Sintron NEMA L6-30P 30 Amp Twist Lock Plug, 250 Volt, 2 Pole, 3 Wire, ETL Listed, Male Plug Locking Connector for Welder Generator Transfer Switches Power Tool, Industrial Grade, Grounding 7500 Watts

Installed on my welder to match the socker i have on the cart. Works great.

I’m using this for a generator hookup and it is ideally perfect for my use. The plastic was thicker then I expected and built quality was good, not as good as the premium one over twice the cost, but great for my need. I’m using a generator producing just under 40 amps, so my cable is using 8 AWG conductors and the cable is a perfect fit, if you were using 50 amps with SOOW 6 AWG 4 conductor cord would be a little too big and I’d recommend spending the extra for the very high quality plugs with the triple finger grips and compression screws on the wire contacts. This plug will also work fine for the range indoor cords with 2 x 6 AWG and 2 x 8 AWG with a thin jacket, just the indoor/outdoor SOOW 6 AWG cord is way too thick and would require grinding out the hole for the cable to a larger size.

This is a very nice product--I'm very pleased with it. The directions are lacking, however, creating a potential installation/usage problem. The removable 2 piece grommet at the end should be noted in the documentation--how many pieces should you use with what gauge wire? You can't have it too tight (it won't seal) nor too loose (doesn't provide strain relief). A trimming guide would also be useful to cut and bend the heavy gauge wire correctly the first time....6AWG is tough to work with in a tight space.

Use the brass blade width as a strip gauge (strip that much insulation off). Cut the 2 lower wires (shown here white & black) shorter than the upper one by just a bit more than the blade width. The connector screws were too tight to remove when holding the blades in standard pliers, or with the blades inserted in the housing, but a vice made it pretty easy, so a big crescent wrench, vice-grips, or channel-locks might also work, especially if you have a second pair of hands available. The cable clamp at the bottom has 2 different-depth slots on each side, for a total of 3 different cable thicknesses. On the thinnest (outer) setting it clamped okay on my 14 gauge cord.

As you can see the item I received is the exact mirror image of the actual part. No way to plug in the 6-50p Plug as the fat prong is on the wrong side!! They got it right on the image for the website, but actually making the part it is backwards!! (Sorry right image is dark, but that is the computer screen showing the actual part I ordered)!!! UPDATE: I learned something new there is another part that is the mirror image of 6-50R namely 5-50R. Seller reached out to me and said that some of them got mis-labelled/mis-boxed in the warehouse (As the asin # was correct on the first one. I always check that first when wrong item received.). I had already returned the bad one, so I went ahead and ordered a new one. It arrived yesterday and is the correct one. The quality of it is actually much better than the more expensive one that I had ordered to get the welder up and running. It is structurally much stronger and has better contacts. I will be returning the more expensive one. Thank you to the seller for reaching out and letting me know about the issue and that there was an actual mirror image product.

Gets the job done.

Plug is fine, but the screw holes for attaching to a cover plate are slightly bigger than standard.

This thing is solid and well made. The terminals on the inside of the plug have Phillips style screws and a mounting plate so you can make the connections. I used spade terminals to make the install a little cleaner and the connections more secure. Well priced plug.

What else is to say. It's a plug.

C'est exactement ce que j'avais commandé.

Had my new glass cooktop wired, plugged in, and working within 30 mins.

très bien

Qualité à bon prix
