2. Wiring Connection Diagrams

Figures 1-5 show the electrical relationship between TransTrack and these five basic service configurations: Single-phase,
2-wire, Split-phase, 3-wire; Three-phase, 4-wire WYE, Three-phase, 3-wire DELTA and Three-phase, 4-wire high-leg DELTA.

Connections to the SPD are clearly identified. Connections are made via pigtail leads supplied with the unit. For 3 phase
units phases A, B and C are black wires, which are marked "PHASE A", "PHASE B" and "PHASE C" respectively. For split
phase units, the phase connections are marked "PHASE A" and "PHASE B". For single phase units, the phase connection
is marked "PHASE A". The neutral is a white wire and the ground is a green/yellow wire.
