Connection to the AC terminal block
For all models, connection to the AC terminal block 17 is made by
pulling conductors through a raceway connected to the AC conduit
knockout 16.
Remove the threaded plastic plug from the AC conduit knockout 16
and replace with a conduit hub sized to t the required wiring and
raceway. Pull the circuit conductors through the conduit opening
and connect the necessary conductors.
Terminal blocks are rated for operation to 90°C and accept wire size in the range
of 8 AWG - 4 AWG solid or with type B or type C standing (19 strands maximum).
For conductors with ner stranding, a suitable UL listed wire ferrule must be used.
The TRIO is intended to be connected to a four wire WYE grid; connect Neutral, L1, L2, L3,
and EGC conductors.
