When joining copper wires to aluminum cable lugs on an electrical installation, best practice must be observed to have a safe, efficient, and long-lasting connection. There is galvanic corrosion when aluminum and copper are combined, and this results in electrical resistance and weakening of the strength of the connection over time. In avoiding such issues, the correct materials must be used, adequate preparation methods used, and follow install procedures that allow for conductivity and system integrity.

One such main practice is utilizing the process of applying a bi-metallic washer or compound in order to prevent metal-to-metal contact. An anti-oxidation compound being utilized will provide a corrosion reduction as well as a stable electrical connection. The second significant practice is the application of proper crimping method using the appropriate tool in an effort to ensure that a strong mechanical link is established between the lug and cable. Over-crimping and under-crimping can lead to inadequate conductivity, over-heating, and even failure in the connection. The second is of equal significance to make sure that the lug size is identical to the cable gauge to avoid loose connections that would lead to sparking or resistance formation.
