In joining copper wires to aluminum cable lugs on an electrical installation, best practice must be adopted in a bid to ensure a safe, efficient, and long-lasting connection. Aluminum and copper combined experience galvanic corrosion and this results in electrical resistance and weakening of the strength of the connection with time. In avoiding such issues, the right materials must be used, proper preparation methods utilized, and follow install practices that allow conductivity and system integrity.

One of the main practices includes the application of the installation process of a bi-metallic washer or compound so that metal-to-metal contact may be prevented. An anti-oxidation compound applied will provide a corrosion inhibition as well as a stable electrical contact. Proper crimping technique with an appropriate tool being applied is the second main practice in an effort to create a good mechanical contact between the cable and lug. Under-crimping and over-crimping will lead to bad conductivity, over-heating, and even breakdown in the connection. The second one is also crucial to make sure the lug size is equal to the cable gauge so that no loose connections are formed which can form sparking or resistances.
