King Innovation 95110 3-Port Aluminum Copper (10-Pack) Wire Connector, Purple

Easy to use and install, especially to manufacturers recommendations. Be careful not to loosen screws too much or else they're hard to get back in. otherwise, great product and provides safey and increase peace of mind. No more mixing / heating of copper nor aluminum wiring!

If you’re reading this, I’m pretty sure you are a handyman doing your own home. In our resort. A lot of the homes were built with aluminum wiring. Apparently if you sell, some home inspectors are insisting on this modification. Hiring someone to do it costs $3000 plus the cost of materials, so I thought I’d do this at my leisure.These items are a little bulky, and if you don’t have the large capacity boxes, I suspect they won’t fit. A typical receptacle will require 3 of the three joint terminals. If a particular box has an extra wire coming in, then you need more of these terminal boxes. Luckly for me, the home was built with the larger boxes. If you have the smaller metal boxes which are typically nailed to the stud, you have a couple options. You might be able to reach inside the box with a side cutter, grip the nail and pry it out (repeating this several times to remove the nail). Another option is to use an oscillating saw with a blade capable of cutting nails and cut between the stud and box. No danger of cutting electrical wires. It’s easy to install replacement boxes, and they come in different capacities, so be sure to buy the large one. Box extenders are another option, but they would probably look a little hooky, unless used in the garage.As far as the quality of these items, they have been good. The instructions are specifying 10 in-lbs torque on the aluminum wire and 15 in-lbs for the copper. I bought a special torque wrench screwdriver for this. I’d recommend you wear a glove on the hand you are holding this wire connector, in case you slip with the screwdriver, as you have to push pretty hard to be sure the screwdriver stays engaged.

Worked great for connecting three wires versus twisting and wire nutting. They are a little larger than they appear in the picture. But plenty of room in a junction box for two.Used the Torque screw driver. Got them good and tight. Much cheaper here than at the big box store.

There are 4 options for aluminum to copper remediation in older homes1) Completely rewire the house ($$$ and destruction)2) Purple wire nuts (similar price to these, and reports of them melting - although I suspect many are installed incorrectly in those cases)3) Copp-alum (Need extremely expensive tools and also expensive)4) Alumiconn (these, more fool proof than wire nuts)Given the limited options homeowners have, what can you do. These are supposed to be a lifetime fix and they are easy albeit tedious to install. Get the torque screwdriver and torque to appropriate specs, 15in lb for all copper, 10in lb for 12 gauge aluminum 15 for 10 gauge.I have gripes with these but what can you do, like I said there’s no other realistic option for most homeowners- These are stupidly expensive for what they are (patent maybe?)- The screws pretty much strip out at 15 in lb, they are also flat head which is just more annoying to get the bit in.These can be DIY’d easily, they are pretty fool proof by design so they’re hard to mess up. You need at least 3 per device, so packing them tends to be the hardest part sometimes.

price is quite high, seems about double what it could be?

I have been an electrician and contractor for over 35 years. These are the safest and easiest to use and most dependable connector for aluminum wiring applications today. They are a bit bulky but with careful use can be applied to most situations. If necessary replace an undersized j-box w a new roomier plastic box. It is worth the trouble. I would like to see the price go down a bit because it discourages these being used by low income people and they are the most vulnerable to losing homes and lives from aluminum wiring. This device accomplishes "pigtailing" rapidly and reliably.

I have an older home that unfortunately has aluminum wiring. I hate the purple wire nuts and I'm not spending the money to set myself to install bonding rings. Enter these GEMS, they are a little pricey , but compared to the tools needed for bonding rings, they will be cheaper in the long run. They will also allow future expansion if needed.

After trying and not liking the 'Twister' aluminum to copper wire nuts, I found this product. It's fantastic, much better than the Twisters. It does require a torque screwdriver to ensure you get the screws set exactly right, but it's well worth it and feels very solid in the end.

Terrific if not a bit expensive fix to my aluminum wire connections thru out my house. I was able to pigtail all my hundred plus connections myself and now feel confident my fire threat is dramatically reduced and my wiring would pass any inspection.

Had to order these after finding some aluminum wiring while painting our kitchen cabinets. These were only a few dollars more than a 2 pack at my local hardware store, which only had a single 2 pack, and I needed 4.

This item is the answer in any case where you have a predominantly aluminum-wired house and want to join Al/Cu conductors - for example if you want to come up to code by installing ground fault detecting sockets in washrooms (you can't get them for aluminum wiring direct). I had to open and fix a junction box where an Al/Cu connection had been done with a twist connect and had heated and open-circuited.

If used as directed, the product works as described. It needs to be held properly to avoid deformity to the plastic cover. Gloves can do the trick.
