drawings may appear on the hinge side.**

** 2. Where box locations shown would interfere or cause associated
electrical equipment to interfere with architectural, structural or
mechanical features, install the box in a location which eliminates
interference but with the smallest deviation from the location shown.**

volume without the use of extension rings.**

** H. Boxes for Two or More Devices: Install gang boxes matching the
number of devices.**

** I. Masonry Boxes: Install masonry boxes where boxes are recessed in
wood, concrete block or brick or wood paneling. Saw‑cut the opening for
the boxes so that they will fit snugly in the opening. Install boxes
