All insulted wire counted. +1(for ground) X by wire size factor wire factor 14awg=2 12awg=2.25 box should have a #stamp in the back(CU.IN.) number calculated has to be smaller than box example - all #14– 3(nuetral)3(ungrounded)1(ground) 7x2=14.All wire clamps together inside the box collectively count as 1. Each power conductor counts as 1. (all wires count even if unused) All equipment grounding wires (usually bare) collectively count as 1. Each Switch or outlet count as 2. Pigtails do not count. Now add up all of the above In the recent case I came across, the wires in the box showed some pretty bad heat damage, and I wonder if it had to do with the silicone filling up the entire box cavity. In this case, after making my repairs, I ended up using a dab of silicone around the gasket, and using the underground wire nuts that have the silicone inside them.In this video I show you how to do box fill calculations. These electrical box fill calculations can be done the easy way using the volume allowances stamped.
The junction box will be behind where a door opens, which is why I need to move the switch, and I'm not too concerned about the look of it. . box fill for 12 awg wire has a multiplier of 2.25. the ground wire is only counted once so with 3 cables plus the feed 1x2.25 for the ground 8x 2.25 for the 4 hot and 4 neutral. There is no switch or . Somebody else already mentioned the box fill chart in a comment. You can also find handy little box fill calculators on the web. EDIT: The answer that suggests using a single gang mud ring for a double gang box is spot on, that's what I meant by going to double-gang boxes, and you can certainly get the mud rings in metal or plastic. If the wires exceed the fill capacity of the box, it’s time to upgrade to a larger junction box. Remember, it’s always better to err on the side of caution when it comes to electrical work. Taking the time to calculate the fill capacity . I'm not certain that electrical code will accept that particular box as a junction box. You haven't mentioned the gauge and quantity of conductors needing to be spliced. Another answer describes box fill calculations for 12/2/2 .
I need to do a junction box. I wanted to use a a 4-11/16 box to extend a 8-3 and join 4- 14/2’s inside the same box. So since I have different size conductors in this box I have to go by the capacity of the box. So a 4-11/16x 1-1/2 has a capacity of 491ml So if I’m doing the math right I would do 24.6x8= 196.8ml 45.1x6= 270.6ml

Are Wagos considered something different than a wire nut despite doing the same thing?As many as the box fill will let you have. The limit on box fill is set in term of the number of wires entering the box -- splices don't count against it. That said, it's time to jump right into the box fill calculations. You have 9 10AWG box fill units there (1 for each hot and neutral entering, and 1 for all the grounds taken together).
I have a plug receptacle box that currently contains 3 in coming lines of #12 gauge that are pigtailed together to connect to the plug receptacle. So, 4 wires held together by a wire nut x 3 for a total of 12 wires. I want to add 2 new lines of #14 gauge and also pigtail together with the existing wires.On your splices, the fill rules require: 1 "wire" covers all grounds; 1 "wire" covers all cable clamps; 1 "wire" per actual wire brought in; So I count 6 wires. 14 AWG calls for 2.0 cubic inches per wire or 12ci. Since this is part of equipment, I would expect the provided wires would be included in the cubic inches the manufacturer states.
Electrical - AC & DC - grounding wires and junction boxes - I just want to clarify some grounding/box fill issues regarding junction boxes. I’ll list a couple of situations and the way I think it should be grounded and the box fill. Please tell me if I’ve got the rules correct. Say you run two EMT conduits to a is a separate ground wire needed when starting out with 12/2 steel armored cable with a proper connector at a 5785 and running through 500 wiremold finally ending up at a duplex receptacle in a 5745, 5747 or 5748 wiremold boxOverfilled boxes have the same potential danger as most electrical defects – arcing, overheating, and fire. Box Fill Code. The box fill code is described in 314.16 of the national electrical code (NEC). It states: Boxes and conduit bodies shall be of an approved size to provide free space for all enclosed conductors. 314.16 Number of Conductors in Outlet, Device, and Junction Boxes, and Conduit Bodies. Boxes and conduit bodies shall be of sufficient size to provide free space for all enclosed conductors. 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).
