4-Circuit Barrier Block for Panel-to-Board Power Distribution
The TE Connectivity Buchanan 8PCV-04-006 is a 4-circuit barrier strip from the #8 series, designed for terminating individual field wires to a printed circuit board. It uses a 3-wall (tri) barrier construction with screws and captive plates on top for wire clamping, and PC pins on the bottom for soldering into a through-hole PCB. The 0.438" (11.12 mm) pitch gives enough spacing to handle the 30 A per-circuit rating without tracking between adjacent terminals — a common failure point on tighter-pitch power blocks.
Wire Range and Current — Matching the Conductor to the Load
The 8PCV-04-006 accepts wire from 10 AWG down to 18 AWG. At 30 A, the terminal is sized for a 10 AWG copper conductor running at its full ampacity — anything smaller derates the usable current below the block's rating. The screw with captive plate bears directly on the conductor, so stranded wire needs a ferrule if the installation sees vibration; the zinc-plated steel screw resists corrosion in industrial cabinet environments. The 600 V rating is the maximum voltage between adjacent circuits or to ground, typical for motor control panels and power distribution blocks inside a UL 508A enclosure.
Mounting and Termination — Through-Hole PC Pins
This is a permanent connection; the block is not designed for repeated removal from the board.
