The Major Tech PCT-224B is a 2.5mm2 four pole interjoining connector block, supplied in a jar of 25. The PCT-224B uses a screwless clamping terminal, so a stripped conductor pushes home and is held without a screwdriver, then releases for reuse. It is rated 450V and 32A with 4kV voltage resistance, and measures 23.10 by 39.30 by 14.30mm.
A screw terminal is only as sound as the last person to tighten it. A screw relaxed by vibration or thermal cycling becomes the loose joint that arcs behind a fitting years afterwards. The PCT-224B applies consistent clamping pressure to every conductor with no screw requiring verification, across four poles rated 450V and 32A.
Stripping to 11 to 12mm and pushing the conductor home consumes seconds against tightening a screw terminal on every core. The connector releases and reuses, so a maintenance alteration does not consume a fresh block. A jar of 25 keeps the vehicle stocked, and the compact 23mm by 39mm body occupies enclosures where a terminal strip will not fit.
The PCT-224B is rated for conductors to 2.5mm2 at 450V and 32A, so larger conductors and higher ratings need a different connector. Strip length matters: under-stripping leaves insulation in the clamp, and over-stripping leaves bare copper outside the housing. A connector block is not an enclosure, so the joint still requires a box or fitting around it, and installation is work for a licensed electrician.
