Review on Leviton 2621 30-Amp, 250-Volt, NEMA L6-30P, 🔌 2P, 3W, Locking Plug, Industrial Grade, Grounding - Black/White by Bernard Her

NEMA is very important when selecting a system for deploying twist lock connectors. It just so happens that I use devices both at home and in the shop and in the field connected to a generator set. The new UL code says something about devices with two hot wires and a neutral wire that require a four-pin plug and socket system, but in my case I use the third pin as the ground wire or neutral and run the outer frame ground with a safety cable with spade lugs and Bolts for any non-separable device not connected to the neutral conductor in the device. So be sure to look out for the NEMA code when choosing your twist lock configuration of choice. The connector is called "L6-30P" in this test. So the "L” refers to the locking system. The junction box, whether in the wall or on a wire, also has a NEMA code that begins with the letter "L." The "P" at the end means it's a cable connector. (Male Apparatus) This is important because you never want to end with a "P" which may be live when disconnected. The number "30" means that it is rated for thirty amps. This is very important because if you omit "L" and "P" you can determine the size and number of conductor pins. "6-30" means three metal contacts. Two are marked as live current carriers and the third as ground. In other words, "6-30" something ONLY connects to another "6-30" something. Trapping bare conductors into a living body. The materials are durable and designed for industrial environments. It's not really a "handy" cable connector, but it was recommended to you by the person who makes and uses these cables frequently.
