What color coding is commonly used for PVC conduits?

The choice that indicates grey for electrical, orange for telecommunications, and blue for water is correct as it reflects the standardized color codes commonly used in the industry for PVC conduits. Grey is widely recognized as the color for electrical conduits due to its association with safety and signaling for electrical work. Orange is designated for telecommunications, representing that these conduits carry communication lines. The blue color coding is used to signify water, distinguishing plumbing systems from electrical and telecommunications systems. This color coding enhances safety and clarity in construction and maintenance, ensuring that workers can easily identify the purpose of different conduits at a glance.

Other choices do not conform to these standard practices, which could lead to confusion and potential safety hazards in electrical installations. Understanding these color codes is essential for anyone working with conduits, as it ensures compliance with industry standards and facilitates proper installation and maintenance.
