electrical pull box clearance What clearance is required for ready and safe maintenance would depend on a number of factors and is a judgement call. I would suggest that you talk it over with the AHJ. . 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.
