Box Fill Question - 3 14/2s and a Receptacle in a 18.5 Box
I need to replace a box, and I’m not sure about the box full calculation. There are three 14/2 wires and one receptacle. The box previously had 2 - 14/2’s, but I tapped it for another device. I would normally use an old work box, but the drywall is a bit overcut. I’m planning to use a Madison box with the internal screws and secure it directly to the stud. The box I have is 18.5. They make one in 22.5, but I’d have to order it. I could also use a 2-gang instead, but I don’t have one. I was kind of hoping to get this done today, but I will wait if the box is too small. I wish Home Depot or Lowe’s carried these.

Both Home Depot and Lowes carry the Madison MSB22+ smart box.
My local Depot says out of stock. Lowes has it.
6 x #14 wires = 6
1 grounds = 1
1 device = 2
6 + 1 + 2 = 9 x 2 = 18 cu in.

Also cai24 you can take a look here. For the future if you need to know you can use this calculator to help you. Handy to have. There are a lot of box fill calculators on the Net but this will give you an idea.
