CPBF Series Solar Pass Through Boxes

CPBF Series Solar Pass Through Boxes are used in residential applications to provide a low profile, cost-effective way to group input wires/circuits from several arrays and/or solar panels and transition from solar (PV) cable to regular building wire.  The Pass Through Box was designed for PV applications where overcurrent protection is not necessary due to the low power rating of the PV string.
