Key item features

  • Durable Construction: Features toughened nylon housing and solid brass blades for insulation, preventing energization of non-current carrying parts and ensuring excellent conductivity without cracking in high-abuse applications.
  • Secure Connection: Designed with a tight locking mechanism to prevent the plug from vibrating loose and falling out, complemented by an internal cord clamp for secure wire connections.
  • Enhanced Safety: Each wire slides into a separate tube and is tightened to prevent shorting or stray strands, while a flexible rubber dust seal protects the wiring chamber from moisture and contaminants.
  • Effortless Installation: Ergonomic fluted body with a radial grip ridge aids in gripping, turning, and pulling, with alignment features for easy assembly and grip screws installed from the same side for convenient tightening.
  • Broad Utility: Widely applicable for generators, temporary power solutions, transfer switches, welding equipment, RVs, trailers, and camper welding equipment.
  • Industrial Performance: Built for severe industrial settings, combining quality materials with superior production standards for unparalleled flexibility and dependability.

30 amp 4 wire female plug

Have not tried it yet. Can't give honest review until I wire it to my cord and hook it up with a load under it.
