-trip and the wave-shaping circuits for the timing
plugs. There are two tabs on the phase-trip No. 2 board for the
Form 3 and 3A control. one tab is labeled minimum-trip (MIN.
TRIP)* and is battery plus for normal line currents and switches to
battery minus for fault currents; the second tab marked (DIR.
BLOCK)* is an inactive tab at this time.

* In early Form 3 boards, these tabs may not be labeled.

GROUND-TRIP NO. 1 AND NO. 2 BOARDS

The next two boards up, ground-trip No. 1 and No. 2 (Figures 13
and 14), are like the corresponding phase-trip boards, except that
the ground-trip No. 1 board has only a single input diode bridge for
ground current. These boards carry almost the same parts and
same configurations as the corresponding phase boards.
