Electrical Box Volume Calculator (DIY Project Download)

Every outlet box has a specific amount of space for conductors, devices, and fittings. We call that the box volume. You calculate box volume per 314. This is a tool for calculating how many wires you can legally fit in a box. Minimum box size required (in cubic inches):. In no case shall the volume of the box, as calculated in 314.16(A), be less than the fill calculation as calculated in 314.16(B). The minimum volume for conduit bodies shall be as calculated in 314.

electrical box volume calculator 2One of the mistakes often made is over loading an wire electrical box with too many wires. Calculate The Minimum Size Junction Box for Electrical Wiring. ARTICLE 314 C Outlet, Device, Pull and Junction Bozes, Conduit Bodies; Detailed box-fill calculation requirements are provided in 314.16(B)(1) through (5). How do I calculate box fill? How do you turn wires into cubic inches? Is a 12-2 wire a certain amount of cubic inches, or a 14-2, or 14-3? Do you have to count for the switch or recep? Just wondering.

How to calculate the the size of an electrical box required for a specific number or wiring conductors and devices. The National Electrical Code (NEC) specifies the maximum number of electrical conductors permitted in a box with a given volume. The number of conductors allowed to terminate in, or pass through, a box depends on several factors: the size of the individual wires, the number of receptacle outlets or switches mounted in the box and the number of.
