Final answer:
COPALUM connectors are used to insulate aluminum and copper wiring before they are connected to outlets, ensuring a safe and reliable electrical connection.
Step-by-step explanation:
COPALUM connectors can be used to insulate aluminum and copper before connection to an outlet. This type of connector is specifically designed to create a safe and long-lasting connection between aluminum wiring and copper wiring, which are often found in electrical systems. It is important to insulate these metals properly before they are connected to an outlet to prevent potential problems like corrosion or thermal expansion that can lead to poor connections or even fire hazards over time.
