Your cart is empty.King Innovation’s AlumiConn Aluminum to Copper Lug is approved by the Consumer Product Safety Commission (CPSC), UL, and numerous insurance companies as a safe method for aluminum wiring repair. Manufactured in Missouri, AlumiConn is a lug style connector with two separate ports to eliminate intermixing of conductors. It coats aluminum wires with a thin layer of silicone sealant to provide resistance from oxidation, and uses set screws to break up surface oxides and provide a secure mechanical connection. Avoid a complete re-wire by using AlumiConn, the most cost-effective aluminum wiring repair solution available.

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

I read that in the US for aluminum wire, copper pigtails using wire nuts was no longer code.AlumiConn connectors was one of the accepted remediation's. The screws in the AlumiConn have to be torqued as per manufacturers recommendations.Although more expensive than wire nuts you can't put a price on safety!

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).

Easiest way to upgrade aluminum wiring to copper based switches and stay in code...bit pricey but time has a value too.

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).

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!

These are brilliant. Ever try to wire a light fixture with tiny stranded aluminum wire normal gauge household copper wiring?? It’s difficult unless you are a pro electrician. And the wire connectors sold for aluminum to copper are too big for a small aluminum strand to household copper. These make the task simple,secure and much safer in my non expert opinion. Most people also don’t know that aluminum to copper connections require a antioxidant lubricant on both wires. These connectors already have it filled in the holes.Awesome product. They only improvement I see that could be made is the price!!! YIKES!! And the fact that you MUST torque the screws to 15 foot-lbs using a torque screwdriver. I had one. You would be amazed how much torque 15 foot lbs is. Great product. I gave it 5 stars but due to the price it’s really 4.5. But I would buy them again anyway

I wanted to copper pigtail an aluminum wired house and found that I was faced with very short wires in the junction boxes. I found the Alumiconn was easier to use than the wire nut variety, I was somewhat concerned about the size of the Alumiconn might be difficult to fit as a lot of the junction boxes had nails driven through the box. However with some planning on the wire management I found it was possible. Although the Alumiconn is the more expensive solution than purple wire nuts or the T&B ACS wire nuts, I believe having the wires terminated individually provides a superior connection.

The King connectors worked well. You need to know the amount of space available when using them as they are large. The items secured the aluminum wiring as designed, and I was able to eliminate the compatibility issues when connecting copper to aluminum.

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.

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
