Section 314.16 specifies the minimum volume size of junction boxes required for various types of electrical conductors. The volume size of a junction box is measured in cubic inches. It is determined based on the number and size of conductors within the box. When installing wall-mounted junction boxes for outlets or switches, a common height recommendation is around 12 to 16 inches from the floor. This height ensures easy accessibility for most individuals, including children and those with mobility limitations.

When electrical cables route from box to box, you must leave at least six inches of free conductor wiring in the junction box for connection purposes. In article 300.14, this technique is explained. 39.3.1 Electrical and communications system receptacles on walls shall be mounted between 15 inches (15" = 381mm) and 48 inches (48" = 1219mm) above the floor, measured at the centerline of the lowest receptacle.
Electrical equipment such as consumer units, meters (subject to agreement with the distributor) and socket-outlets should be mounted above the expected flood level. Cables supplying lower floor power should be routed through an upper floor . Common household wiring is usually 16, 14, or 12 AWG. As an example, the code allows 2 cubic inches of space for each 14-AWG conductor, so if you have two cables with three conductors each (a total of six), you’ll need a box that’s 4″ .
