What is an older method of joining conductors that is commonly referred to as a "Western Union"?

The term "Western Union" refers to a traditional method for joining conductors known as a splice joint. This technique involves overlapping the ends of two conductors and twisting them together to form a secure connection.

The splice joint is easy to perform and does not require specialized tools or equipment, making it a popular choice in various applications, especially in older electrical systems. This method creates a strong mechanical and electrical connection, ensuring that electrical current can flow without substantial resistance or loss.

While other techniques, such as compression joints or electric joints, offer their advantages in specific contexts, they generally require additional tools or materials and may not provide the same level of simplicity or effectiveness in every scenario. Thus, the splice joint remains a widely recognized method for joining conductors, particularly in historical or less technologically advanced contexts.
