Wiring a 15-Circuit Power Distribution Point
The Molex Beau 38720 0387207515 is a 15-circuit barrier terminal block with a 0.375" (9.53mm) pitch, designed for through-hole PC pin termination. It accepts 12-22 AWG wire and secures each circuit with a screw and captive plate — no loose hardware to drop into a live panel. Rated 25A per circuit at 300V, this block handles motor feeds, heater loads, and DC distribution in industrial control cabinets.
Sizing the Board Footprint
The 0.375" (9.53mm) pitch gives each terminal pair enough spacing to land 12 AWG ring terminals or ferrules without crowding. The 15 circuits span roughly 5.6 inches of board edge — plan the keep-out zone for screwdriver clearance above the captive plates.
