Do electrical boxes have to be flush to the finished surface? Can they recess any depth into the wall by as much as 1/8" or 1/4"? Is there a minimum box depth for flush mounted receptacles and devices? I have a project where we will have masonry walls with 1-5/8" furring strips, and 5/8" drywall. The idea .Our non-tamper resistant GFCI's have a depth of 1.03" and we're not aware of any specific rule that quantifies minimum depth. The old standby is that per NEC 110.12 – “Electrical equipment shall be installed in a neat .A single-gang box 3 1⁄2 in. deep has a capacity of roughly 22 1⁄2 cu. in., enough space for a single device (receptacle or switch), three 12–2 w/grd cables, and two wire connectors. Double-gang boxes hold two devices; triple-gang boxes hold .
When you install an electrical box, make sure it is flush with the surface of this drywall strip; this will ensure the boxes are at the proper depth when the walls are finished. Most residential drywall is 1/2- or 3/8-inch thick, . Standard square boxes, also known as 4-inch boxes, provide plenty of depth for multiple applications (1¼ inches to 2.125 inches). The square corners offer even more interior space for multiple conductors and connectors.
Electrical Boxes vary in size, material, number of gangs, and shape and are designed for specific uses like junctions, outlets, and switch or fixture boxes for wiring in wall or ceiling. Use this . Is there a minimum box depth for flush mounted receptacles and devices? I have a project where we will have masonry walls with 1-5/8" furring strips, and 5/8" drywall. The idea is to put the conduit and boxes in the furring strip space between the masonry and drywall. That would allow a 2-1/4" deep box to be used.

They are designed to be recessed 1/8". Take a plastic box. Slide it against a 2x4 until it hits the stud stops. Measure the distance the box protrudes past the face of the 2x4. That distance is 3/8". (You can do this at Home Depot if you don't stock these items.) Use a 4" square 1-1/4" deep box and you have more than enough cubic volume. If anyone sells a single device box 1-1/4" deep it won't have sufficient volume. Biggest problem is the depth of the GFCI device itself. The Leviton slim GFCIs are claimed to protrude 1.026" into the box, but you still need clearance for things like wire bending.-Jon If you have a 15/16 device box you may well be able to mount a receptacle in it. You will not be able to wire it, box fill limitations prevent it. A 15/16" deep device box would be required to have it's volume marked but we can figure it roughly as 2 x 3 x .9375 = 5.625 cu. in. With one 14/2 NM and external clamps Hot, 2 cu in Neutral, 2 cu in What determines the depth of a pull box? Section 314.28 states the (2) min dimensions for the sides of the box based on the number and size of conduits entering the box, but where does the code refer to the depth of the box?
Assuming that I'm correct that since the conductors don't exit directly across from each other, the calculation would be (6x4")+4"+4" = 32" so a 32" x 32" box. My real question is concerning the depth of the pullbox. Do I use Table 312.6(A) to calculate the depth? I am installing (4) 400kCMIL, so I see that as 12". Is that correct? Does the NEC dictate the maximum depth inside a Christy/Oldcastle in-ground concrete electrical box? I looked at Section 110, Part V (Manholes and Other Electrical Enclosures Intended for Personnel Entry, All Voltages), but if it's there, I missed it. We have a Christy box at the intersection of two conduit runs. The box is 35"W x 64.5"L. What I'm not finding is the depth from the back of the KO to the rear surface of the box. It appears to be a short distance which means if you recess the box more than 1/4" or so, your emt is going to be in a pickle. Probably safer with the 1-1/2" box. Are EC's on here ok with the 1-1/2" deep box for a duplex receptacle? What is the smallest depth size for a 4"x4" wall recessed junction box in order to fit an 1-1/4" conduit on it? How about the depth for an 1-1/2" conduit? It's just to run AV and data cables in it, no wiring devices installed in the j-box just cables passing through.
The 1" depth is kind of an oddball because no one makes a round box metal or plastic that is 1".Pancakes are too shallow, octagons are too deep.I know there are mounting blocks that come with the outlet box built right in, but the color selection is very limited.
