When connecting copper wires to aluminum cable lugs on an electrical installation, best practice needs to be followed to achieve a safe, efficient, and durable connection. There is galvanic corrosion when copper and aluminum are used together, and this causes electrical resistance and degradation of the strength of the connection over time. In preventing such problems, the right materials should be employed, proper preparation techniques utilized, and adhere install procedures which enable conductivity and system integrity.

One such principal practice is employing the process of using a bi-metallic washer or compound so as to prevent metal-to-metal contact. An anti-oxidation compound in use will achieve a corrosion reduction as well as a stable electrical connection. The second important practice is the use of correct crimping technique by the right tool in an attempt to provide that a good mechanical connection is achieved between the cable and lug. Over-crimping and under-crimping may result in poor conductivity, over-heating, and failure in the connection. The second is of similar importance to ensure that the lug size is the same as the cable gauge to prevent loose connections that would cause sparking or resistance development.
