In joining copper wires to aluminum cable lugs on an electrical installation, best practice has to be applied in ensuring a safe, efficient, and long-lasting connection. Aluminum and copper combined exhibit galvanic corrosion and this leads to electrical resistance and weakening of the connection strength over time. In avoiding such issues, suitable materials must be utilized, correct preparation methods utilized, and follow install procedures that allow conductivity and system integrity.

One of these fundamental practices is the application of the process of installing a bi-metallic compound or washer to prevent metal-to-metal contact. An anti-oxidation compound utilized will provide a corrosion reduction and stable electrical connection. The second fundamental practice is applying correct crimping technique using the appropriate tool in an effort to establish a firm mechanical connection between the lug and cable. Under-crimping and over-crimping will lead to low conductivity, over-heating, and even breakdown in the connection. The second one is also crucial to ensure the lug size is the same as the cable gauge so no loose connections are formed that can cause sparking or resistances.
