As Joe is remodeling his parents' home, what type of wiring is he likely to encounter when installing new appliances?

The most likely type of wiring Joe might encounter when remodeling his parents' home is aluminum. This is because aluminum wiring was commonly used in residential construction, especially during the late 1960s through the early 1970s, largely due to its cost-effectiveness compared to copper. Although copper wiring is also prevalent and widely used in modern homes, aluminum wiring remains present in many older homes. It is crucial that anyone working with or installing new appliances recognizes the type of wiring they are dealing with, as aluminum has specific considerations, such as expansion and contraction, which can lead to connection issues if not addressed properly.

Copper, on the other hand, while being the favored choice for current standards due to its superior conductivity and reliability, might not be the predominant wiring type encountered in homes that were built or remodeled with aluminum wiring. Gold and silver are not typically used for wiring in residential applications due to their high cost and insufficient practical benefits for this purpose.
