Final answer:
COPALUM connectors are used to safely join aluminum and copper wires before they are connected to an outlet, using a cold-welded connection to mitigate risks of electrical fires due to improper connections.
Step-by-step explanation:
Before aluminum and copper wires are connected to an outlet, COPALUM connectors are specifically made to make a secure and dependable connection between them. This is crucial because improper joining can result in loose connections and arcing because copper and aluminum have different rates of expansion and corrosion. By successfully joining these two distinct metals with a cold-welded connection, the COPALUM crimping method considerably lowers the possibility of electrical fires that may result from faulty connections.
