![]() ![]() The AlumiConn lug uses compression screws and can feature up to three ports, making wiring pigtails an easier process. It can be installed by anybody with common electrical knowledge. The AlumiConn lug would only cost you as low as $2.70 per connection. Although cheap, the COPALUM Crimp is a difficult option for people outside of COPALUM’s service area. These technicians may not be readily available based on where you live. One key disadvantage of the COPALUM crimp is that it can only be installed by a certified COPALUM technician. The COPALUM Crimp will cost between $12-$15 per wire. Although your wiring problems would surely be fixed, it is not the most practical solution for most people. The rewiring project could cost you $15,000 for a 2,100 square foot home. Add in another $1,000-$2,000 worth of copper along with the cost of a permit from your local government. If a new electrical panel is required, that could cost anywhere between $1,000-$3,000. While this is the most in-depth fix to a wiring issue, the cost for an electrician to rewire your home can run between $200-$500 per receptacle and switch depending on the region you live in. The problem is that aluminum wire failures happen slowly over an extended period of time, so it’s easy to miss the signs that issues are occurring.Īccording to the CPSC, rewiring your entire home or building would be the most thorough and permanent solution. Here are warning signals that indicate that you could have wiring problems. For this reason, many homes have already replaced their "AL" wires with copper wires. The overheating of your wiring could eventually lead to an electrical fire. As you continue to add appliances and electronics to your home, you exponentially increase the chance for your aluminum wiring to overheat. This means that more aluminum is required to support the same electricity as copper wiring. This was a hazardous situation.ĪLUMINUM WIRE REPAIR, WE PERMANENTLY REPAIR THE HAZARDS OF ALUMINUM WIRING!Ĭall us today for your aluminum wiring electrical safety inspection.The danger of aluminum material is that it is less conductive than copper. These splices were found outside of an approved electrical box and the surrounding insulation which was in contact also showed signs of over heating. These burned splices shown below were found in the attic in a home in the Montbello section of Denver in October of 2005. In addition to the severely burned wires and wirenuts, the box and transformer also showed significant signs of heat damage. These burned-up red and purple wirenuts at left were found at the furnace connection also at a home in the Southmoor section of Denver. The neutral wire bundle is completely fused together due to the heat damage. The damage done to the wirenuts and the amount of heat present is clearly obvious. These pictures are close ups of the burned up purple wirenuts after they were removed from the master bedroom switch. The wirenut contained 3 aluminum and 1 copper wire and operated a bath light that was working fine and not flickering. This picture is of a switch box found in a master bedroom in the Southmoor section of Denver in July 2004 clearly shows a burned Purple Wirenut on the neutral wires. ![]() However, being that this wirenut is filled with a flammable oxide-inhibitor and the manufacturer has stated that this wirenut is NOT INTENDED FOR A COMPLETE HOME RETROFIT, ( ) we believe it is best to leave aluminum wiring alone until such a time as it can be permanently repaired via re-wiring or COPALUM crimping.Ĭlick on any image below to enlarge that image. Accordingly, from what we have seen in the field, we agree with the Commission staff and can validate the laboratory testing in believing that this method of repair does not solve the problem of overheating present in aluminum branch circuits.Īt best we consider the proper application of Purple Wirenuts a temporary repair. In CPSC-sponsored laboratory testing, some brands of twist-on connectors have performed very poorly. The Commission staff has evaluated the effectiveness of “pigtailing” as a repair. ![]() The most often suggested unacceptable repair (“pigtailing”) involves attaching a short piece of copper wire to the aluminum wire with a twist-on connector sometimes called a wire nut (IDEAL Purple #65) the copper wire is connected to the switch, wall outlet or other termination device. While these repair methods are less expensive than COPALUM crimp connectors, we agree with the CPSC that these repairs are considered unacceptable and “does not solve the problem of overheating present in aluminum branch circuits.” Burned Purple (Ideal #65) Wirenuts found in the fieldĬAUTION: Many electricians, who are not COPALUM certified, recommend other repair methods. ![]()
