AC Power Cord Specifications for a QFX3008-I Interconnect Device with Three-Phase
Wye Wiring Trays
286
Each three-phase AC wiring tray has a metal wiring compartment that contains the AC
terminal block and ground. There are two types of three-phase wiring trays: delta
(three-wire) and wye (four-wire). The delta AC terminal block consists of three input
