Barrier strip for panel wiring — 8 circuits, screw termination
The flange on each end provides a mounting point for chassis or panel installation — the block bolts down, not just clips in. The closed bottom means the screw terminals are only accessible from the top; there is no pass-through or daisy-chain exit underneath, which keeps the wiring tidy against the panel surface.
Termination and wiring — screw top, closed bottom
Top termination uses steel screws with a zinc, clear chromate finish. The screw clamps down on the stripped wire end — no crimp terminal or ferrule required, though a ferrule helps keep stranded strands together. The bottom is closed, so each wire entry is a dead-end hole; the screw presses the conductor against the current-carrying bar inside the block. With 16 wire entries across 8 circuits (two per circuit), you can land two wires per position — useful for looping power to a downstream device without a separate splice. Wire range is 14-22 AWG. At 14 AWG the screw clamp has good bite; at 22 AWG the smaller conductor needs care to avoid overtightening and cutting strands. The terminal screw material is steel, so the threads hold up to repeated torquing in the field — the zinc clear chromate finish resists corrosion in indoor panel environments.
Position count comparison — 8 circuits vs 5 and 14
The 387600108 sits at 8 circuits in the Beau 38760 series. The 5-circuit sibling 387600105 shares the same 0.375" pitch, 15 A, 300 V rating, UL94 V-0 housing, and screw top / closed bottom construction — the only difference is the position count. At the other end, the 14-circuit 387600114 uses the same pitch and ratings but stretches the block length to fit the extra positions. The flange, mounting pattern, and wire gauge range are identical across the series, so swapping between them means adjusting the panel cutout length, not re-evaluating the electrical fit.
