What marking should suitable receptacles for aluminum wire have?

AL/CO
CO/ALR
ALR/CO
AL/COX

The correct answer is: CO/ALR

The marking "CO/ALR" on suitable receptacles for aluminum wire indicates compatibility with both copper (Cu) and aluminum (Al) wiring. This is crucial because aluminum wire is prone to oxidation and has different expansion and conductivity properties compared to copper wire. The "R" in the marking signifies that the receptacle is designed for use with aluminum wiring and includes features to accommodate its unique characteristics, such as special terminals or coatings that prevent galvanic corrosion. Using receptacles marked with "CO/ALR" ensures that they can safely and effectively handle the connection with aluminum wire, reducing the risk of overheating, arcing, or fires associated with improper connections. The other options do not reflect the proper industry standard for receptacles that are safe for use with aluminum wire, which is an essential part of electrical installations involving this type of wiring.
