Description

SSTB Series of Solar Transition Pass-through Boxes provide a quick, simple, and easy wiring transition between a micro-inverter trunk cable and standard stranded wire. All connections can be made using only a single #2 flathead screwdriver. This eliminates the need for any wire nuts or crimp type connectors. The included shorting bar assembles that are included enable combinations of 2 strings to be made, eliminating the need panel Y-connectors, or additional connector boxes. 3-hole cable glands are included by not installed. Enclosure holes must be drilled in the field. This is done so that you have the option to use conduit fittings for wire entry and exit rather than the cable glands.
