Grounding requirements for the outer door of the distribution box

148 (Grounding Conductor): Requires metallic junction boxes—and by extension, cabinet doors—to bond to ground using a designated grounding screw or clip. Which NEC rules apply to electrical cabinet doors? Let's unpack a few key standards that apply: NEC 250. 28 (Box Materials): Metal boxes. Bonding is just a way to join two parts, and is not actually connected directly to the earth point. This ensures that all the points are at the same earth potential. Contact Surface Treatment: Coatings or oxide layers should be removed from the connection area to expose the natural metal and reduce contact resistance. Since the stainless steel. What is the goal of the NEC requirements for grounding and bonding? Section 250.
