(This message was added in version 6.7.0.) in /home1/looksmar/public_html/blog/wp-includes/functions.php on line 6114Aluminum wiring is a major electrical defect and New Jersey home inspectors<\/a> should inspect for this problematic wire during the electrical inspection of the home. During the years of 1965 and 1973 aluminum single strand wire was sometimes used instead of copper in residential construction. The substitution was primarily driven by soaring costs of copper wiring during this time frame.\u00a0<\/span><\/span><\/span><\/p>\n Very serious safety issues became apparent with this electrical wiring.\u00a0 The safety issues are caused by the properties of the aluminum in the wiring. Older connections become more of a safety hazard over time. NJ Home Inspectors<\/a> should describe the safety concerns associated with this type of wiring in the home. Inspectors should have their clients discuss the ramifications of having aluminum single conductor wire in their home with the client’s insurance carrier. Often insurance carriers have concerns with insuring homes when this type of electrical wiring is present.\u00a0<\/span><\/span><\/span><\/p>\n According to the NJ Home Inspection standards of practice<\/a>, home inspectors are required to report on the presence of this electrical wiring in a home that they are inspecting.\u00a0 According to the consumer products safety commission homes that have aluminum single conductor wire are 55 times more likely to have an electrical fire then homes without aluminum wire present.\u00a0 Aluminum single strand wire has qualities that make it a poor choice for residential wiring.\u00a0<\/span><\/span><\/span><\/p>\n Aluminum wire is more fragile than copper wire. Aluminum is not as durable and can break when exposed to bending the wire. Fatigue will cause the aluminum wire to break down, this breaking down will increase the internal resistance of the wire leading to a buildup of heat.\u00a0 Higher electrical resistance means that the wiring has to be a larger diameter of traditional copper electrical wiring. Aluminum wire will also break down in the presence of different metals. This break down is referred to as galvanic corrosion. Also, exposure to oxygen causes the wire to deteriorate on its outer surface. Aluminum wire is much more vulnerable to oxidation then copper wire. Over time this increased oxidation can make electrical connections weak creating fire hazards.\u00a0<\/span><\/span><\/span><\/p>\n Aluminum wire is softer than copper wire and is more malleable. Take for example when an aluminum wire is screwed to a terminal the wiring will continue to compress over time even though the wire is not being continually tightened. Eventually this defemination will create a loose connection and increase the possibility of electrical arching and fire hazards at these connections.\u00a0\u00a0<\/span><\/span><\/span><\/p>\n One of the greatest vulnerabilities of aluminum wire is its tendency for greater thermal expansion and contraction. Aluminum wire expands and contracts with changes in temperature. As current flows though the wire it will expand then contract as the current stops. Over time this expansion and contraction process will cause the connection to become loose, degrade then create fire hazards. Also, electrical current causes the wires to vibrate. This vibration is more pronounced in aluminum wire then copper wire. As time goes by this excessive vibration can cause the connections to become loose and create fire hazards.\u00a0<\/span><\/span><\/span><\/p>\n
