Detailed box-fill calculation requirements are provided in 314.16 (B) (1) through (5). The volume from conductor fill, clamp fill, support-fittings fill, device or equipment fill, and equipment-grounding conductor fill, where applicable, must be added together. Proper calculation depends on understanding which items are counted and how much ...

The standard method for determining adequate box size first calculates the total box volume and then subtracts the total box fill to ensure compliance. For a standard 3 in. x 2 in. x3.5 in. device box, Table 314.16(A) shows the minimum permitted box volume to be 18 in.3 and allows up to a maximum of nine 14 AWG conductors.

Feeders, Calculations = Annex D. Go to annex D in your code book for reference. Example D1 (a) Using your calculator multiply 2500 x 3 = 7500. Small appliance load = 3000. Laundry load = 1500. Using your calculator add 7500, 3000, 1500 = 12000 now subtract 3000 = …

Feb 04, 2020· We will cover the basics for performing a box fill calculation, after which we will walk through a real-world example. It may be helpful to have a calculator available. The tables in this section, 314.16(A) and 314.16(B), are important to have on hand in order to do the volume calculation correctly.

Use nameplate rating in volt-amps or watts – If appliance is rated in amps then volt-amps = amps * volts. Voltage value is either 120 or 240. So, for a 120 volt appliance which is rated at 15 amps, 120 volts * 15 amps = 1800 volt-amps. Total # of water heaters. Volt-amp rating of water heater.
