Stainless Steel Distribution Boxes

Installation of electrical distribution boxes in steel structure houses

The short answer: in metallic conduit systems, use metallic boxes matched to the substrate condition, mount to structural members rather than panel ribs, and maintain a continuous EGC or verified EMT grounding path to every device. This article works through the three decisions that account for most rough-in correction notices in metal building projects: box type selection by wall condition, mounting method by substrate, and grounding compliance in metallic conduit systems. It does not apply to wood-frame or residential. A distribution box is the heart of any electrical system. Whether you're setting up a new electrical system or upgrading an existing one, proper installation of the panel is crucial for efficient and reliable power distribution. Proper grounding is critical in a metal building.
