The NEC volume allowance per gang for mounting a device wider than a standard 50 mm (2 inch) box is described by which term?

Explanation:
In NEC box-filling rules, a device that is wider than a standard two-inch gang box needs extra space beyond the base one-gang volume. The term used for that extra allowance is a "double"—it means the device essentially spans two gang widths, so you multiply the per-gang volume by two to account for the larger device. This is why double is the best choice: it correctly reflects occupying two standard gang volumes. A single would undercount, triple would overcount for most wider-than-standard devices, and none would ignore the increased space need.
