You need to calculate based on the largest wire and you would also need to calculate for each fixture wire. If the fixture has 4 or fewer fixture wires with one ground and are entering the box from a domed fixture canopy you do not need to count them. Again I am not an electrician.314.28 Pull and Junction Boxes The National Electrical Code (NEC) has specific requirements detailing how to calculate the maximum numbers of conductors in boxes (outlet, device, junction, pull, etc.) and conduit bodies. Provisions for boxes and conduit bodies enclosing conductors 18 AWG through 6 AWG are in 314.16. These boxes are calculated from the sizes and numbers .
Using the electrical box size calculator is straightforward. Simply input the required parameters such as the number of conductors, wire gauge, and any additional devices or fittings. Then, click the “Calculate” button to obtain the recommended size for the electrical box. Formula:Introduction: The Electrical Pull Box Size Calculator is a valuable tool for electricians and professionals in the field. It aids in determining the appropriate size of an electrical pull box based on the number of conductors to be installed, ensuring proper wire organization and compliance with safety standards.To calculate the nominal diameter of any concentric-lay-stranded conductor made from round wires of uniform diameters, multiply the diameter of an individual wire by the applicable factors listed below:
Box fill is covered in article 314.16 of the NEC. The wires are counted by size and type for example 14 awg wire is 2 cubic inches for each hot , neutral and only counted once for the ground, if you have a pig tail that doesn’t add to the count, if you have 12 awg wire it is 2.25 for each with a mix of 14 & 12 the 1 ground wire counted will be the largest or 2.25. Each wire that enters the box and is terminated on a device counts as one. Each wire that passes through the box without making a joint counts as only one. All gound wires only count as one no matter how many ground wires you have. Wires that originate in the box and stay in the box, such as pigtails, do not count. Also the switch itself?When working with electrical boxes, it’s important to calculate the appropriate box fill to ensure safety and comply with electrical codes and regulations. Box fill refers to the amount of space in an electrical box that is occupied by conductors, devices, and fittings. This guide will walk you through the steps to accurately calculate box .
According to the National Electrical Code (NEC – United States) each item depending on the gage of wire. 14 Awg. requires 2 Cu. In. per conductor. 12 Awg. requires 2.25 Cu. In. per conductor. 10 Awg. requires 2.5 Cu. In. per conductor. 8 Awg. requires 3 Cu. In. per conductor. 6 Awg. requires 5 Cu. In. per conductorDetermining the size of underground pull and junction boxes to meet NEC 314.16 code standards is required to prevent damage to conductor insulation.

Conductor Count: All conductors entering the box must be counted, including grounding wires. How to Calculate Box Fill. To calculate box fill, follow these steps: Count all conductors entering the box. Determine the volume allowance for each conductor based on its size. Add volume allowances for devices, clamps, and fittings. Sum up all volume . 28 conductors x 24.6 ml = 688.8 ML plus wire connectors (It says pair 2 or 3 counts as one wire), If i calculate at 2 wires it would be 49.2 ML, however to be extra safe Ill add 5 additional wires. (5 x 24.6 ml = 123 ml) 688 + 123 = 811 ml 6 wires terminating in the box are 6. If there are cable clamps in the box, those count as 1. If they are outside the box, they don't count. 14Ga so 2 cubic inches per count. So: 18 or 20 cubic inches. Pigtails (wires that don't leave the box) are free. Wires count the same if they terminate on a wire nut or terminate on a device.
One option is to use a single gang mud ring for double gang box. you can get metal or plastic ones. You can definitely get deeper boxes, and you can also get box extenders, but at some point you'll be limited by the depth of your walls and you'll need to use double-gang boxes to get more room.
