Customer Questions & Answers

Is the minimum gauge for AL really 12? Household wiring is 14 gauge. Does the connector support #14 AL wire?

Asked by: LittleDrummerBoy
Little known fact, 12 gauge aluminum is equivalent to 14 gauge copper. So no this connector does not support 14 gauge al wire but you also don't have that in your walls guaranteed. In fact 14 gauge aluminum is too small to even be rated to carry any load.

How do I fit the 2 or 3 port connector into an existing wall outlet box? It is already crowded in there. Does Kingston or a competitor make a smaller unit?
Asked by: Heraldic1
Hi Heraldic1- If you are having trouble fitting the AlumiConn connectors into the junction box, you could consider replacing with a deeper junction box. The AlumiConn lug-style connector is the only wire connector on the market approved by the Consumer Product Safety Commission and Insurance Companies as a permanent solution for aluminum wiring. If you have any questions, please feel free to contact us at

This was my first use of these connectors as I had used the purple slip-on style before. These appear much more secure and safer because the aluminum and copper wires never come into contact. While they take up more room in the box, I'll sleep better at night. I wouldn't use anything else from now on.

I immediately began to do research on how to make it safer without having to rewire the entire house (which would probably cost around 15-20k). I work for a law firm and have made close relationships with electrical experts during my time there, so I spoke with one of them regarding making aluminum wiring safer. I stumbled across the AlumiConn devices in the beginning of my research, but didn't tell him about them because I wanted to see what he came up with. He ended up coming up with the same devices during his research! Though the electrician's I've spoken to barely know what these devices are, and they insist that they've only been on the market a couple of years and recommended installing CO/ALR outlets and switches in our home for almost $1,700. I had two electrical companies tell me that they're "fix" is to install those outlets and switches, which upon finishing my research, I found out that those are NOT recommended anymore. My husband has been the one installing most of these, while I've only installed two myself. I would just recommend you making sure that you unscrew them a lot before putting the wires inside. My husband thought he had unscrewed it enough, but the wire fell out during the "tug test". We will be installing these throughout our entire home gradually.

Rated 5 out of 5 by from expensive, but works well and easy to install. REQUIRES A TORQUE SCREW DRIVER TO INSTALL. If yo... expensive, but works well and easy to install. REQUIRES A TORQUE SCREW DRIVER TO INSTALL. If you don't have one there are some cheap options available. there's at home depot, I don't have experience with it but it does the correct range of torques for this product. You need a screwdriver that does 10-15 inch pounds. There are instructions on how to do it without a torque screwdriver, but then the connector isn't certified safe, and why would you buy these expensive wire connectors then install them in a way that they arn't safe. From my experience it would be extremely easy to over-torque the aluminum connectors if you don't use a torque screwdriver. the screws actually dent the solid AL when they are torqued properly but you could easily dent them too much without the proper torque since aluminum is so soft. Electrical boxes can get snug with these in them, especially gfci outlets requiring 4 of the. if you want to safe yourself some hassle with the few boxes that have gfci outlets or a number of switches I'd recommend getting some of these: Lastly the prices of these jump around a lot, so if you see a bag of them that's cheaper than the others you might want to buy a bunch at that price. also good to know there are 25 packs available at (usually) a cheaper price per connector:

Rated 5 out of 5 by from The only safe DIY option for aluminum wire remediation There are only two products approved by the Consumer Products Safety Commission for safe remediation of aluminum branch wiring, and I chose this product because Alumiconn is one of them. Alumiconn connectors are the only option that homeowners can install themselves. The product is easy to install and a little larger than a wire nut. I have installed many of these throughout my home, and have had no issues with them. You simply strip back the insulation 5/16", insert the wire into the connector and tighten the screw to the recommended torque. I also purchased a torque screwdriver to make sure that I installed them correctly. You will need a minimum of 2 connectors for each outlet, and a minimum of 3 for each switch. If you also need to put these on aluminum ground wires in the box or on 3-way switches, you may need as many as 4 or 5 in a box. Fitting 4 connectors in a box is difficult, but can be done by careful routing and packing of the wires. If there is not enough room, installing a larger remodeling box is not that difficult. One of the other reviews here said to use Ideal In-Sure connectors if you don't have enough room for Alumiconn. Ideal Industries clearly states that In-Sure connectors are not to be used with aluminum wire. Alumiconn connectors are the only safe option. Using In-Sure connectors may increase the chance of a house fire.

