Top best answers to the question «When to use metal electrical box»

Use a metal electrical box when metal-sheathed cable (also called armored BX cable) or metal conduit is running in or out of the box. Metal cable and conduit depend on the contact from its metal sheathing to the metal box to complete grounding. Also, use metal boxes with interior exposed applications.
