CONNECT TO A JUNCTION BOX OR AN ENPHASE Q AGGREGATOR  Connect the Enphase Q Cable into the Enphase Q Aggregator (See Figure 14).The Enphase Q Cable uses the following wiring color code. A ground lug is provided on the Q Aggregator for convenient PV module/rack/balance of system (BOS) grounding.  Refer to the wiring diagrams on Figure 15 for more information. Wire colors are listed in the following table. Figure 14.
