The Consumer Product Safety Commission (CPSC) reported that homes wired with old aluminum wire are 55 times more likely to have one or more connections reach Fire Hazard Conditions than copper wired home.

That’s a pretty alarming statement if you are a home owner or if you are in the market to purchase a home. House fires due to faulty aluminum wire or any electrical wire are typically the exception. However, this is one of those things that you want to check off your list before it’s too late.

The majority of aluminum wired homes today have been repaired by pig-tailing aluminum wire to copper wiring devices with non-approved twist-on wire nuts and electrical tape by homeowners and/or electrical contractors. These wire nut connectors are more likely to overheat and can eventually lead to fires.
The AlumiConn Aluminum to Copper Lug has proven to be the most cost effective method to repair your home or building old aluminum wire.

Is your home wired with Aluminum wire?

Aluminum wire was widely used across the United States between mid-1960s and mid-1970s due the sudden price increase of Copper. If your home was built outside of that time period, it is more likely that your house was wired with Copper wire.


How do I know if my home has Copper wiring?

You can take these simple steps to be sure


Aluminum Wire Marking
Step One: Electrical wires are typically exposed in the attic, crawl space or at the electrical panel. Look for the word Aluminum or AL on the plastic wire jacket. The marking is usually printed or embossed along the wire jacket.
Aluminum Wire Color
Step Two: If the marking is not visible, trace the wire until you find an area where the metal is exposed and not covered by the insulated jacket. Aluminum wires are the color of aluminum which is bright grey or silvery.

Now that I have identified that my house is wired with Aluminum Wire, why should I worry?

  • burnt plastic smells
  • warm faceplates
  • flickering lights
  • actual fire

Don’t wait until your options run out.

The problem is that Aluminum wire failures happen over a long period of time. So, if you are not experiencing any of those symptoms, it does not necessarily mean that the problem is not present.

  1. Complete re-wiring your home with Copper wire.
  2. Cold Weld an Aluminum wire to a Copper wire with a COPALUM Crimp.
  3. Splice an Aluminum wire to a Copper wire with an AlumiConn Lug.

Why is the AlumiConn Aluminum to Copper Lugs the most cost effective way?

Let’s look at the first recommended method.

According to CPSC, rewiring your entire home or building will be the most effective and permanent solution. True, this is the absolute way to completely eliminate Aluminum wiring problem. However, the cost for an electrician to re-wire your house runs between $200 to $500 per receptacle and switch depending on which region of the Country you live in.

Factor in another $1,000-$3,000 if you need a new electrical panel, $1,000 - $2,000 worth of copper wire alone, and the cost of a permit from your local municipality. The re-wiring project can easily run you $15,000 for a typical 2,100 square feet house. This is the sure way to eliminate the symptom, but it is definitely not the most affordable way.

The COPALUM Crimp will run you between $12 -$15 a wire. The biggest disadvantage for COPALUM crimp is that it can only be installed by a certified COPALUM technician. Depending where you live, these technicians might not be available near you.

The AlumiConn lug could cost you as low as $2.53 per connection. It can be installed by any certified electrician or even anyone with common electrical knowledge (How to Install an AlumiConn Aluminum To Copper Lug). Due to its ease of installation and the low price, we believe it is the most cost effective way to address your building aluminum wire.

Although, the AlumiConn lugs are quite simple to install, we highly recommend that you first consult with your local electrician before you take on fixing your aluminum wire connection.
