True or False: A grounding electrode conductor can be made from aluminum if certain size requirements are met.

A grounding electrode conductor can indeed be made from aluminum, provided that it meets specific size requirements. The National Electrical Code (NEC) recognizes aluminum as an acceptable material for grounding conductors, but it stipulates that the conductor must be appropriately sized based on the grounding system's requirements. This allows for flexibility in the choice of materials while ensuring that safety and performance standards are maintained. Furthermore, aluminum conductors must be properly installed to prevent issues such as corrosion and mechanical failure, which can arise if the material is not handled correctly. Therefore, the statement is true.