Rated 4 out of 5 by from This is the best and only alternative to having a professional fix aluminum wiring dangers I have done a lot of research on the topic of aluminum wiring in homes and it turns out it is a very big potential fire danger. Many insurance companies will specifically not insure homes with aluminum wiring so if you have it ask if they do because you can potentially be left in a situation that they would not cover. The only other repair method for pig tailing copper wire to aluminum is called copalum which can only be performed by an electrician certified by the manufacturer. The special crimp tool for it is only leased and is quite expensive so the electrician that can do this repair method is quite expensive as well. The benefit to it is that it's a small cold weld crimp which is heat shrink wrapped so it fits inside existing electrical boxes easily. Alumiconn by comparison is a more do it yourself method. Basically it's a small three place bus bar which separates dissimilar metals so they can be electrically connected together in a safe manner. The manufacturer claims zero fires with this repair method. It has also carried both UL and US consumer product safety commission approval. Installation is straight forward. You remove a switch, outlet etc., clip the end of the aluminum wire off and strip some fresh material, insert in to one port and tighten the screw. Insert a small piece of copper wire in to another port and tighten, connect it to the device. If there is an out going wire it goes to the remaining port. The alumiconn connectors are only a little larger than a wire nut, but the entrance method does add some size and fitting three in to a standard box can be a challenge, but it doable. I had areas where there were seven wires joined in to one large wire nut. This type of connection requires the box to be cut out from the wall and a larger old work box to be installed in its place. This type of junction required eight alumiconn's to be used. Price wise these do add up quickly. As mentioned three are needed per box at least, possibly more. Still, it's cheaper than copalum and cheaper than a re-wire. There is a list on the manufacturers web site with a list of insurance companies which recognize alumiconn as a repair method so it theoretically is possible to get a discount on home owners insurance. I will say that it would have been nice if these were carried in stores, they are very difficult to come by, but ordering from the Home Depot's web site is easy and they can be returned unlike other sites which sell this product.

Rated 5 out of 5 by from The do-it-yourselfer solution to mitigating aluminum wiring risks My family moved in to a 1968 home about 6 months ago. Within the first month, we experienced two separate electrical issues, one of which was an outlet that was audibly and visibly arcing due to a loose wire connection. Concerned for my family's safety, I immediately began reading up on aluminum wiring. Not being at all experienced with electrical work, I then bought the Black & Decker Complete Guide to Electrical Wiring. Having read that cover to cover, I bought my first batch of Alumiconns, along with the reasonably priced Neiko torque screwdriver, and new receptacles and cover plates while I was at it (hey, they're cheap, and my time is valuable). My house is just over 2000 square feet, and after going top to bottom, I determined that I have about 120 electrical devices (receptacles, switches, and light fixtures). Doing the math, that's a pretty hefty investment in Alumiconns, but I consider it worth it for my family's safety. Doing the work a little at a time on the weekends, and having started about 45 days ago, I'm probably about halfway done now, maybe a bit further. Here's what I've learned: Yes, the Alumiconns are big, but if you make a point of bending both the existing and new wires in V's, you can stuff the Alumiconns pretty far back in the box. If you have more than 3 existing connections in a box, you can save space and money by using the Ideal Insure connectors for the Aluminum wires, then run an aluminum pigtail to the Alumiconn, and run copper to the device from there. The Insure connectors are TINY, taking up very little space. Technically not rated for aluminum connections, but neither are the wire nuts that were on there before, and the bigger concern is where the aluminum meets the copper devices, not where the aluminum meets additional aluminum. I've only run into this situation twice thus far, so not a common occurrence in my house at least. If necessary for space purposes, a remodeling box is surprisingly easy to install in finished drywall. You can achieve much greater efficiency by first cutting and stripping a whole bunch of 6" pigtails, and then just carrying them around in a bag with you. Having done that, I can do a receptacle or switch in under 15 minutes, and a light fixture/fan, depending on complexity, in 30-45 minutes. Tools like the Irwin Industrial self-adjusting Wire Strippers go a LONG way toward making wire stripping much easier. For the minimal additional cost, you might as well go ahead and replace the devices and cover plates while you're at it. I went with the newer TR style receptacles, as I have a toddler and another one on the way. If you're going to be putting in the time to take down a light fixture and put it back up again, are you happy with it? If not, now would be a great time to replace it. I hope this helps!
