Electrical box inlet conduit on shear wall
You need to have the front of your box flush with the wall surface which means 1″. You can get 1″ mud rings – possibably resorting to an electrical contractor supply place. Think of it as a durable shell that shields wires from physical damage, moisture, heat, and electromagnetic interference. It also helps keep installations neat and organized, especially in environments. Would removing the diameters of the conduits from the shear depth be a realistic approximation? Does the concrete between the conduits fully contribute to the section's ability to resist shear? Refer ACI 318-08 (Section 6. Conduit is frequently required to run conductors through finished or concealed. It has a plywood panel so I am assuming this is a shear wall (I live in CA). Mark the pathway for the conduit using a level and pencil.
