Charlie we are having a discussion in the shop about metal boxes having to be listed. Is that right? I can't find a specific requirement for that.
Hey Amy thanks for your question. There is no general rule that all metal boxes be listed although many are. Construction specifications in Part III of Article 314 support that concept and pull boxes are often fabricated for specific applications.
