It carries a 15 A per-circuit rating at 300 V, with a 0.438\" (11.12 mm) pitch that spaces the terminals wide enough for 14-22 AWG wire without crowding the screwdriver. The dual-wall barrier (2 Wall) isolates adjacent terminals — a practical safeguard when you're landing field wiring and don't want a stray strand bridging circuits. Top termination uses screws with a captive plate — the plate stays under the screw head, so you don't lose a washer during installation. The bottom is closed, meaning the screw terminals are only accessible from the top side, which suits panel-mount layouts where the back of the block is against a metal surface. ## Six circuits, twelve wire entries — dual-feed per pole This block has 6 circuits but 12 wire entries — each circuit has two screw terminals. That means you can land an incoming feed and an outgoing load on the same barrier, or daisy-chain the power rail through the block without jumper strips. The two-row layout puts the terminals in two parallel rows, with the common bus bar connecting each pair internally. The 387800306 shares the same 0.438\" (11.12 mm) pitch, 15 A rating, 300 V rating, flange features, and dual-wall barrier as the 8-circuit 387800308 and the 10-circuit 387800310. The only difference is the circuit count — 6 circuits here versus 8 or 10 in the larger siblings.","metaTitle":"Molex Beau 38780 387800306, 6-Circuit Barrier Strip, 0.438\" Pitch, 15 A","metaDescription":"Molex Beau 38780 387800306 barrier block, 6 circuits, 2 rows, 0.438\" (11.12 mm) pitch, 15 A, 300 V.
