Mounting Junction Boxes
You can place a VAC/16 junction box on any convenient and safe horizontal surface,
such as a floor, desk, or table. You can also mount (secure with screws) a VAC/16
J-box to a wall or other surface panel, as shown in Figure D–11. If you plan to
mount a J-box to any surface, follow the instructions in this section before you
connect any external devices to the the J-box device connectors or attach the J-box
to a VAC/16 board.
