Review on 🔌 Legrand L630PCCV3 Industrial-Strength NEMA L6-30P Locking Plug – High Amp, IP20, 3-Wire, Black by Yung Kitamura

The plastic looks very solid and strong and the connector is secure. I also appreciate that the internal connectors are fully insulated with plastic walls, so there's no possibility of a short circuit through the wrong strand of the cable. The only thing I complain about is the threads on the screws. The threads bite right into the plastic (like a wood screw, as opposed to threading like a machine screw), so after enough screwing and loosening, the plastic will wear out and leave the screw with nothing to fasten, limiting reuse. - Ease of use of the plug.
