EZ Solar Rooftop PV J-Box (Asphalt Shingle)
The JB-1.2 is a flashed rooftop junction box for asphalt shingle roofs. Use it as the transition point between your rooftop module conductors and a conduit run heading to the inverter. The polycarbonate box mounts under the shingle with an integrated flashing skirt, so the roof penetration ends up under the next course of shingles and stays watertight. Rated 1000 VDC, 80 A, with a wire range of 14 AWG to 6 AWG. Type 3R enclosure, fits roof slopes from 2.5:12 to 12:12. One inch is the max conduit fitting size on both the side wall and the floor pass-through, which covers EMT, liquidtight, and most flex sizes you'd run on a residential array. Listed to UL1741 and CSA C22.2 No. 290. Operating range from -35°C to +75°C, which covers Gulf coast attic conditions year-round. Worth knowing: EZ Solar has discontinued the JB-1.2 and replaced it with the JB-F.100. The JB-1.2 still works fine on asphalt shingle and matches existing inventory, but for new designs going forward, the JB-F.100 is the newer part to spec.
