This is a great heavy-duty plug for L6-30 connections. I have wired this up to my well so that I can quickly and easily hook it up to a generator if the power goes out.

Also bought matching socket - for use with 5kw shop heater. Cheaper than local home centers, sometimes by a lot. Will use with 10-2 SOOW cord for quick disconnect to service heater. Same plug on my other shop heater, in service for 13 years without issue. Prefer to use name brands such as Leviton for the quality.

When choosing a system for deploying twist-lock connectors, the NEMA value is very critical. It just so happens that I run appliances both in my home and shop and in the field, connected to a genset. The new UL code says something about appliances using the two hot leads and the Neutral needing a four-prong plug and socket system, but in my case I use the third prong as the Grounded Conductor, or Neutral, and run an external frame ground with a secure, lugged and bolted cable to each appliance that cannot be unplugged, and that doesn't bond to the Neutral in the appliance.So when choosing the Twist-Lock setup of your choice, look at the NEMA code. The plug in this review is called an "L6-30P."This means the "L" refers to the system as Locking. The mating receptacle, whether it be in a wall or on a cord, willhave a NEMA code starting with the letter "L" as well.The letter "P" at the end means it is a cordset PLUG. (The male contrivance) This is important because you never want to end up with a "P" end that can be energized while disconnected.The "30" number means it is rated for thirty amperes. This is critical, now because if you discount the "L" and "P,"you can deduce the size and number of conductor pins. "6-30" means three metal contacts. Two are designated as live current carriers and the third is designated as a ground. In other words, a "6-30" anything will ONLY connect to another "6-30" something.As far as quality in this product, I happen to like the method of clamping the cordset on to the shell, and the method of capturing the bare conductors into the live body. The materials are strong and meant for industrial environments. This is not really a "convenience" cord connector, but it is recommended to you by someone who makes these cordsets up and uses them frequently.

A good, sturdy plug that I suspect will offer years of good service beyond the first piece of equipment that it is tied to. My only nit is that a soft rubber shell would be nice: this plug has a furled hard plastic barrel that is reminiscent of the old Nikkor lenses, though in plastic instead of metal, and on a shop plug instead of a lens. It's going to get coated in grease and oil in the shop, I'm afraid, and be difficult to grip well. But other than the material choice, the plug is well manufactured.

I have installed 2 of these Leviton plugs to finish off heavy machinery cords. Both installations look nicely finished. This type of 220 volt locking plug works well for fixed machinery as it never comes loose from the receptacle.

Leviton locking plugs are fantastic! I cut the cord ends of all my 220VAC equipment and replaced them with these plugs (20amp plugs for the 20amp machines and 30amp plugs for the 30amp machines). The twist lock feature keeps the plugs from coming loose at inopportune times, and I can also use them for ceiling mounted receptacles to keep the dangling cords from unplugging.The twist lock feature also keeps the prongs from bending as easily like normal plugs do. It also ensures a secure plug-in contact with no chance of shocking yourself in case of accidentally touching a prong while plugging-in or unplugging it.It is easy to install the wires and has very durable parts.It comes with two different size grips to accomodate different size cords. In a few wiring situations, I was able to mix-match the cord grips to get the perfect fit.These will outlast any normal style plug.

As described. This plug has the branded markings and came in the OEM box. It is half the price on amazon as at home depot and worked great.
