Aluminum wiring isn’t inherently bad; rather, it differs from copper wiring and is generally considered inferior. However, when installed correctly and paired with the right equipment, it can function just as effectively and safely as copper wiring. The primary distinctions between aluminum and commonly used copper wires lie in aluminum’s softness, its tendency to corrode, and its expansion and contraction properties. These factors influence its performance and safety. Despite its reputation, aluminum wiring isn’t as problematic as often perceived—provided that electricians account for its characteristics and use the appropriate connectors and panels.
