What is one reason for the popularity of aluminum busbars?

The popularity of aluminum busbars can be significantly attributed to their cost-effectiveness and availability. Aluminum is generally less expensive than copper, making it an attractive choice for many applications, especially in large-scale installations where material costs can have a substantial impact on the overall project budget. Additionally, aluminum is abundant and widely available, which further enhances its appeal for manufacturers and contractors looking to keep costs down while ensuring that materials are easily sourced.

Aluminum's suitability for low-voltage applications and its relatively lightweight nature also contribute to its popularity. However, while it is essential to recognize the advantages of other materials, the combination of lower cost and higher availability stands out as the primary reason driving the use of aluminum busbars in various electrical systems.
