10 Pcs Conductor Compact Connectors Lever Wire Nut Electrical Connectors for 2 Circuit Inline Splices 28-12 AWG

Easy to install and held wires well.

These little gems work great for under the table connections for model railroading! No need to crimp or solder with other tools. The connectors saved time and my back

I've had a chance to use these on a couple of low-voltage applications where I had a two-wire splice connection between a power source/transformer and a device that I didn't want to be permanent and they work well. The clamps are very strong and hold the wire firmly; even very thin 20 gauge wires.

Just like the expensive ones from the electrical supply house.

Inspired by Peter F, I took one of these apart to get good photos of the connector "guts". The build quality is excellent with tight tolerances, which is why it took so long to get one apart without destroying it. There is a healthy copper bar in the wire contact area, which you can technically get out, but not when it's in the plastic housing. The bottom molding has a CE stamp, but nothing from UL. I agree with Peter's observation that if you use 14 AWG or larger wire, then you should have no problems with the voltage creep distance over the internal partitions.I wanted to use this at 277 VAC, which will be fine. I find that a lot of 277 VAC UL products use relays stamped 250 VAC; reading their data sheets they are really 300 VAC, but since UL only have a 250 VAC and 600 VAC standard, they rated them lower. IEC has a 300 VAC standard, so Lutron and Crestron get their UL testing done (and pass) with 250 VAC labelled relays. Anyway, it's just something to be aware of.I wouldn't hesitate to use this at 277 VAC with 12 AWG wire, but if they want to try for UL, then they'll need to change their minimum wire size from 0.08 mm2 (18 AWG) to 14 AWG or 12 AWG (2.5 mm2). These are nice and clean for a 3-conductor splice where you want to be able to disconnect in the future, say versus a butt splice.

I initially purchased this lever wire nut because I had an application where a bracket to hold the wire nut was helpful. These did not disappoint. The bracket does solidly hold the lever wire nut in place.These lever wire nuts seem to be quality constructed and grab the conductor making a reliable connection. Once the lever is closed, wires cannot be removed (unless you release the lever). It grabs wires very solidly and makes a reliable connection. I would trust these lever wire nuts to join wires for long term service.The only CON for this product is that the levers are NOT color coded. If you read the description carefully, you'll see that these lever wire nuts are configured for TWO inline circuits. These lever wire nuts do NOT tie all four conductors together. Each of two inline circuits are tied together. Because all levers are orange, you might believe that you can connect 4 wires together as you might with tradtional wire nuts, but this is NOT true. What you have are two separate circuits inside this wire nut, so you could connect together a pair of two-wire cables.Other that this one CON, these are very good wire nuts that when deployed, should last FOREVER. I recommend this product.

Good value for the money

I got this to splice jumper clamps on my battery charger which came with some weird ass connector that was a pain to put on and take off.Now I have normal, standard jumper cable clips to connect my charger.Very solid, meet all the local electrical codes, quick and easy. Just cut the wire, strip off 3/4 inch, insert and clamp down. Done. Not worried about stress or pulling out.I used one like this with 3 slots to add a new outlet to an existing line that only had a couple inches of play, so didn't have room or slack in the wire to use wire nuts to splice in a new wire.So cut original wire (one black, 1 white, 1 green).Need 3 of these splicers, each with 3 inserts.Inside an electrical box (I used a thin / flat one).One block for all the black wires:- Put original black wire source into slot 1 & clamp down. Put original other end of same black wire in 2nd slot and clamp down, add 3rd black wire for new outlet into 3rd slot and clamp down. Now all black wires are bound together.- Do same for all 3 white wires (all 3 in one three-slot junction box)- Do same for all 3 green / ground wires.Presto, instant new wire to run to new outlet I was installing in ceiling of porch for camera.
