In connecting copper wires to aluminum cable lugs on an electrical installation, best practice needs to be followed to ensure a safe, efficient, and durable connection. There is galvanic corrosion when copper and aluminum are used together, which causes electrical resistance and degradation of the strength of the connection with time. In evading such problems, the right materials have to be employed, proper preparation techniques utilized, and follow installation processes that ensure conductivity as well as system integrity.

One of the key practices is to use the application of a bi-metallic washer or compound to avoid metal-to-metal contact. The use of an anti-oxidation compound will ensure a reduction in corrosion and provide a stable electrical connection. The second important practice is the use of correct crimping procedure with the right equipment in order to make certain that a reliable mechanical connection is formed between the lug and cable. Over-crimping and under-crimping may result in poor conductivity, over-heating, and even failure in the connection. The second is of equal importance to ensure that the lug size is the same as the cable gauge to prevent loose connections that would result in sparking or resistance development.
