It is a panel-mount, screw-termination block rated 20A per circuit at 300V, with a dual-wall (2 Wall) barrier design that isolates adjacent terminals to prevent accidental shorting between wires. ## Sizing the Wire and the Connection The 20A per-circuit rating is the headline current at the terminal block level — every amp makes heat, and the dual-wall barrier helps manage creepage between adjacent circuits at that current. The wire range of 12-22 AWG covers the common power and signal wiring sizes: 12 AWG for the main feed at the full 20A, 14-16 AWG for branch circuits, and 18-22 AWG for control wiring. The top termination uses steel screws with a nickel finish, which resists corrosion in panel environments. The bottom termination is closed, meaning the screw clamp is the only wire entry point — no through-hole or solder tail below the barrier. ## Mounting and Layout for the Panel This block mounts to a chassis or panel via its flanges — the two mounting ears at each end accept screws for a secure, permanent installation. The 0.374\" (9.50mm) pitch gives enough space for 12 AWG wire and a screwdriver for termination without crowding adjacent terminals. With 16 wire entries (8 circuits × 2 rows), the dual-row layout doubles the density of a single-row block of the same circuit count, which matters when panel space is tight. The black thermoplastic housing provides visual contrast against a metal panel for quick identification.","metaTitle":"TE Connectivity 1546306-8 Barrier Strip, 8 Circuits, 20A","metaDescription":"TE Connectivity Buchanan 1546306-8 barrier strip, 8 circuits, 0.374\" pitch, 20A, 300V, UL94 V-0.
