I recently got off the phone with a contractor from New Jersey who was asking several good questions about the AlumiConn connector. And one question that came up (that many other people ask, too) is whether or not you need to add antioxidant when you install an AlumiConn connector.
The answer is that you do not need to add any antioxidant to the AlumiConn connector because they already come pre-filled with a proprietary antioxidant sealant that coats the wires as you insert them into the connector!
This proprietary antioxidant helps to dramatically reduce oxidation – one of the primary problems with aluminum wiring. Oxidation occurs when oxygen comes into contact with metal and is particularly problematic with aluminum as the oxidation occurs faster than with copper. As this oxidation builds up on the wire, it causes more resistance for any electrical current to run through it, which results in heat build up and can possibly cause a fire.
So, it’s extremely important that you use antioxidant when dealing with aluminum wire! And since the AlumiConn connector comes pre-filled with the antioxidant, you can save time and money since you won’t need to buy any additional antioxidant or take the time to install it!
