What is the only approved repair method for aluminum wire terminations?

The approved repair method for aluminum wire terminations is the COPALUM connector. This method is specifically designed to address the issues associated with aluminum wiring, which can oxidize and create poor connections over time. The COPALUM connector provides a secure and solid connection that minimizes the risk of overheating and potential fire hazards.

The use of COPALUM involves crimping a copper connector to the aluminum wire, which helps establish a reliable connection that is resistant to corrosion. This reduces the potential for electrical failures that can occur with other types of connections. Additionally, the design of the COPALUM connector ensures that the joint remains stable over time, further enhancing safety and durability.

Alternatives like wire nuts, twist-on connectors, and mechanical splices may not provide the same level of safety and reliability when connected to aluminum wire. While they may be used in certain circumstances, they do not meet the specific challenges that aluminum wire presents, and are not sanctioned as the approved method for terminations in critical applications. Therefore, using COPALUM connectors is essential for ensuring the integrity and safety of aluminum wire connections.
