King Innovation 95015 AlumiConn Wire Connector, 10 pk, Purple, Count

Fantastic product which is easy to install so insurance companies will be placated. In my area there are thousands of homes with aluminum wiring that were built with quality electricians and proper engineering so they are not burning down unless the untrained person makes changes. Problem comes in when people start making changes to the work which is what this product is perfect for. Now homeowners can work with their aluminum wiring and as long as they follow the simple instructions they will not have any issues.I had no problems with these fitting into the boxes even with four or more needed because as mentioned above houses around here were built right and the boxes were large enough so the aluminum wire was not bent to harshly causing an overheat issue.On the other side tho an aluminum rated device properly torqued and pasted is the same install. So the whole training thing seems to be the issue. This is the reason why I gave three stars for the value for the money. As soon as "regular Joes" start improperly using these and the house fires start up insurance companies will require a different product that has no track record (like 50 years).

Great product. Buy the King Innovation version, not the other product listed.

Finally! A rational, reasonable, affordable alternative for taming the aluminum wire menace.The only 100% solution is to rewire your house with copper. Meanwhile, the rest of us live in the real world.The COPALUM crimp system has been around for years, but is still very expensive and it can be a challenge to find a company-trained and -certified electrician to do the job.Enter AlumiConn: basically a little set-screw bus bar encased in a plastic box with the wire holes packed with antioxidant sealing grease. The connections are super secure, sealed, and the aluminum and copper never touch.If you do some research you'll find that the UL-approved installation requires an inch-pound torque screwdriver. I did a destructive test and found that the #10 aluminum and #12 copper wires were nicely squished under the set screw when following the company's instructions without the expensive screwdriver. After decades of tightening fasteners and terminals, I have confidence in these things.I've cleared out one dubious pigtail done by the previous owner and I'm looking forward to installing AlumiConns on every outlet and switch in our house.Pros: Quality construction and materials, not nearly as bulky as you'd expect, in-line wire arrangement makes box stuffing easierCons: Only 3 terminals, big enough to require larger remodel boxes if you're working with devices like dimmers

I have an older rental house with aluminum wiring. These connectors seem much more secure and reliable than the purple twist ons. Be sure to get a torque screwdriver to properly install these. The wiring I encountered was 12ga so I had to back out the lugs almost all the way to get the wires properly seated. I like that they have two-wire versions for tight electrical boxes as these connectors are rather large. Also, I found some shallow GFCI receptacles that helped free up space (Leviton GFTR1-3W).

I'm not an electrician, just a layman doing some electrical work in my home. I've done plenty before - under the guidance of electrician friends - so I know what I'm doing. But when it comes to aluminum wire, well, I don't. My research indicated this was the best product for connecting aluminum wire to aluminum wire, or aluminum wire to copper wire. Not much information was out there about connecting copper clad aluminum wire to copper wire, which is what I had to do. What did exist indicated that this would be the safest way to go, if not overkill.I only needed two of these, and was pleased to find them on Amazon for just a little change over the per each price when bought in a box of 100. I found the product easy to use and I'm satisfied that I've taken no chances with my house, my family and the safety of both.I don't know of another product like this. If you need connect aluminum wire to copper or aluminum, this is it. If you need to connect copper clad aluminum to well, anything else including itself, I think this is it, but that's not a documented fact.I will note that they came in a plastic bag. No labeling, no instructions. Perhaps the seller bought in bulk and sells them per each. All I know is they didn't appear to be labeled for per each sale. This didn't bother me, but please be aware that there are some torque guidelines the manufacturer recommends and without the documentation, you wouldn't know that nor what they are. I'm a perfectionist so even though I thought use of the product seemed pretty self-explanatory, I did a quick Google search and came up with the manufacturers website / instructions. Will your house burn down if you don't follow the recommended torque? I don't know, but the reason I bought these was to take no chances so I'm glad I sought out the instructions.I would certainly buy again or recommend to a friend.

Does a great job at not mixing aluminum with copper wire! Easy to use, just make sure not to loosen screws too much cause they easily fall out and then need to take time to reinstall them. cover stays closed when snapped. Wish they were a little cheaper but worth it to keep you and your family safe! And make sure to get torgue screwdriver to tighten down to manufacturer's recommendations!

Worked perfect for a water heater that had aluminum wiring to copper.

OK, so they are more figity than purple wire nuts, and they can be a little harder to squeeze into a box (or not, it depends), but these connectors isolate the wires in a stainless steel block so they Cu and Al never touch. No electrolysis causing resistance, and no loosening due to Al expansion. If you care about your results and safety, they are well worth the $$.
