What this barrier strip handles — and what it doesn't
The TE Connectivity 1546310-6 is a 6-circuit Buchanan barrier strip rated 30A at 300V. A 30A strip accepting 10 AWG means it's sized for a power distribution block in a panel — not a signal-level terminal. The 0.563" (14.30mm) pitch gives enough spacing between circuits to land a 10 AWG ring terminal without crowding the adjacent screw. Dual-wall barrier (2 Wall) and an integral flange are included. The dual wall isolates adjacent terminals from each other and from the panel face; the flange provides a mounting ear so the strip bolts to a chassis or panel rather than floating on the wires. The closed bottom means the screw terminals are accessible from the top only — no through-hole access for a back-side nut. Insulation is black polybutylene terephthalate (PBT) rated UL94 V-0, so the strip is accepted inside equipment enclosures without an additional flame shield.
Wiring and termination — what lands on the screw
Top termination is screws; the terminal screw is steel with a nickel finish. The bottom is closed — no solder lug or PC tail. This is a panel-mount barrier strip: you land the wire under the screw head, torque it down, and the closed bottom keeps the screw from pushing through the back of the block. 12 wire entries total (2 rows of 6), so each circuit accepts one wire per row. The 10-22 AWG range covers stranded building wire down to control wiring. At 30A the strip is running near its thermal limit with 10 AWG.
