The bad news has been delivered and your home was built using an Aluminum (AL) branch circuit wiring system. This means your house was built in the 1960’s or early 1970’s when copper prices were sky high due to the war in Vietnam as well as other global factors. Is this a situation that should be addressed?
The CPSC determined years ago that AL branch circuit wiring in residential dwellings is an ongoing fire hazard. Pitting, creep, oxidation and differences in the coefficient of thermal expansion in dissimilar metals (tying AL and Copper conductors together utilizing unapproved methods) all lead to break downs in AL wiring systems. These breakdowns cause resistance on wiring termination points that lead to heat which leads ultimately to fires. AL wiring systems are failing at rates that have made most insurance companies run from these properties in the course of a home sale in this day and age.
Service work done by homeowners or unqualified individuals has exacerbated these problems and made a bad situation even worse. You’re trying to sell your house. What can you do? You do not want to spend the money on a full house rewire. You’re leaving. But you do not want to leave your buyer and their Insurance Company with a fire starting menace either. There is only ONE CPSC approved method of mitigating the potential problems caused by these systems. It is called Copalum. This consists of putting a listed connector on the termination points in every electrical opening in your house. Switches, outlets, fixtures, fans, appliances that are hard wired; any place that a connection is done between AL wiring and dissimilar metal components or devices has to be addressed.
This method mitigates the thermal expansion differentials at your termination points and renders your wiring safe. In a perfect world, an update via rewiring is the best solution. However Copalum may be the practical solution for mitigation to those with a more limited budget, or those selling their homes and don’t want to make that kind of investment for a buyer.
A four bedroom house can typically be completed in about two weeks. Cullen Electric can assist you in Copalum installations as well as whole house rewires. We can present both options and their feasibility to you so you can make an informed decision on what’s best for you and your individual needs. Call today!
