STEP 4: PV Output Circuit Wiring Terminations in the Re-Combiner
The PV Output Circuit conductors terminate on tabs extending from the DC switch. The
tabs are factory-supplied with dual studs to maintain conductor alignment. Figure 5.3
illustrates the terminations and the sections below identify the relevant specifications.
Note that users must supply the Crimp Lug and Fasteners as defined.
